Explanation:

After World War II the only coal available to burn residentially, either for cooking or warmth, was of poor quality and contained large amounts of contaminants that made its fumes toxic. So when millions of homes in London burned this low quality coal and the local atmosphere over and around London stagnated, there was nowhere for the fumes to go. This stagnation allowed the toxic coal fumes to build up until they became physically harmful to humans and animals.

Burning of low quality coal was ultimately responsible for London’s “killer fog” in 1952.

This is a type of sedimentary rock which is combustible and contain high amounts of carbon and hydrocarbon.

The low quality coal contained a lot of contaminants which was released into the atmosphere thereby creating the “killer fog” which adversely affected residents.

The Lorentz transformation demonstrates that the wave equation is consistent with the principles of the special theory of relativity, as the equation remains unchanged when transforming between inertial reference frames.

The Lorentz transformation plays a crucial role in the special theory of relativity, as it relates the coordinates and time of events in one inertial frame to those in another inertial frame moving at a constant velocity relative to the first. The 1-D wave equation represents how a wave propagates through space and time and is given by:

∂²y/∂t² = c²∂²y/∂x²,

where y is the wave function, c is the speed of the wave, and t and x are time and position coordinates, respectively.

Now, let's consider the Lorentz transformations for space and time coordinates:

(i) x' = γ(x - vt),
(ii) y' = y,
(iii) z' = z,
(iv) t' = γ(t - vx/c²),

where x', y', z', and t' are the coordinates and time in the moving frame, γ = 1/√(1 - v²/c²), and v is the relative velocity between the two frames.

By directly substituting the Lorentz transformations (i) and (iv) into the 1-D wave equation, you will see that the wave equation remains invariant under these transformations. This means that the form of the wave equation is preserved, and the laws governing the propagation of the wave are the same in both the stationary and moving frames.

Sure! Here are the steps for calculating the velocity and distance traveled by the car after 50 seconds :

Step 1: Calculate the velocity using the equation:

\(v = u + at\)

where:

- \(v\) is the final velocity

- \(u\) is the initial velocity (0 m/s, as the car starts from rest)

- \(a\) is the acceleration (3 m/s²)

- \(t\) is the time (50 seconds)

Substituting the values into the equation:

\(v = 0 + (3 \, \text{m/s²}) \times (50 \, \text{s})\)

Step 2: Calculate the distance traveled using the equation:

\(s = ut + \frac{1}{2}at^2\)

where:

- \(s\) is the distance traveled

- \(u\) is the initial velocity (0 m/s)

- \(a\) is the acceleration (3 m/s²)

- \(t\) is the time (50 seconds)

Substituting the values into the equation:

\(s = 0 \times (50 \, \text{s}) + \frac{1}{2} \times (3 \, \text{m/s²}) \times (50 \, \text{s})^2\)

Now, let's simplify these equations:

\(v = 3 \times 50\)

\(s = \frac{1}{2} \times 3 \times 50^2\)

Calculating the results:

\(v = 150\) m/s

\(s = 3750\) meters

Therefore, after 50 seconds, the car will have a velocity of 150 m/s and would have traveled a distance of 3750 meters.

The statement that best describes a perfectly inelastic collision is

C. A surfer falls off of his surfboard when a wave hits him.

A collision is the interaction between two bodies in such a way that the momentum and velocity of one body gets changed due to the presence of other body. There are three types of collision-

1. Elastic collision

2. Inelastic collision

3. Perfectly inelastic collision.

In all types of collision , the momentum of the system before collision and after collision always remains same or we can say that momentum is conserved in collisions

An elastic collision is the one in which kinetic energy is also conserved and coefficient of restitution is one. Both the bodies move separately with different velocities after elastic collision.

In inelastic collision  there is a loss of kinetic energy and coefficient of restitution is less than one.

In perfectly inelastic collision there is maximum loss of kinetic energy and coefficient of restitution is zero. Both the bodies stick together after collision and move with same velocity

Coefficient of restitution is the  ratio of  relative velocity of separation after collision to relative velocity of approach before collision.

A surfer falls of his surfboard when a wave hits him is an example of perfectly inelastic collision because in this when water hits the surfers he falls of and sticks to the water , and will also now move with the velocity of water .

So  when the surfer falls off his surfboard when a wave hits him is perfectly inelastic collision.

If the primary wire's power is 10 A and one branch's power is 4 A, another branch's power will be 6A.

