if two successive wave troughs are 120 m apart, what is the approximate depth of the wave base?

The capacitance of the RC circuit can be calculated by dividing the time constant by the total resistance.

The time constant (τ) of an RC circuit is given by the product of resistance (R) and capacitance (C), τ = RC. In this case, the time constant is given as 6.27 seconds. The total resistance in the circuit is 123.9 kilohms (123.9 kΩ).

To find the capacitance, we rearrange the formula to solve for C: C = τ/R. Substituting the given values, we have C = 6.27 s / 123.9 kΩ. Simplifying the units, 123.9 kΩ can be written as 123,900 Ω. Therefore, the capacitance of the circuit is equal to 6.27 s / 123,900 Ω, expressed in farads (F).

Answer:

5.03×10¯⁷ N

Explanation:

From the question given above, the following data were obtained:

Mass of the person (M₁) = 55 Kg

Mass of the car (M₂) = 1234 Kg

Distance apart (r) = 3 m

Gravitational constant (G) = 6.673×10¯¹¹ Nm²/Kg²

Force (F) =?

The force between the person and his car can be obtained as follow:

F = GM₁M₂ / r²

F = 6.673×10¯¹¹ × 55 × 1234 / 3²

F = 6.673×10¯¹¹ × 67870/ 9

F = 5.03×10¯⁷ N

Thus, the force between the person and his car is 5.03×10¯⁷ N

Answer:

The celestial sphere turns once around each day because...

the planet on which we live is rotating

Explanation:

Earth is constantly rotating which causes the celestial sphere to rotate as well.

The velocity of the two objects after the collision is 0.1535 m/s in south direction.

The law of conservation of momentum asserts that, unless an external force is applied, the total momentum of two or more bodies operating upon one another in an isolated system remains constant.

From the law of conservation of momentum, it can be written that:

Total initial momentum = total final momentum

19 kg × 4.2 m/s + 24 kg × (-3.6) m/s = (19 kg + 24 kg)× v

v = [19 kg × 4.2 m/s + 24 kg × (-3.6) m/s] ÷  (19 kg + 24 kg)

v = - 0.1535 m/s

Hence,  the velocity of the two objects after the collision is 0.1535 m/s in south direction.

Answer:

Explanation:

By changing its kinetic energy, a particle's speed rises by a factor of 9 when the speed of the particle increases by a factor of 3 so K₂/K₁ = 9.

As per the question given,  

The kinetic energy of a particle is given by the formula:

K = (1/2)mv²

where m is the mass of the particle and v is its velocity.

If the speed of the particle increases by a factor of 3, then the new velocity is 3 times the initial velocity:

v₂ = 3v₁

The new kinetic energy is given by:

K₂ = (1/2)m(3v₁)² = 9(1/2)mv₁² = 9K₁

where K₁ is the initial kinetic energy.

Therefore, the kinetic energy changes by a factor of 9 when the speed of the particle increases by a factor of 3.

In other words: K₂/K₁ = 9

Perfect inelasticity governs the collision. Both athletes go north at a speed of 2 m/s just after the tackle. Prior to the tackle, the 90 kg athlete was moving at a speed of 6 m/s south.

In an inelastic collision, momentum is preserved, hence we may apply the equation: (m1 * v1) plus (m2 * v2) equals (m1 + m2) * vf.

The following is the result of substituting the above values: (90 kg * v1) + (120 kg * (-4 m/s)) = (90 kg + 120 kg) * 2 m/s

When we simplify the equation, we obtain: 90v1 - 480 = 210 90v1 = 690\sv1 = 7.67 m/s They move at a speed of -4 m/s. As a result, the player weighing 90 kg was moving at the following speed right before the tackle: south

Nevertheless, the question specifically asks for the northward velocity shortly before the tackle, therefore we must adjust the sign:

North: v1 = -11.67 m/s plus 2 m/s equals -9.67 m/s

Prior to the tackle, the 90 kg athlete was moving at a speed of 6 m/s south.

