A moon orbits a planet in the xy plane, as shown in the figure. You want to calculate the force on the moon by the planet at each location labeled by a letter (A,B,C,D). At each of these locations, what are
(a) the unit vectorrhatitalic,
(b) the unit vectorFhatitalicin the direction of the force

Answer:

b. 1.1 m/s c. -1.1 m/s

Explanation:

b.

m x v=f x t

The mass is 10 kg

10 x v (equation for momentum) = f x t (impulse)

you would find the impulse by finding the area under the graph, and then dividing by the mass

So in this case:

10 x v = 11

then divide by the mass

v = 11/10

v= 1.1 m/s

c.

F x t = impulse

we are trying to find force (magnitude)

impulse/t = F

we said that in order for it to stop the impulse for b would be 11, so if thats the case it would be 11 but it would be negative because when going in a positive direction and suddenly stopping the direction changes.

-11/t = F

to find t all we need to do is find the amount of seconds between 10 and 20, that would be 10.

-11/10 = F

F= -1.1 m/s

Answer B:

The velocity of the box at 10 seconds is :

              m x v=f x t

Given Information :

Mass(m)=10kg

Therefore, the velocity of the box at 10 seconds is 1.1m/s.

Answer C:

The magnitude and direction of that force be :

F x t = impulse

To find t all we need to do is find the amount of seconds between 10 and 20, that would be 10.

The magnitude and direction of that force will be -1.1m/s.

The same thing could reasonably be said about multicollinearity. Specifically, the reason for this is due to the violation of the assumption of independent predictors.

Let us understand what these terms mean:

In statistical analysis, multicollinearity is the high correlation among predictors in a regression model. It is problematic because of its adverse effects on the model, including making it difficult to determine the effect of an independent variable, coefficients becoming insensitive to small changes in the model, and reducing the reliability of the model.

In regression analysis, independent predictors are those variables that contribute to the prediction of the dependent variable or outcome, and their inclusion in the model improves the accuracy of the prediction of the model.

In a regression model, it is an assumption that predictors are independent, which means that the predictors have little to no correlation with each other. If this assumption is violated, it is known as multicollinearity.

Therefore, the same thing could reasonably be said about multicollinearity. Specifically, the reason for this is due to the violation of the assumption of independent predictors.

The correct answer is A) We do not yet have a theory that links quantum mechanics and general relativity.

The Planck era refers to the first fraction of a second after the Big Bang when the universe was extremely hot and dense, and the energy density was so high that the laws of physics as we know them break down.

Therefore, to understand the behavior of the universe during this era, we need a theory that can unify quantum mechanics, which describes the behavior of particles at the atomic and subatomic scale, and general relativity, which describes the behavior of gravity at the cosmological scale.

Currently, there is no such theory, and this is why we cannot describe what happened during the Planck era.

Given information:

Mass of Justin = 55 kg

Height of water slide = 8 m

Speed at the bottom = 12m/s

Mechanical energy (kinetic or potential energy) is the energy of an object in motion or the energy stored by an object in its position. Mechanical energy is also the engine of renewable energies.

Now,

the total mechanical energy is:

   E(i) = U = mgh

⇒ E(i) = 55×9.81×8

⇒ 4004 J

Kinetic energy is the energy that an object possesses due to its motion. If we want to accelerate an object, we must apply a force. The application of force forces us to work. After the work has been done, the energy has been transferred to the object and the object will move at a new constant speed.

And, the kinetic energy :

   E(f) = K = (1/2) mv²

⇒ E(f) = 0.50 × 50 × 12

⇒ E(f) = 3600 J

So, the energy lost by the Justin:

   ΔE = E(i) -E(j)

The change  in momentum is 435.6 Kgm/s

Newton's second law of motion states that the rate of change of momentum of an object is directly proportional to the force applied, and the change in momentum takes place in the direction of the applied force.

The mathematical expression of Newton's second law is as follows:

F = dp/dt

where F is the force applied on the object, p is the momentum of the object, and t is time. dp/dt represents the rate of change of momentum over time.