According to Kirchhoff's current law (KCL), the total current flowing through a parallel route circuit's junction equals the total current flowing away from it.

Provided that one of the two branches through which power exits the intersection has a flow of 4A, and also that the junction's overall flow entering it is 10A, the entire current going the junction should be 10A.

Consequently, the second wire's power may be expressed as;

I = I1+ I2 [ where I= total current (10A);

                I1= current in one branch (4A) &

                I2= current in another branch]

⇒I2 = I - I1

⇒I2 = 10A - 4A

⇒I2 = 6A

Therefore, it can be concluded that when the primary wire bears 10A power having 4A in one of its branches, another branch carries 6A power.

Answer:is true

Explanation:

The spring constant is approximately 0.8 N/m

To find the spring constant, we can use Hooke's law, which states that the force exerted by a spring is directly proportional to the displacement from its equilibrium position.

The formula for the period of oscillation of a mass-spring system is:

T = 2π * sqrt(m/k)

Where:

T is the period of oscillation,

m is the mass of the glider, and

k is the spring constant.

In this case, the glider is pushed 12 cm, so the amplitude of the oscillations is A = 0.12 m.

The period T is given as 24.0 s for 20 oscillations, which means the period for one oscillation is T/20 = 1.2 s.

Substituting the known values into the equation, we have:

1.2 = 2π * √(0.3/k)

Solving for k:

sqrt(0.3/k) = 1.2 / (2π)

\(0.3/k = (1.2 / (2π))^2\)

\(k = 0.3 / [(1.2 / (2π))^2]\)

Using a calculator, we can calculate the value of k:

k ≈ 0.8 N/m

Therefore, the spring constant is approximately 0.8 N/m

Answer:

\(60^{\circ}\) (assuming that air resistance is negligible.)

Explanation:

Let \(g\) denote the gravitational field strength. If air resistance on the projectile is negligible:

Let \(\theta\) denote the angle at which the projectile is launched. Let \(v\) denote the initial velocity of the projectile:

Also because air resistance is negligible, vertical velocity of the projectile will be \(v_{y} = (-u_{y}) = (-v\, \sin(\theta))\) right before the projectile lands. In other words, while the projectile was in the air, the change in vertical velocity would be \((-v\, \sin(\theta)) - (v\, \sin(\theta)) = (-2\, v\, \sin(\theta))\).

Divide the change in velocity by acceleration to find the duration of the flight:

\(\begin{aligned}t &= \frac{v_{y} - u_{y}}{a_{y}} \\ &= \frac{(-v\, \sin(\theta)) - (v\, \sin(\theta))}{(-g)} \\ &= \frac{(-2\, v\, \sin(\theta))}{(-g)} \\ &= \frac{2\, v\, \sin(\theta)}{g}\end{aligned}\).

Range measures the horizontal distance that this projectile has travelled. At a constant horizontal velocity of \(u_{x} = v\, \cos(\theta)\), this projectile would travel a distance of:

\(\begin{aligned}(\text{range}) &= u_{x}\, t \\ &= (v\, \cos(\theta))\left(\frac{2\, v\, \sin(\theta)}{g}\right) \\ &= \frac{2\, v^{2}\, \sin(\theta)\, \cos(\theta)}{g}\end{aligned}\).

Apply the double angle identity \(2\, \sin(\theta) \, \cos(\theta) = \sin(2\, \theta)\) to further simplify this expression:

\(\begin{aligned}(\text{range}) &= \cdots \\ &= \frac{2\, v^{2}\, \sin(\theta)\, \cos(\theta)}{g} \\ &= \frac{v^{2}\, (2\, \sin(\theta)\, \cos(\theta))}{g} \\ &= \frac{v^{2}\, \sin(2\, \theta)}{g}\end{aligned}\).

Note that in this question, \(v^{2}\) and \(g\) are both constant. Hence, for another angle of elevation \(\hat{\theta}\), the range of the projectile will be the same as long as \(\sin(2\, \hat{\theta}) = \sin(2\, \theta)\).

\(\sin(2\, \hat{\theta}) = \sin(2\, (30^{\circ}))\).

Since \(0^{\circ} \le \hat{\theta} \le 90^{\circ}\), \(0^{\circ} \le 2\, \hat{\theta} \le 180^{\circ}\):

\(\sin(2\, \hat{\theta}) = \sin(180^{\circ} - 2\, \hat{\theta}) = \sin(2\, (90^{\circ} - \hat{\theta}))\).

