Answer:
decreases, increases, minimum (zero)
Explanation:
Kinetic energy of a body is directly proportional to the square of velocity of the body and the potential energy is directly proportional to the height of the body at which it is placed.
The formula for the kinetic energy is
K = 1/2 m v^2
The formula for the potential energy is
U = m g h
As the body goes up its kinetic energy decreases as the velocity of the object decreases.
As the body goes up the potential energy increases as the height increases.
At the top most point, the velocity of teh object is zero, so the kinetic energy at the top is zero.
The largest distance moved by a particle of a vibrating body from its equilibrium position is called amplitude. Wave B has higher energy because wave it has a higher amplitude.
<h3>What is the amplitude of a wave?</h3>
The largest distance moved by the particles on either side of the mean position is the amplitude of a wave.
The maximum height of either crest or trough from its equilibrium position is called amplitude.
Hence Wave B has higher energy because it has a higher amplitude.

The temperature rises during boiling.
Answer:
94.28 cm
Explanation:
The formula for elastic potential energy is given as;
PEel = 1/2 *k*x² where x is the displacement, k is the spring constant
Given
PEel = 110 J, k= 350 N/m then find x
PEel = 1/2 *k*x²
110 = 1/2 * 350 * x²
110 = 175 x²
110/175 = x²
0.6286=x²
√0.6286 =x
0.7928 m = x
79.28 cm = x
New length of spring = 15 cm + 79.28 cm = 94.28 cm
