Answer:
greater from magnet B to A
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!
<span>Very wild guess at this one, since I've no idea what "standard wave format" means. First gap would be TRANSVERSE. Second gap could be LONGITUDINAL, or SOUND. Third gap could be ELECTROMAGNETIC (the two possible waves being the ELECTRIC wave and the MAGNETIC wave). http://perendis.webs.com</span>
Hello. This question is incomplete. The full question is:
Two blocks are stacked on top of each other on the floor of an elevator. For each of the following situations, select the correct relationship between the magnitudes of the two forces given.
The elevator is moving downward at a constant speed.
The magnitude of the force of the bottom block on the top block is _____ the magnitude of the force of the earth on the top block.
Answer:
The magnitude of the force of the bottom block on top block is equal to the magnitude of the force of the top block on bottom block.
Explanation:
As the elevator is descending, there is only a normal force being applied to the lower surface of the block. This force has a magnitude equal to the force of the upper block, because the only acceleration that is acting in this case is the force of gravity. From that force, the resulting force is zero.