Therefore, \(\hat{\theta} = 90^{\circ} - \theta = 90^{\circ} - 30^{\circ} = 60^{\circ}\) will ensure that \(\sin(2\, \hat{\theta}) = \sin(2\, \theta)\). Launching the projectile at \(60^{\circ}\) will reach the same range.

\(\begin{aligned}(\text{new range}) &= \frac{v^{2}\, \sin(2\, (60^{\circ}))}{g} \\ &= \frac{v^{2}\, \sin(2\, (30^{\circ}))}{g} = (\text{original range})\end{aligned}\).

Given:

The length of the outdoor track is: l = 400 m

The time taken to complete one complete lap around the track is: t = 100 s

To find:

The average speed and the average velocity

Explanation:

The average speed of an object is defined as the total distance covered by an object divided by the total time it took to complete that distance. It is given as:

Here, d is the total distance covered by Carl and t is the total time he took to complete the total distance d.

Substituting the values in the above equation, we get:

Now, the average velocity of an object is defined as the displacement of an object divided by the total time it took to displace from its initial position.

As Carl runs one complete lap around an outdoor track, after one round he returns to his original initial position from where he had started running. Thus, the displacement D of the Carl will be zero.

Thus, D = 0 m

The average velocity V is calculated as:

Substituting the values in the above equation, we get:

Final answer:

Thus, the average speed of Carl is 4 m/s and his average velocity is 0 m/s.

Absorption of light or radiation occurs when the incident ray strikes the surface at an oblique angle rather than a right angle. When light or radiation strikes a surface at a right angle (perpendicular to the surface), it is more likely to be reflected or transmitted rather than absorbed.

When light strikes a surface at an oblique angle, it has a higher chance of being absorbed by the material. The absorption process involves the transfer of energy from the incident light to the atoms or molecules of the material, causing them to vibrate or undergo electronic transitions, which leads to an increase in the internal energy of the material. It's important to note that the amount of absorption depends on various factors such as the properties of the material, the wavelength of the incident light, and the angle of incidence. Materials have different absorption characteristics at different wavelengths, and the angle of incidence can affect the path length and the interaction of light with the material, influencing the absorption process.

Explanation:

The tendency of an atom to gain or lose electrons in a chemical reaction are given by its electronegativity and electropositivity respectively

Electronegativity is a measure of an atom's capacity to attract electrons from neighboring particles, with atoms that are more likely to gain an electron, being described as having a higher electronegativity

Electronegativity increases across the period with increasing number of valence electrons, therefore, elements with five, six, or seven electrons, which are located on the far right of the periodic table are said to have higher electronegativity and therefore more likely to gain electrons in a chemical reaction

Electropositivity is the quantification or measure of an element to donate or give electrons and become positively charged ions in a chemical reaction

The fewer the number of valence electrons an element has, the more likely the element will undergo a reaction by donating the valence electrons to a more electronegative atom and become positively charged

Electropositivity decreases across the period and therefore, elements with one, two, or three valence electrons which are located in groups I, II, and III, are more likely to lose electrons in a chemical reaction

Explanation:

To achieve critical damping, the mass that should be used with the spring and damping constant is approximately 3 kg.

In the case of critical damping, the damping force is equal to the spring force at the equilibrium position. The damping force is given by the damping constant multiplied by the velocity. Since the spring is stretched 2 meters beyond its natural length and released with zero velocity, the velocity at equilibrium is zero. Thus, the damping force at equilibrium is zero.

At equilibrium, the spring force is equal to the force required to hold the spring stretched 1 meter beyond its natural length, which is 4 newtons. The spring force is given by Hooke's Law: F = kx, where F is the force, k is the spring constant, and x is the displacement from the equilibrium position. In this case, the displacement x is 1 meter, and the force F is 4 newtons.

Using the formula F = kx, we can solve for the spring constant: k = F/x = 4 N / 1 m = 4 N/m.

For critical damping, the damping constant is given by the formula c = 2 * sqrt(m * k), where c is the damping constant and m is the mass. Rearranging the formula, we can solve for m: m = (c^2) / (4 * k). Substituting the values c = 2 kg/s and k = 4 N/m, we find that the mass required for critical damping is m = (2^2) / (4 * 4) = 1/4 kg = 0.25 kg.

Therefore, the mass that would produce critical damping in this scenario is approximately 0.25 kg or 3 kg (rounded to the nearest whole number).
