Answer:

 I₃ = I₀ 0.395

Explanation:

Polarized light passing through a polarizer must comply with Malus's law

         I = I₀ cos² θ

Before starting, let's analyze the angle between the polarizers, the second has the same angle with the first and the third, so it is at the midpoint

         θ₂ = 39/2 = 19.5

now let's analyze the light that passes through each polarizer, as the incident is unpolarized through the first polarizer half the intensity comes out

          I₁ = I₀ / 2

the second polarizer comes out

          I₂ = I₁ cos² 19.5

          I₂ = I₀ / 2 cos² 19.5

through the third polarized the intensity passes

          I₃ = I₂ cos² 19.5

          I₃ = (I₀ /2 cos² 19.5) cos² 19.5

          I₃ = I₀ 0.395

When you pour 0.0095 kg of 20.0°C water onto a 1.05-kg block of ice sitting in a large bowl initially at -15.0°C, the total heat transferred to melt the ice is approximately 350,699.603 J. First, let's calculate the heat required to raise the temperature of the water.

When you pour 0.0095 kg of 20.0°C water onto a 1.05 kg block of ice at -15.0°C, the water will transfer heat to the ice in order to melt it. To find the amount of heat transferred, we need to calculate the heat required to raise the temperature of the water from 20.0°C to 0°C and then the heat required to melt the ice.
First, let's calculate the heat required to raise the temperature of the water. The specific heat capacity of water is 4.18 J/g°C. We can use the formula Q = m × c × ΔT, where Q is the heat transferred, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the change in temperature.
Q = 0.0095 kg × 4.18 J/g°C × (0°C - 20.0°C) = -0.397 J
The negative sign indicates that heat is being lost by the water as it cools down.
Next, let's calculate the heat required to melt the ice. The latent heat of fusion for water (lf) is the amount of heat required to change 1 kg of ice into 1 kg of water at 0°C. The latent heat of fusion for water is approximately 334,000 J/kg.
Q = lf × mass of ice
Q = 334,000 J/kg × 1.05 kg = 350,700 J
So, the total heat transferred is -0.397 J + 350,700 J = 350,699.603 J.
In summary, when you pour 0.0095 kg of 20.0°C water onto a 1.05-kg block of ice sitting in a large bowl initially at -15.0°C, the total heat transferred to melt the ice is approximately 350,699.603 J.

Scientists have found out that the expansion rate of the universe is faster than previously estimated. This discovery was made by observing the motion of distant galaxies, supernovae, and cosmic microwave background radiation.

The current estimate of the Hubble constant is approximately 70 kilometers per second per megaparsec, meaning that for every 3.26 million light-years further away, a galaxy appears to be moving 70 kilometers per second faster. The explanation for the accelerated expansion of the universe is attributed to a mysterious force called dark energy. Dark energy is thought to comprise around 68% of the universe and acts as a repulsive force, counteracting gravity, and causing the expansion of the universe to accelerate. The precise nature of dark energy is still not well-understood, and it remains one of the major unsolved mysteries in modern cosmology. The discovery of the universe's accelerated expansion was awarded the Nobel Prize in Physics in 2011. Further research and observations, such as those conducted by the Hubble Space Telescope, continue to provide valuable insights into the expansion rate of the universe, the role of dark energy, and the overall evolution of the cosmos. Scientists are also exploring alternative theories and models to better understand the underlying mechanisms responsible for this accelerated expansion.

Given, speed of light through a clear solid is 2.05 × 108 m/s. We need to find whether the given solid isA) zircon where n = 1.92, B) diamond where n = 2.42, or C) quartz where n = 1.46. Let us use Snell’s law of refraction to find out whether the given solid is zircon, diamond or quartz.

Snells law states that:n1 sin θ1 = n2 sin θ2,where n1 = refractive index of the medium in which the incident ray is travelling,n2 = refractive index of the medium in which the refracted ray is travelling,θ1 = angle of incidence, andθ2 = angle of refraction. The refractive index n is given by:n = c/vwhere c is the speed of light in vacuum and v is the speed of light in the given medium. Let the given medium be denoted by x. The speed of light through a clear solid, x is given as 2.05 × 108 m/s. The refractive index of the medium can be calculated as:n = c/v = 3 × 108/2.05 × 108 = 1.46≈ 1.46Now, we can calculate the critical angle for the given medium using the formula:θc = sin−1 (n2/n1),where n1 = refractive index of the medium in which the incident ray is travelling,n2 = refractive index of the medium in which the refracted ray is travelling.

