<h2>Answers:</h2>
<u>The possible effects on the earth will be</u><u> 1) No light during night 2) No tides</u>
<h2>Explanation:</h2>
As we know that tides are caused by the differential gravitational force on the equatorial regions by the moon. So if the Moon escapes from Earth, the main effect would be the lack of tides on Earth The region closer to the Moon experiences more gravitational force than the region on Earth away from the Moon. Other effects will be no more Moon to light up the night sky and no more solar eclipses.
Answer:
0.2s
Explanation:
SO for the dolphin to hear its echo, the sound wave must travel a distance twice as much as the displacement between the dolphin and the ocean floor. So d = 154 * 2 = 308 m
Since the speed of sound in ocean floor is v = 1533m/s we can find out the time by dividing the distance d by the speed of sound
t = d / v = 308 / 1533 = 0.2s
