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.

An elephant lifts 7 large logs from the ground to a container 5 meters above the ground as part of a zoo demonstration. The elep

Alisiya [41]

The work done by the elephant to lift one log is the force multiplied by the height at which the log has been lifted:
$W=Fh=250 N \cdot 5 m=1250 J$
And so, the total work done to lift the 7 logs is 7 times the work done to lift each log:
$W_t = 7 W=7 \cdot 1250 N=8750 J$
