A 72 kg athlete climbs a rope to a height of 12m. Calculate the increase in gravitational potential energy it has experienced.
Answer:
8467.2J
Explanation:
Given parameters:
Mass of the athlete = 72kg
Height of the climb = 12m
Unknown:
Increase in gravitational potential energy it has experienced = ?
Solution:
Gravitational potential energy is the energy due to the position of a body. It is mathematically expressed as;
Gravitational potential energy = m x g x h
m is the mass
g is the acceleration due to gravity = 9.8m/s²
h is the height
Insert the parameters and solve;
Gravitational potential energy = 72 x 9.8 x 12
GPE = 8467.2J
The black fur absorbs all the colors where the white fun reflects all the colors because we see the green grass it absorbs all the colors except green and the yellow dandelion is reflecting yellow and orange because it’s color is like a mix of them but it still absorbs the other colors
Well because the lowest possibility of having a decen is 3-decene so 6-decene is not possible. Hope this helps!! :)
The correct answer is:
