Answer:
joules
Explanation:
Mass–energy equivalence is the principle that says that anything that has mass has an equivalent amount of energy. Converse is also true.
The relation between energy and mass is given by 
Here, E denotes energy, m denotes mass and c denotes speed of light
Mass 
Speed of light (c) = 3 ×
m/s
Therefore,
joules.
The S.I. unit of energy is joules which is equal to

Max ang. speed(u) = 18 rad/s
final ang. speed(v) = 0
ang. displacement(s) = 220 rad
ang. acceleration = (v^2 - u^2)/2s = -18^2 / 2*220 = -0.7364 rad/s^2
v = u +at
0 = 18 - 0.7364t
t = 18/0.7364
t = 24.44 seconds
The best question that could prompt a scientific investigation is: <u>What substances dissolve in ocean water?</u>
This way the person experimenting can use several variables and make observations. Upon making observations, the person can be able to gather as much data as he can in order to answer the original question that he asked.
Answer:
ocean covers 71 percent of the earth
