Answer:
its 117 times greater then the moon
Answer:
A. 29.4 Joules
Explanation:
Given parameters:
Mass of the book = 1.5kg
Height of lift = 2m
Unknown:
Potential energy acquired = ?
Solution:
Potential energy is the energy due to the position of a body.
Mathematically;
Potential energy = mgh
m is the mass of the body
g is the acceleration due to gravity = 9.8m/s²
h is the height
Potential energy = 1.5 x 9.8 x 2
Potential energy = 29.4J
Answer would be B. Earthquakes happen most of the time when a volcano is about to erupt.
The continental crust is made up of rocks that consist primarily of silica and alumina called the "sial". The next layer of the Earth is called the mantle.
