We can actually deduce here that if one end of a heavy rope is attached to one end of a lightweight rope, a wave can move from the heavy rope into the lighter one. What happens to the frequency that it increases.

Thus, option A. It increases is the answer.

<h3>What is frequency?</h3>

Frequency is actually known to be the amount or number of waves that passes a fixed point per unit time. In physics, frequency is also known as the number of cycles or vibrations per unit time.

When the wave move from the heavy rope into the lighter one, the wave speed will definitely increase. This is because when a wave is created from the end of the heavy rope, the frequency will start small and then increases as it gets to the end of the lighter rope.

For the PE formula, why is the height required for calculations? Why do we need to know the height in order to determine PE? *
Fudgin [204]

Answer:

Answer in Explanation

Explanation:

Whenever we talk about the gravitational potential energy, it means the energy stored in a body due to its position in the gravitational field. Now, we know that in the gravitational field the work is only done when the body moves vertically. If the body moves horizontally on the same surface in the Earth's Gravitational Field, then the work done on the body is considered to be zero. Hence, the work done or the energy stored in the object while in the gravitational field is only possible if it moves vertically. This vertical distance is referred to as height. <u>This is the main reason why we require height in the P.E formula and calculations.</u>

The derivation of this formula is as follows:

Work = Force * Displacement

For gravitational potential energy:

Work = P.E

Force = Weight = mg

Displacement = Vertical Displacement = Height = h

Therefore,

P.E = mgh

The greatest ocean depths on the Earth are found in the Marianas Trench near the Philippines. Calculate the pressure (in atm) du
frozen [14]

Answer:

P = 103867260 atm

Explanation:

The pressure at the bottom of any liquid column is equal to product of density of the liquid , gravitational acceleration constant (g) and height of the water column

Thus, P = \rho*g*h

Substituting the given values, we get -

P = 1029 kg/m3 * 9.8 m/s^2  *10.3 *1000 meters

P = 103867260 atm
