Answer:
1. The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves.
2. potential energy
3. Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
4. Refraction is the bending of light
5. Density uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). Density is defined as mass per unit volume.

Answer:
a.
is the time after which the two stone hit the water surface.
b. 
c.
& 
Explanation:
Given:
- height of the cliff,

- time gap between the projection of stones,

- initial velocity of first stone,
Here positive sign means that the stone is thrown vertically downward in the direction of gravity.
a.
Using equation of motion:


is the time after which the two stone hit the water surface.
b.
using the equation of motion for second stone:



c.
Final velocity of the stone at the instant of touching the water surface:



&
