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:
273 Kelvin
Explanation:
If -273 Celsius is 0 Kelvin, then 273 Kelvin will be 0 Celsius.
