find the mass of a ball on a roof 30 meters high, if the ball's gravitational potential energy is 58.8 joules
Sidana [21]
We are given the gravitational potential energy and the height of the ball and is asked in the problem to determine the mass of the ball. the formula to be followed is PE = mgh where g is the gravitational acceleration equal to 9.81 m/s^2. substituting, 58.8 J = m*9.8 m/s^2 * 30 m; m = 0.2 kg.

The slope of this graph is _____.
Artemon [7]

The slope of the illustrated graph would give us the velocity of the object whose motion is plotted in the graph.

<h3>What is velocity?</h3>

Velocity refers to the rate of movement of objects along a particular line. In other words, the velocity of an object is the speed of the object in a specific direction relative to time.

Also, velocity = displacement/time.

In the graph, the slope is given by: Δy/Δx = displacement/time = velocity.

How are a wave's energy and the wave's amplitude related?
dem82 [27]
Answer:
Energy is proportional to the square of the amplitude

Explanation:
The energy of a certain wave is defined using its magnitude.
The two quantities are related directly. This means that as the amplitude of the wave increases, its energy increases and vice versa.

Energy is directly proportional to the square of the magnitude of the wave. This means that:
If we have new amplitude = 2 * old amplitude
We will have new energy = (2)² * old energy = 4 * old energy

Hope this helps :)
