Answer:

Among those two medium, light would travel faster in the one with a reflection angle of \(32^{\circ}\) (when light enters from the air.)

Explanation:

Let \(v_{1}\) denote the speed of light in the first medium. Let \(v_{\text{air}}\) denote the speed of light in the air. Assume that the light entered the boundary at an angle of \(\theta_{1}\) to the normal and exited with an angle of \(\theta_{\text{air}}\). By Snell's Law, the sine of \(\theta_{1}\!\) and \(\theta_{\text{air}}\!\) would be proportional to the speed of light in the corresponding medium. In other words:

\(\displaystyle \frac{v_{1}}{v_{\text{air}}} = \frac{\sin(\theta_{1})}{\sin(\theta_{\text{air}})}\).

When light enters a boundary at the critical angle \(\theta_{c}\), total internal reflection would happen. It would appear as if the angle of refraction is now \(90^{\circ}\). (in this case, \(\theta_{\text{air}} = 90^{\circ}\).)

Substitute this value into the Snell's Law equation:

\(\begin{aligned}\frac{v_{1}}{v_{\text{air}}} &= \frac{\sin(\theta_{1})}{\sin(\theta_{\text{air}})} \\ &= \frac{\sin(\theta_{c})}{\sin(90^{\circ})} \\ &= \sin(\theta_{c})\end{aligned}\).

Rearrange to obtain an expression for the speed of light in the first medium:

\(v_{1} = v_{\text{air}} \cdot \sin(\theta_{1})\).

The speed of light in a medium (with the speed of light slower than that in the air) would be proportional to the critical angle at the boundary between this medium and the air.

For \(0 < \theta < 90^{\circ}\), \(\sin(\theta)\) is monotonically increasing with respect to \(\theta\). In other words, for \(\!\theta\) in that range, the value of \(\sin(\theta)\!\) increases as the value of \(\theta\!\) increases.

Therefore, compared to the medium in this question with \(\theta_{c} = 27^{\circ}\), the medium with the larger critical angle \(\theta_{c} = 32^{\circ}\) would have a larger \(\sin(\theta_{c})\). such that light would travel faster in that medium.

What does density mean?

How tightly the particles of a solid, liquid, or gas are packed is described by its density. The amount of mass per unit volume is known as density.

The density of a pure substance is equal to its mass concentration in numbers. Density varies widely among materials and may be important in relation to packaging, purity, and buoyancy. A substance's density changes as a function of pressure and temperature. For solids and liquids, this variance is often minimal, but for gases, it is much more pronounced. An object's density increases as pressure is applied, which causes the object's volume to decrease.

Density is given 13.6g/cm^3

The initial speed of the bullet is 200 m/s.

Conservation of momentum is a law of physics which states that the total momentum of a system remains constant over time. This means that when two or more objects interact, the total momentum of the system remains the same before and after the interaction. The law of conservation of momentum is applicable to both isolated systems and systems that interact with external forces. It is an important concept in a variety of applications ranging from collisions of particles to the motion of galaxies. Conservation of momentum also plays an important role in the field of quantum mechanics.

The initial speed of the bullet can be calculated using the conservation of momentum equation:
m₁v₁ + m₂v₂ = m₁v′₁ + m₂v′₂

where m₁ is the mass of the bullet, v₁ is the initial speed of the bullet, m₂ is the mass of the pendulum, v₂ is the initial speed of the pendulum, v′₁ is the final speed of the bullet, and v′₂ is the final speed of the pendulum.
In this problem, m₁ = 7.0 g, v₁ = ?, m₂ = 1.5 kg, v₂ = 0 m/s, v′₁ = 200 m/s, and v′₁ = 0 m/s.
Substituting this into the equation, we get:
7.0 g x v₁ + (1.5 kg)(0 m/s) = 7.0 g(200 m/s) + (1.5 kg)(0 m/s)
Solving for v₁, we get:
v₁ = 200 m/s
Therefore, the initial speed of the bullet is 200 m/s.

Answer:

15,115 J of the total energy is transformed to thermal energy during the game.

Explanation:

From the law of conservation of energy, initial energy of the closed system E = final energy of closed system , E'

E = E'.

Let ME = initial mechanical energy of the system = 16,250 J and U = initial internal energy of the system and ME' = Final mechanical energy of the system = 1,135 J and U' = Final internal energy of the system.

So E = ME + U and E' = ME' + U'

We now find U and U'

Substituting E, ME, E' and ME' into the equations, we have

E = ME + U

17,125 J = 16,250 J + U

U = 17,125 J - 16,250 J

U = 875 J

E' = ME' + U'

17,125 J = 1,135 J + U'

U' = 17,125 J - 1,135 J

U' = 15,990 J.