Using the given options and their refractive indices, we get the following values for critical angles for zircon, diamond and quartz:Zircon:θc = sin−1 (1/1.92) = 30.27°Diamond:θc = sin−1 (1/2.42) = 24.41°Quartz:θc = sin−1 (1/1.46) = 41.81°Now, we can calculate the critical angle for the given medium using the formula:θc = sin−1 (n2/n1),where n1 = refractive index of the medium in which the incident ray is travelling,n2 = refractive index of the medium in which the refracted ray is travelling.Let the given medium be denoted by x and its refractive index be denoted by nx. Since the given medium is a clear solid, we can assume that the angle of incidence is zero (i.e. the incident ray is perpendicular to the surface of the solid).θ1 = 0°Hence, we get the following expression for the angle of refraction:θ2 = sin−1 (n1/n2 × sin θ1) = sin−1 (n1/n2 × 0) = 0°Therefore, the incident ray will not be refracted when it enters the given solid. Since no refraction occurs, we can conclude that the critical angle for the given solid is zero.

Explanation:

From the question,

F = ma................... Equation 1

Where F = force exerted on the ball, m = mass of the ball, a = acceleration

But,

v² = u²+2as.............. Equation 2

Where v = final velocity, u = initial velocity, s = distance.

Given: v = 12 m/s, u = 0 m/s (from rest), s = 5.0 m

Substitute into equation 2 and solve for a

12² = 0²+2×a×5

144 = 10a

10a = 144

a = 144/10

a = 14.4 m/s²

Also Given: m = 5.2 kg,

Substitute into equation 1

F = 5.2×14.4

F = 74.88 N

Hence the force exerted on the ball is 74.88 N

Gravitational force between two masses m, and m, is represented as F = Gm₂ m₂ / r^2 where r = xi+yj + zkG, m, m₂ are nonzero constants and let's assume that I = 0

a) Calculation:For F = Gm₂ m₂ / r^2.

Using r = xi+yj + zk and let r^2 = x^2 + y^2 + z^2∴ F = Gm₂ m₂ / (x^2 + y^2 + z^2), Where G, m, m₂ are nonzero constants. Divergence of F = ∇ · F= 1/r^2(d/dx(r^2Fx) + d/dy(r^2Fy) + d/dz(r^2Fz))= 1/r^2(d/dx(r^2Gm₂ m₂ x/(x^2+y^2+z^2)^(3/2)) + d/dy(r^2Gm₂ m₂ y/(x^2+y^2+z^2)^(3/2)) + d/dz(r^2Gm₂ m₂ z/(x^2+y^2+z^2)^(3/2)))= 1/r^2(d/dx(r^2Gm₂ m₂ x/(x^2+y^2+z^2)) * (x^2+y^2+z^2)^(3/2) + d/dy(r^2Gm₂ m₂ y/(x^2+y^2+z^2)) * (x^2+y^2+z^2)^(3/2) + d/dz(r^2Gm₂ m₂ z/(x^2+y^2+z^2)) * (x^2+y^2+z^2)^(3/2))= 1/r^2(Gm₂ m₂ [2x(x^2+y^2+z^2)-3x^2]/(x^2+y^2+z^2)^(5/2) + Gm₂ m₂ [2y(x^2+y^2+z^2)-3y^2]/(x^2+y^2+z^2)^(5/2) + Gm₂ m₂ [2z(x^2+y^2+z^2)-3z^2]/(x^2+y^2+z^2)^(5/2))= 1/r^2(Gm₂ m₂ [(2x^2+2y^2+2z^2-3x^2)/(x^2+y^2+z^2)^(3/2)] + [2x^2+2y^2+2z^2-3y^2]/(x^2+y^2+z^2)^(3/2)] + [2x^2+2y^2+2z^2-3z^2]/(x^2+y^2+z^2)^(3/2)])= 1/r^2(Gm₂ m₂ [x^2+y^2+z^2]/(x^2+y^2+z^2)^(3/2))= 0.

