Find the gpe of 40,000 kg airplane moving at 80 m/s at 200 meter above the ground.

The airplane gravitational potential energy is 78.4 MJ.

Explanation:

Given:

Mass of airplane, m = 40000 kg

Height above ground , h = 200 m

To Find:

Gravitational Potential Energy = ?

Solution:

Gravitational Potential Energy :

Gravitational potential energy is energy an object possesses because of its position in a gravitational field.

Formula is given by

Where,

m = mass

g = acceleration due to gravity = 9.8 m/s²

h = height

Substituting the values we get

The airplane gravitational potential energy is 78.4 MJ.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
