a) Answer: On the equator, the Circle of Illumination divides the earth into two equal parts, with each part receiving 12 hours of daylight and 12 hours of darkness.

The equator receives an equal day and night (12 hours each) regardless of the day of the year due to the Circle of Illumination, which is a line that separates the day side of the earth from the night side of the earth. The Circle of Illumination separates the sunlit and dark sides of the earth. The earth's axis is at a 23.5-degree angle to the plane of its orbit around the sun, causing different latitudes to receive different amounts of sunlight throughout the year. On the equator, the Circle of Illumination divides the earth into two equal parts, with each part receiving 12 hours of daylight and 12 hours of darkness.

b)  Answer: The earth's axis is tilted at 23.5°, and during the December solstice, the North Pole is tilted away from the sun, causing the Arctic Circle and areas beyond it to experience a full day of daylight because the sun is above the horizon for 24 hours.

On December 22nd, between the latitudes of the Tropic of Cancer (23.5°N) and the Arctic Circle (66.5°N), 24 hours of daylight is experienced.

The femur can withstand a compression of about 4.1945 mm before breaking.

We can use the formula for compressive stress to calculate the amount of compression that the femur bone can withstand before breaking:

Stress = Force / Area

where the force is the force applied to the bone and the area is the cross-sectional area of the bone.

To find the cross-sectional area of the femur bone, we can assume that it has a circular cross-section and use the formula:

Area = πr^2

where r is the radius of the cross-section.

Since the length of the femur bone is 0.5 m, we can assume that the cross-sectional area remains constant along its length.

Let's assume that the force required to break the bone is the maximum compressive stress that it can withstand, which is 1.51 × 10^8 Pa. We can rearrange the stress formula to solve for the force.

We can use the equation for strain under compression:

strain = stress / Young's modulus

where stress is the maximum stress the bone can withstand before breaking, and Young's modulus is a measure of the stiffness of the material. The strain is a measure of how much the bone compresses under stress.

To find the compression distance, we can rearrange this equation to solve for the compression distance:

compression distance = strain x original length

where the original length is the length of the bone before compression

Substituting the given values:

stress = 1.51 × 10^8 Pa

Young's modulus = 1.8 × 10^10 Pa

original length = 0.5 m

First, we can calculate the strain:

strain = stress / Young's modulus = (1.51 × 10^8 Pa) / (1.8 × 10^10 Pa) ≈ 0.008389

Next, we can calculate the compression distance:

compression distance = strain x original length = (0.008389) x (0.5 m) = 0.0041945 m

Finally, we can convert the result to millimeters:

compression distance = 0.0041945 m x (1000 mm/m) = 4.1945 mm

Therefore, the femur can withstand a compression of about 4.1945 mm before breaking using Stress = Force / Area

Explanation:

If an equation is already balanced there is no need to provide information of that.

The wave speed of a transverse wave traveling down a rope can be determined using the formula v = √(T/μ), where v represents the wave speed, T is the tension force, and μ is the linear mass density of the rope.

To find the linear mass density, we divide the mass of the rope (m) by its length (l): μ = m/l.

Given that the mass of the rope is 10 kg and the length is 50 m, the linear mass density is μ = 10 kg / 50 m = 0.2 kg/m.

Substituting the values of T = 2000 N and μ = 0.2 kg/m into the formula for wave speed, we have:

v = √(2000 N / 0.2 kg/m)

  = √(10000 m^2/s^2 / kg/m)

  = √(10000 m^2/s^2) (canceling out the units)

  = 100 m/s

Therefore, the wave speed of the transverse wave traveling down the rope is 100 m/s.

To determine the torque and power required to rotate the inner cylinder at 150 rpm, we can use the following formula:  T = F * r where, T is torque, F is force, and r is the distance from the axis of rotation to the point where the force is applied.The explanation is as follows:

The space between two 6-in.-long concentric cylinders is filled with glycerin. The inner cylinder has a radius of 3 in. and the gap width between cylinders is 0.1 in. The outer cylinder is fixed. The velocity distribution in the gap is linear.Since the problem states that the velocity distribution in the gap is linear, we can assume that the shear stress, τ, between the inner and outer cylinders varies linearly as well.