Curl of F = ∇ × F= i(d/dy(Fz) - d/dz(Fy)) - j(d/dx(Fz) - d/dz(Fx)) + k(d/dx(Fy) - d/dy(Fx))= i(d/dy(Gm₂ m₂ z/(x^2+y^2+z^2)) - d/dz(Gm₂ m₂ y/(x^2+y^2+z^2))) - j(d/dx(Gm₂ m₂ z/(x^2+y^2+z^2)) - d/dz(Gm₂ m₂ x/(x^2+y^2+z^2))) + k(d/dx(Gm₂ m₂ y/(x^2+y^2+z^2)) - d/dy(Gm₂ m₂ x/(x^2+y^2+z^2)))= i(Gm₂ m₂ [-2xz]/(x^2+y^2+z^2)^(5/2)) - j(Gm₂ m₂ [-2yz]/(x^2+y^2+z^2)^(5/2)) + k(Gm₂ m₂ [(x^2+y^2-2z^2)]/(x^2+y^2+z^2)^(5/2))

b) Calculation:The line integral of F along a curve C can be evaluated by the following formula∫C F.dr = ∫∫ ( ∇ x F) ds, Where r is the position vector of the curve, s is the scalar parameter representing the curve, and the integral is evaluated from the initial point to the final point.

Using the curl of F obtained in part a) and for the surface with ∂S as C∫C F.dr = ∫∫ ( ∇ x F) ds= ∫∫ curl(F) ds= ∫∫ (-2xz i -2yz j + (x^2+y^2-2z^2)k) ds...[1]

Let's consider the surface S as a plane perpendicular to the z-axis of the form ax+by+c=0 and the curve C as the intersection of the plane and the cylinder x^2 + y^2 = a^2.

Let's choose the unit normal to the surface S as k (along the z-axis).

The curl of F is a vector field perpendicular to the plane and along the direction of k.

Thus the integral can be written as∫C F.dr = ∫∫ ( ∇ x F) . k ds= ∫∫ (x^2+y^2-2z^2) ds...[2]

Now let's evaluate the integral over the given plane ax+by+c=0. We can write x = t, y = (c-at)/b and z = 0, where t is the scalar parameter along the line of intersection of the plane and the cylinder (x^2 + y^2 = a^2).

Since the curve C is on the cylinder of radius a, we have x^2+y^2 = a^2 ⇒ t^2+(c-at)^2/b^2 = a^2On solving for t, we have t = (bc±ab √(a^2-b^2-c^2))/[a^2+b^2].

Substituting t in x and y, we get the curve C in the x-y plane as a function of the scalar parameter s asx = (bc±ab √(a^2-b^2-c^2))/[a^2+b^2]y = (c-at)/b= (c-(bc±ab √(a^2-b^2-c^2))/[a^2+b^2])/b.

Now we can evaluate the integral over the curve C, which is along the intersection of the plane and the cylinder.

Integral over C (x^2+y^2-2z^2) ds= ∫t₁^t₂ [(t^2 + [(c-at)^2]/b^2 - 2(0)^2)^(1/2)] dt= ∫t₁^t₂ [(a^2-b^2-c^2)t^2+2bc(c-at)+b^2c^2-a^2b^2]^(1/2) dt.

Now we can choose the value of t₁ and t₂ such that the square root in the integrand is minimized (so that the integral is path-independent).

This can be done by choosing the value of t that gives the minimum value of (a^2-b^2-c^2)t^2+2bc(c-at)+b^2c^2-a^2b^2 over the range of t from t₁ to t₂.

On differentiation with respect to t and equating to 0, we get the value of t = bc/(a^2+b^2).

Substituting this value of t in the integrand, we get the minimum value of the square root in the integrand to be |c| √(a^2+b^2)/|b|.

Thus the integral over C is given by∫C F.dr = ∫∫ (-2xz i -2yz j + (x^2+y^2-2z^2)k) ds= ∫∫ (x^2+y^2-2z^2) ds= ∫t₁^t₂ |c| √(a^2+b^2)/|b| dt= |c| √(a^2+b^2)/|b| (t₂-t₁).

