Answer:

well, because of the moon!

Explanation:

you see, the moon is what controls the waves. waves are most commonly caused by wind. wind-driven waves, or surface waves, are created by the friction between wind and surface water. as wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. the gravitational pull of the sun and moon on the earth also causes waves. so when the gravitation pull is weak, it creates the shorter wavelengths. without a stong pull, they don't go as far. when the pull is strong, the waves with longer wavelengths go further.

Answer:

The question does not state how the answer is to be entered. I would use 10% because that is most common.

Explanation:

You are using 300 J of energy to get 30 J of light energy. The fact that you can account for the left over energy is not relevant.

Efficiency = Work Out / Work In

Efficiency = 30 J / 300 J  = 0.1

If you need this as a %, you can multiply by 100

Efficiency = 0.1 * 100 = 10%

When a rolling yo-yo falls to the bottom of its cord, its rotation as it climbs back up the cord will be : 4. reversed rotation due to the rebound.

As the yo-yo reaches the bottom, it experiences a change in direction and rebounds upwards. This change potential energy is converted into kinetic energy.

However, due to the conservation of angular momentum, the rotation of the yo-yo is reversed when it changes its direction of motion. This means that if the yo-yo was spinning clockwise when it fell, it will spin counterclockwise when it climbs back up the cord.

This reversal of rotation is due to the yo-yo's angular momentum remaining constant, but its direction changing as it changes direction of motion.

The time required for the pressure to decrease to 10⁻⁴ mmHg is approximately 0.7 x 10⁵ s.

The rate at which water vapor molecules hit the cold patch and condense can be calculated using the kinetic theory of gases.

The number of water vapor molecules per unit volume in the bulb can be approximated by the ideal gas law:

PV = nRT

where,

P = pressure,

V = volume,

n = number of molecules,

R = gas constant, and

T = temperature.

Solving for n/V, we get:

n/V = P/RT

Given, P = 0.1 mmHg = 0.1/760 atm

           T = 300 K

Therefore, number of water vapor molecules per unit volume is:

n/V = (0.1/760 atm) / [(8.31 J/mol K) (300 K)]

      = 5.28 × 10⁻⁸ mol/m³

      = 5.28 × 10⁻⁸ * (6.02 x 10²³ molecules/mol)

      = 3.18 ×10¹⁶ molecules/m³

The rate at which water vapor molecules effuse through the cold patch can be approximated using Graham's law of effusion:

\(\frac{r_{1}}{r_{2}} =\sqrt{\frac{M_{2} }{M_{1} } }\)

where rate1 and rate2 are the rates at which two gases effuse through a small hole, and M1 and M2 are their molecular masses.

In given condition,

we can treat the water vapor molecules as effusing through the cold patch into a vacuum,

∴ rate = A* (1/4) * (n/V) * √(8kT/πm)

where, A is the area of the cold patch, k is the Boltzmann constant, T is the temperature, and m is the mass of a water molecule.

Substituting the values, we get:

rate = 1 × 10⁻⁴ * (1/4) * (3.18×10¹⁶) * √[(8 * 1.38x10⁻²³ * 300) / (π * 3.01x10⁻²⁶)]

      = 1 × 10⁻⁴ * (1/4) * (3.18×10¹⁶) * 0.59

      = 4.69 x 10¹³ molecules/s

This is the rate at which water vapor molecules are removed from the bulb. The time required for the pressure to decrease to 10^-4 mmHg can be approximated by assuming that the pressure decreases exponentially with time:

P(t) = P₀ exp(-kt)

where P₀ is the initial pressure, k is a constant, and t is the time.

The constant k can be calculated from the rate:

k = rate / N

where N is the number of water molecules per unit volume.

Substituting the values, we get:

k = 4.69 x 10¹³ molecules/s / 3.18 ×10¹⁶ molecules/m³

k = 1.47x 10⁻³ s⁻¹

The time required for the pressure to decrease to 10⁻⁴ mmHg can then be calculated:

10⁻⁴ mmHg = 0.1 mmHg  exp(-1.47x 10⁻³ * t)

∴ t = 0.7 x 10⁵ s

Therefore, the time required for the pressure to decrease to 10⁻⁴ mmHg is approximately 0.7 x 10⁵ s.

Regulating the amount of light involves controlling the brightness, while condensing the light refers to focusing and concentrating the light rays.

In physics, regulating the amount of light and condensing the light are two distinct concepts.

Regulating the amount of light involves controlling the intensity or brightness of light. This can be achieved through various methods, such as using dimmer switches or adjustable light sources. By increasing or decreasing the amount of electrical current flowing through a light source, the brightness can be adjusted accordingly. For example, dimmer switches in homes allow users to control the brightness of their lights.

Condensing the light refers to focusing or concentrating the light rays. This is often accomplished using optical devices like lenses or mirrors. These devices manipulate the path of light, causing the rays to converge into a smaller area. As a result, the light becomes more concentrated and focused. This concept is widely used in applications such as photography, where lenses are used to focus light onto the camera sensor.

While regulating the amount of light is about controlling the brightness, condensing the light is about focusing and concentrating the light rays.