The shear stress, τ, is defined by the formula:  τ = μ * dv / dywhere, μ is the dynamic viscosity, dv/dy is the velocity gradient in the y direction.Since the velocity is linear, the velocity gradient dv/dy is constant and equal to v0 / d where v0 is the velocity of the inner cylinder and d is the gap width between the cylinders. Substituting these values, we get:  dv / dy = v0 / dThe shear stress is zero at the inner cylinder and is equal to τ0 at the outer cylinder. Thus, we can write:  τ = τ0 * (y / d)where, y is the distance from the inner cylinder.We can now calculate the force acting on the inner cylinder by integrating the shear stress over the area of contact between the cylinders. This area is given by:  A = 2πrhwhere, r is the radius of the inner cylinder, and h is the gap width between the cylinders.Substituting the values, we get:  A = 2π(3 in.)(0.1 in.) = 0.6π in²The force can be calculated as follows:  F = τ * A = τ0 * (y / d) * 0.6πwhere, y is the distance from the inner cylinder. Substituting the values, we get:  F = τ0 * (y / d) * 0.6πNow, we can calculate the torque required to rotate the inner cylinder at 150 rpm. The torque is given by:  T = F * rwhere, r is the radius of the inner cylinder.Substituting the values, we get:  T = τ0 * (y / d) * 0.6π * rThe power required to rotate the inner cylinder at 150 rpm can be calculated using the following formula:  P = 2πNT / 60where, N is the rotational speed in rpm, and T is the torque in lb-in.Substituting the values, we get:  P = 2π(150 rpm)(T) / 60where, T is in lb-in.

Star will take t_fade = 0.1 * M / L for the burst to fade to 10% of its original luminosity.

The main-sequence lifetime of a star depends on its mass, and can be approximated by the formula:

t_MS = M / L

where t_MS is the main-sequence lifetime in years, M is the mass of the star in solar masses, and L is the luminosity of the star in solar luminosities.

A reasonable estimate is that the burst releases about 10% of the star's total energy, so the time it takes for the star to fade to 10% of its original luminosity is roughly:

t_fade = 0.1 * t_MS

t_fade = 0.1 * M / L

Note that this is just a rough estimate, and the actual time it takes for a star to fade after a burst may be shorter or longer depending on the specifics of the burst and the star.

The intensity of sound is inversely proportional to the square of the distance from the source. The intensity of sound at 4 m away from the source is approximately \(0.993W/m^{2}\) (watts per square meter).

The intensity of sound is defined as the power per unit area. According to the inverse square law for sound propagation, the intensity of sound is inversely proportional to the square of the distance from the source. Mathematically, it can be expressed as

\(I=P/(4\pi r^{2})\)

where I is the intensity, P is the power, and r is the distance from the source.

Given that the power of sound at the source outlet is 100 W and the distance from the source is 4 m, we can substitute these values into the formula. Thus, we have

\(I = 100 W / (4\pi (4 m)^2)\)

In vaccum, this velocity is c = 3x10^8 m/s.

And we know that:

distance = velocity*time

Now, if some object (like a star ) is really far away, the light that comes from that star may take years to reach the Earth.

This means that the images that the astronomers see today, actually happened years and years ago (So the night sky is like a picture of the "past" of the universe)

Also, for example, if an astronomer sees some particular thing, he can apply a model (a "simplification" of some phenomena that is used to simplify it an explain it) and with the model, the scientist can infer the information of the given thing some time before it was seen.

The astronomers could know what was happening inside galaxies way back then by the fact that;

they examine the spectra of galaxies (or the overall colors of galaxies) with the highest redshifts they can find

Astronomers Measure the wavelength of the light that is stretched, so the light is seen as 'shifted' towards the red part of the spectrum by using spectroscopy. This measure is also called redshift.

This invokes a ray of light through a triangular prism that splits the light into various components known as spectrum.

Destructive interference: path diff = half wavelength. Film thickness: t = (m * λ) / (4 * n), where t is thickness, m is interference order, λ is film's wavelength (λ = λ_air / n), n is refractive index.

Destructive interference occurs when the path difference between the reflected waves from the two surfaces of the magnesium fluoride film is equal to half the wavelength of the incident light. Mathematically, this can be expressed as 2t = (m + 1/2) * λ, where t is the thickness of the film, m is an integer representing the order of the interference, and λ is the wavelength of light in the film.

To calculate the minimum thickness required for destructive interference at a specific wavelength, we can rearrange the equation to t = (m * λ) / (4 * n), where n is the refractive index of the film. In this case, the refractive index of magnesium fluoride is 1.3.

For yellow-green light with a wavelength of 540 nm, we can substitute λ = 540 nm and n = 1.3 into the formula. Assuming we are looking at the first-order (m = 1) destructive interference, the minimum thickness required can be calculated as follows:

t = (1 * 540 nm) / (4 * 1.3) ≈ 104.62 nm