Now we can see that the integral is path-independent as it depends only on the end points t₁ and t₂ and not on the path taken to reach them.

To bring an object to a height of 992 km above the surface of the Earth, we need to do work against the force of gravity. The work done is given by the formula;

W = mgh

where W is work done, m is mass of the object, g is acceleration due to gravity, and h is the height above the surface of the Earth.

Using the given values, we have;

m = 101 kg

g = 9.81 m/s²

h = 992 km = 992,000 m

W = (101 kg)(9.81 m/s²)(992,000 m) = 9.86 × 10¹¹ J

Converting J to MJ, we get;

W = 986 MJ

Therefore, the work necessary to bring a 101 kg object to a height of 992 km above the surface of the Earth is 986 MJ.

To launch the object into circular orbit at this height, we need to do additional work to overcome the gravitational potential energy and give it the necessary kinetic energy to maintain circular orbit. The extra work done is given by the formula;

W = (1/2)mv² - GMm/r

where W is work done, m is mass of the object, v is velocity of the object in circular orbit, G is gravitational constant, M is the mass of the Earth, and r is the distance between the object and the center of the Earth.

We can find the velocity of the object using the formula:

v = √(GM/r)

where √ is the square root symbol. Substituting the given values, we have;

v = √[(6.67 × 10⁻¹¹ N·m²/kg²)(5.97 × 10²⁴ kg)/(6,371 km + 992 km)] = 7,657 m/s

Substituting the values into the formula for work, we have;

W = (1/2)(101 kg)(7,657 m/s)² - (6.67 × 10⁻¹¹ N·m²/kg²)(5.97 × 10²⁴ kg)(101 kg)/(6,371 km + 992 km)

W = 4.58 × 10¹¹ J

Converting J to the required units, we get;

W = 458 MJ

Therefore, the extra work needed to launch the object into circular orbit at a height of 992 km above the surface of the Earth is 458 MJ.

The acceleration of a satellite is dependent on the strength of the gravitational field it is experiencing. The stronger the gravitational field, the greater the acceleration of the satellite.

The gravitational force between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them. Therefore, as a satellite orbits around a planet, the gravitational force acting on it changes based on its distance from the planet.
At the closest point of its orbit, the satellite experiences the strongest gravitational force, causing it to accelerate towards the planet. As it moves away from the planet, the gravitational force decreases, causing a decrease in acceleration. At the furthest point of its orbit, the gravitational force is at its weakest and the satellite experiences the least acceleration. This relationship between acceleration and the strength of the gravitational field is essential for understanding the mechanics of orbiting satellites.

The satellite's acceleration is equal to the gravitational field strength experienced by the satellite.
1. A satellite in orbit experiences a force due to Earth's gravity, which pulls it towards the Earth's center.
2. This force causes the satellite to accelerate towards the Earth, resulting in a curved path or orbit around the Earth.
3. According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Therefore, acceleration (a) can be calculated as a = F/m, where F is the gravitational force and m is the mass of the satellite.
4. The gravitational field strength (g) at a particular location is defined as the force per unit mass acting on an object due to gravity. Hence, g = F/m.
5. Comparing the expressions for acceleration (a) and gravitational field strength (g), we see that they are equal: a = g.

Answer:

yes

Explanation:

All Motion is relative to a reference point. Object appears to move whether object moves, the reference point moves, or both move. is the distance traveled by an object over the period of time in which it moved. Ex - a racecar driver completes a three-mile lap in 60 seconds.

The statement "All Motion is relative to a reference point." is True.

An inertial frame of reference is a frame of reference in which the Newton's laws are valid. In this frame of reference, the objects do not accelerate without any external force. All frames of reference moving with constant velocity are considered stationary.

In a non-inertial frame of reference, the Newton's laws will not work. They are moving with an acceleration.

All Motion is relative to a reference point. Object appears to move, the reference point moves, or both move is the distance traveled by an object over the period of time..

Thus, the statement "All Motion is relative to a reference point." is True.
