Wind or gravitational pull. A wave is made by friction between wind and the water’s surface. Waves can also be made by the sun and moon’s gravitational pull on the earth.
Answer:
The second answer from the top, no the energy in the wave pushed the water particles from above the earthquake in the opposite direction.
Explanation:
I believe this is the correct answer. Hope you do well
Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that orbital velocity at certain height from the surface of Earth is given as

here we know that



now we have


Part b)
When a loose rivet is moving in same orbit but at 90 degree with the previous orbit path then in that case the relative speed of the rivet with respect to the satellite is given as

-- "Free fall" means no forces acting on the object except for gravity.
-- An object dropped through air has two forces on it -- gravity and air resistance.
-- So we're looking for the part of the drop where air resistance is smallest.
-- The force of air resistance depends on the speed through the air, so the
force of air resistance is smallest when <em>velocity downward is smallest</em>.
P=w/t
so the answer is 500/10=50