From this equation, we can see that the change in momentum (Δp) of an object due to a force is equal to the product of the force (F) and the time (Δt) over which the force is applied:

Δp = F Δt

From Newton's law;

Ft = mv - mu

Where mv - mu = Δp or change in momentum

Answer:

81.6 m

Explanation:

Answer: 81.6 m.

The time it takes gravity to slow 40 m/s to zero when it teaches maximum height is

-v(initial) / -g = t

-40 m/s / -9.8 m/s^2 = 4.08 s

The height reached is the average velocity times this time 4.08 s, with v(avg) = [v(initial) + v(final)] / 2 with v(final) = 0. v(avg) = v(initial) / 2 = 40 m/s / 2 = 20 m/s.

So the distance d of maximum height is

d = v(avg)•t

d = 20 m/s • 4.08 s = 81.6 m.

Answer:

80m

Explanation:

time taken for stone to reach max-height is t=final velocity - intial velocity / acceleration due to gravity

t=v-u/g

where:

v=0 , u=40m/s ,g=-10m/so

: t=0-40/-10

t=4secs

The direction of the electrostatic force between the two negative charges can be determined by the signs of the charges. Like charges repel each other, while opposite charges attract each other. In this case, both charges are negative, so they will repel each other.

To calculate the magnitude of the electrostatic force between the charges, we can use Coulomb's law. Coulomb's law states that the electrostatic force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically, we can express this as:
F = k * (q1 * q2) / r^2
Where F is the electrostatic force, k is Coulomb's constant (9 x 10^9 Nm^2/C^2), q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.
Plugging in the given values, we get:
F = 9 x 10^9 * (-2.5 C) * (-9.0 C) / (0.25 m)^2
F = 4.05 x 10^-6 N
Therefore, the magnitude of the electrostatic force between the two charges is 4.05 x 10^-6 N, and it is repulsive in direction.

As you can see in the picture wave E has the  highest frequency. which means since A has the lowest  frequency and E has the highest frequency answer 2 would be correct the amplitude increases from A to E.

Amplitude of a wave is the strength of the wave. It is measured from the central line of the wave to the top of the crest or bottom of the trough. Thus, higher amplitude waves will gives sharp crests and troughs. Here amplitude is increasing from A to E.

Amplitude is a parameter measuring the strength of a wave. It is the maximum displacement moved by the wave from its equilibrium position. The vibrational path will be twice that of the amplitude of the wave.

As the amplitude of the wave increases its intensity increases. Both are in direct proportion with the frequency and energy of a wave. For instance the amplification of sound waves increases the intensity of waves that we hear.

The distance between two consecutive crests or troughs is the wavelength of the wave not amplitude. Amplitude is measured from the axis line to the top of the crest thus, from exact middle of the wave crest to the top or to the bottom of trough.

Thus, higher amplitude waves will gives sharp crests and troughs. Here amplitude is increasing from A to E

The best description of how electric charges respond to electrical fields is that negative charges move in the direction of the electric field, while positive charges move in the direction opposite to the electric field. Option b

Electric charges are particles that carry electric charge. When they are placed in an electrical field, they are subject to a force, which can cause them to move. The direction of the movement depends on the charge of the particle and the direction of the field.
Option (a) states that both positive and negative charges move in the direction of the electric field. This is not entirely true. In reality, the direction of movement depends on the charge of the particle. Positive charges move in the direction opposite to the electric field, while negative charges move in the direction of the electric field.
Option (b) is more accurate. Negative charges move in the direction of the electric field. This is because the force on a negative charge is in the same direction as the electric field. Therefore, negative charges are attracted to regions of high electric field.
Option (c) is not true. Positive charges move in the direction opposite to the electric field. This is because the force on a positive charge is in the opposite direction to the electric field. Therefore, positive charges are repelled from regions of high electric field.

Terminal velocity is the maximum velocity that an object reaches during free fall or a similar situation. It is the result of two opposing forces: air resistance and gravity. The terminal velocity of an object varies depending on its shape, size, and weight.

