Answer A) the watermelon has more inertia so it takes more force to move it.
Ep is gravitational potential energy
m is mass (kg)
g is gravitational field strength (N/kg)
h is height (m)
Ep= mgh
= 80kg*9.8N/kg*100m
= 78 400 J
Answer:
<em> Tides are the rise and fall of sea levels. Tides occur due to the gravitational forces exerted on the Earth by moon, and to a lesser extent, the sun. That's why tides occur in ocean or sea.</em>
Hope this helps
