Answer:
Its gravity potential energy is 39,240 J
Explanation:
The gravity potential energy of a body on the earth's surface is the energy a body under the influence of gravity possesses by virtue of its elevation from the surface of the earth.
We can calculate the GPE using this formula
from the problem given, we have m= mass= 20 kg
g = gravitational constant = 9.81m/s2
height = 200m
Hence, Its gravity potential energy is 39,240 J

Answer:
The warm seas create a large humid air mass. The warm air rises and forms a low pressure cell, known as a tropical depression.
Explanation:
Hurricanes arise in the tropical latitudes (between 10 degrees and 25 degrees N) in summer and autumn when sea surface temperature are 28 degrees C (82 degrees F) or higher.
