Answer: Potential Energy: PE = m x g x h Mass: m = PE / (g x h) Acceleration of Gravity: g = PE / (m x h) Height: h = PE / (m x g) Where, m = Mass, g = Acceleration of Gravity h = Height Gravitational Acceleration of the earth is 9.8 m/sec2.

Answer:
Mass = 18.0 kg
Explanation:
From Hooke's law,
F = ke
where: F is the force, k is the spring constant and e is the extension.
But, F = mg
So that,
mg = ke
On the Earth, let the gravitational force be 10 m/.
3.0 x 10 = k x 5.0
30 = 5k
⇒ k = ................ 1
On the Moon, the gravitational force is of that on the Earth.
m x = k x 5.0
= 5k
⇒ k = ............. 2
Equating 1 and 2, we have;
=
m =
= 18.0
m = 18.0 kg
The mass required to produce the same extension on the Moon is 18 kg.
The polarized glasses contain a special filter that blocks the glares and the hazes while driving through the sun or looking at the water, which makes your eyes more comfortable and makes you see better.
Hope this Helps! :)
The answer is no. The formula for density is <span>p=m/V. Everything about the lemonade stays the same except the container it was in. And because the lemonade itself did not change in any way the density of it stays the same.</span>