Assuming that the man is standing still on a flat, horizontal surface and neglecting air resistance, the normal force produced by the ground upwards on the leg would be equal in magnitude to the weight of the man, which is given as approximately 84 kg.

Therefore, the normal force being produced by the ground upwards on the leg would be approximately 84 kg multiplied by the acceleration due to gravity (9.81 m/s^2), which gives a value of approximately 823.44 N (Newtons).

So the normal force being produced by the ground upwards on the leg is approximately 823.44 N.

The skater moves at a 10 m/s speed. The right answer is A.

We must examine the forces operating on the skater in order to calculate their speed. The horizontal force applied to the ground creates the centripetal force, which is pointed in the direction of the circular path's center.

The centripetal force is calculated using the formula F = (mv2) / r, where m is the skater's mass, v is the speed, and r is the circle's radius.

We may convert the skater's horizontal force of 1125 N to the centripetal force as follows:

1125 N = (45 kg * v^2) / 4 m.

We rearrange the equation to find v:

1125 N * 4 m = 45 kg * v^2.

4500 N*m = 45 kg * v^2.

If you multiply both sides of the equation by 45 kg, you get:

100 N*m = v^2.

Taking the square root of both sides gives:

v = 10 m/s.

Therefore, the skater's speed is 10 m/s. The correct option is A.

An ensemble forecast is considered robust when the following conditions are met:

1) The individual members of the ensemble produce similar forecasts.

This means that the different members of the ensemble are in agreement with each other in terms of the predicted weather pattern, temperature, or other relevant meteorological variables.

2) The ensemble mean is a good predictor of the actual outcome.

The ensemble mean is calculated by averaging the forecasts from all the members of the ensemble.

If the ensemble mean is close to the observed value, it suggests that the ensemble forecast is reliable.

4) The ensemble spread is not too large.

The ensemble spread is a measure of the variability of the different members of the ensemble.

If the spread is too large, it indicates that the model is uncertain about the forecast, and the confidence in the forecast is reduced.

However, if the spread is too small, it can indicate that the model is not capturing all the sources of uncertainty, and the forecast may be overly confident.

5) The ensemble has a good track record.

A model that has produced accurate forecasts in the past is more likely to produce reliable forecasts in the future.

Therefore, a robust ensemble forecast is one that has a proven track record of accuracy and reliability.

In summary, an ensemble forecast is considered robust when the individual members of the ensemble produce similar forecasts.

The ensemble mean is a good predictor of the actual outcome, the ensemble spread is not too large, and the ensemble has a good track record of accuracy and reliability.

Gravity causes an object to fall toward the ground more quickly the longer it is in free fall. In reality, an object's velocity increases by 9.8 m/s, and by the time it starts to fall, it has already reached 9.8 m/s.

All matter is impacted by a force called gravity in the universe. Any two non-zero mass objects or particles will gravitationally gravitate toward one another. Gravity has an impact on objects of all sizes, from subatomic particles to galaxy clusters.

Speed after 2 seconds = 40m/s

Since falling causes velocity to increase by 9.8m/s,

Speed 5 seconds after the jump = 40 + (3 * 9.8)

                                                      = 69.4 m/s

When an object is moving, its velocity serves as a measure of how quickly its location is changing as it is perceived from a given point of view and as time is measured using a specific unit of measurement.

The possible energies of the emitted photons are 1 eV.

The possible energies of the photons emitted from a collection of objects with all five states occupied can be determined by the energy differences between the occupied states. If all five states are occupied, the energy differences between the states can be calculated by subtracting the energy of the lower state from the energy of the higher state.

Considering the given energy options:

1 eV, 2 eV, 3 eV, 4 eV, 5 eV

The possible energy differences are:

2 eV - 1 eV = 1 eV

3 eV - 2 eV = 1 eV

4 eV - 3 eV = 1 eV

5 eV - 4 eV = 1 eV

Therefore, the possible energies of the emitted photons are 1 eV.

It's important to note that the remaining energy options (6 eV to 20 eV) do not have corresponding energy differences of 1 eV between adjacent states. Hence, these options are not valid energies for the emitted photons in this scenario.