The change in internal energy is also the change in thermal energy. So,

ΔU = U' - U

ΔU = 15,990 J - 875 J

ΔU = 15,115 J

So 15,115 J of the total energy is transformed to thermal energy during the game.

During a solar eclipse, the Moon will be positioned between the Earth and the Sun, blocking the Sun's light from reaching the Earth. Based on the diagram provided, the position of the Moon during a solar eclipse would be at position Z. This is because in this position, the Moon is directly aligned with the Earth and the Sun, creating a shadow that falls on the Earth, resulting in a solar eclipse.

It's important to note that a solar eclipse is a rare occurrence and can only happen during a New Moon phase, where the Moon is positioned between the Earth and the Sun. In contrast, a lunar eclipse occurs when the Earth is positioned between the Sun and the Moon, causing the Earth's shadow to fall on the Moon.

In the second diagram, the four coastline locations (A, B, C, and D) have different positions relative to the Moon and the Sun. The diagram shows the relative positions during high tide and low tide, indicating the effects of the Moon's gravitational pull on ocean tides.

Coastline location A experiences a high tide because it is closest to the Moon, which has a greater gravitational pull on the water. Coastline location B experiences a low tide because it is on the opposite side of the Earth from the Moon, where the Moon's gravitational pull is weakest. Coastline location C experiences another high tide because it is on the side of the Earth facing away from the Moon, where the water is also being pulled towards the Moon. Lastly, coastline location D experiences a low tide because it is in a position where the gravitational pull of the Moon and the Sun is canceling out, resulting in less of a tidal effect.

In summary, understanding the position of the Moon and its effects on the Earth is important in predicting natural phenomena such as eclipses and tides.

B. A large current forms, drops to zero, then a smaller current forms in the opposite direction

Explanation:

The results of Lionel observation about electromagnetic induction is as follows:

In the first step, a large current will form because of the fast or quick movement of the magnet into the right end of a solenoid that generates a  induces emf.

In the second step, the magnet was in rest position for 3 s so the current drops to zero because according to Faraday's law, no voltage will be generated if the magnet held stationary and no voltage means no current.

In the third step, smaller current forms in the opposite direction as the magnet is slowly moving away from the solenoid generating a smaller voltage.

If an object's tangential velocity at closest approach to Earth is less than the circular velocity, it will not have enough speed to maintain a stable orbit. Instead, it will follow a highly elliptical or hyperbolic trajectory, eventually moving away from the Earth.

When an object orbits the Earth, it needs to have a specific velocity known as the circular velocity to counteract the gravitational pull. The circular velocity depends on the mass of the Earth and the object's distance from its center. If the object's tangential velocity at closest approach is less than the circular velocity, it means that the object is not moving fast enough to overcome Earth's gravitational pull.

As a result, the object will follow an elliptical or hyperbolic trajectory rather than a stable orbit. In an elliptical orbit, the object will move away from Earth, reaching its farthest point (apoapsis) before returning to the closest point (periapsis). This path is repeated in a regular cycle.

On the other hand, if the object's velocity is high enough to surpass the escape velocity, it will follow a hyperbolic trajectory, which means it will move away from Earth indefinitely. This occurs when the object's velocity is sufficient to overcome the gravitational pull of the Earth entirely.

In either case, if an object's tangential velocity at closest approach is less than the circular velocity, it will not remain in a stable orbit and will either move along an elliptical path or escape the Earth's gravitational pull.

A white dwarf remains stable in size due to electron degeneracy pressure, which prevents its atoms from collapsing further despite the absence of nuclear fusion reactions.

A white dwarf is a remnant of a low to medium mass star that has exhausted its nuclear fuel and undergone gravitational collapse. As the star's core collapses, its electrons become tightly packed together, leading to electron degeneracy pressure that opposes further compression. This results in a stable size for the white dwarf, where the inward force of gravity is balanced by the outward force of electron degeneracy pressure. Since there are no nuclear fusion reactions to generate heat, the white dwarf eventually cools and dims over time, becoming a cold black dwarf.

Only a small portion of the sun's initial energy strikes the earth's surface since the majority of it is absorbed as it travels through the atmosphere, mostly as infrared radiation.

Heat is produced as a result of infrared radiation's ability to shift molecular bonds, which releases energy. Even ice cubes, which are commonplace items, give out thermal energy. Thermal energy is released more readily by hotter objects. The thermal signature, also known as the heat signature, is the energy that an object emits.

The so-called greenhouse effect (see The greenhouse effect of the atmosphere above) depends on infrared radiation, which affects the Earth's thermal radiation budget globally and almost all biospheric activity. Infrared radiation also plays a significant role in heat transmission.