The distance an object has to fall to reach terminal velocity varies depending on the object's properties and other factors, such as the air resistance, which affects how quickly the object reaches terminal velocity. An object accelerates as it falls, increasing in velocity as it gets closer to the ground. However, as the object falls, the force of air resistance increases. Eventually, the air resistance is great enough to counteract the force of gravity. When the two forces are equal, the object reaches its terminal velocity. The time it takes an object to reach terminal velocity depends on several factors. These include the shape of the object, its weight, and the density of the air. For example, a lighter object will reach terminal velocity faster than a heavier object. Similarly, a streamlined object, such as a feather, will reach terminal velocity more slowly than a flat object, such as a sheet of paper. The distance an object has to fall to reach terminal velocity varies depending on these factors. In general, however, objects that are heavier and less streamlined will reach terminal velocity more quickly than lighter and more streamlined objects.

In conclusion, the distance an object has to fall to reach terminal velocity varies depending on several factors, such as the object's weight and shape, as well as the density of the air. In general, heavier objects and those that are less streamlined will reach terminal velocity more quickly than lighter and more streamlined objects.

The acceleration of the skydiver is approximately +5.4 m/s².

We can use Newton's second law of motion, which states that the net force acting on an object is equal to its mass times its acceleration:

Net force = mass x acceleration

In this case, the net force is the force due to gravity minus the force due to air resistance:

Net force = force due to gravity - force due to air resistance

So we have:

(700 N) - (322 N) = (70 kg) x acceleration

Simplifying this equation, we get:

378 N = (70 kg) x acceleration

The rate of heat flow through the wall is 23.71 W/m². To find the rate of heat flow through the wall, we need to calculate the thermal resistance of each layer and add them together. Then, we can use the formula for heat transfer through a composite wall to find the rate of heat flow.

First, we need to find the thermal resistance of the wood layer. Thermal resistance (R) is equal to thickness (d) divided by thermal conductivity (k). So, for the wood layer:

R = 0.03 m / 0.08 W/(m · K) = 0.375 m²K/W

Next, we need to find the thermal resistance of the foam layer:

R = 0.022 m / 0.01 W/(m · K) = 2.2 m²K/W

Now, we can add the thermal resistances of the two layers together:

Rtotal = Rwood + Rfoam = 0.375 m²K/W + 2.2 m²K/W = 2.575 m²K/W

Finally, we can use the formula for heat transfer through a composite wall:

Q = (T1 - T2) / Rtotal

where Q is the rate of heat flow, T1 is the temperature on one side of the wall, T2 is the temperature on the other side of the wall, and Rtotal is the total thermal resistance of the wall.

Plugging in the values we have:

Q = (-10°C - 19°C) / 2.575 m²K/W = -29°C / 2.575 m²K/W = -11.27 W/m²

Note that the rate of heat flow is negative, indicating that heat is flowing from the inside of the house to the outside, as expected. To get the absolute value of the rate of heat flow, we can take the magnitude of the negative value:

|Q| = 11.27 W/m²

Therefore, the rate of heat flow through the wall is 23.71 W/m².

With the given measurements of the distance between the screen and the slits, as well as the separation between the dark bands on the screen, the wavelength of the light can be calculated using the formula for the interference pattern.

In the double-slit interference pattern, the dark bands are formed due to destructive interference between the waves from the two slits. The distance between adjacent dark bands, known as the fringe separation, can be used to determine the wavelength of the incident light.

In this scenario, the dark bands on the screen are measured to be 1.7 cm apart. The distance between the screen and the double slits is given as 5.0 m, and the separation between the slits is 0.18 mm.

Using the formula for the fringe separation in the double-slit interference pattern, which is given by:

λ = (d * L) / D

where

λ is the wavelength of the incident light,

d is the separation between the slits,

L is the distance between the screen and the slits, and

D is the fringe separation,

we can rearrange the formula to solve for the wavelength:

λ = (D * d) / L

Plugging in the given values, with D = 1.7 cm (or 0.017 m), d = 0.18 mm (or 0.00018 m), and L = 5.0 m, we can calculate the wavelength of the incident light.

λ = (D * d) / L

λ = (0.017 m * 0.00018 m) / 5.0 m

Simplifying the expression:

λ = 0.00000306 m / 5.0 m

λ ≈ 6.12 x 10^-7 m
