1.A tsunami is a series of ocean waves caused by an underwater earthquake, landslide, or volcanic eruption. More rarely, a tsunami can be generated by a giant meteor impact with the ocean. These waves can reach heights of over 100 ft.
2.About 80% of tsunamis happen within the Pacific Ocean’s “Ring of Fire.”
3.The first wave of a tsunami is usually not the strongest, successive waves get bigger and stronger.
4.Tsunamis can travel at speeds of about 500 miles or 805 kilometers an hour, almost as fast as a jet plane.
5.The states in the U.S. at greatest risk for tsunamis are Hawaii, Alaska, Washington, Oregon, and California.
Hope it help!
Answer:
F = 3.55 x 10²² N
Explanation:
average distance of sun from earth = 1.5 × 10⁸ km
mass of earth = 6 x 10²⁴ kg
time = 365.25 days
distance = 2 π r
distance = 2 π x 1.5 x 10¹¹ m
= 3 π x 10¹¹ m
v = 2.98 x 10⁴ m/s
we know centripetal force
F = 3.55 x 10²² N

Answer:
It takes 77 N
Explanation:
Using Newton's second law of motion, F=ma (Force equals mass times acceleration. Since the mass of the couch is 385 kg and the target acceleration is 0.2 m/s, you simply multiply mass times acceleration (ma) to get the total force, or 77 N.
I think it is 100 dB .I holp it is help.
