Answer:
The potential energy of the ball having 2kg mass would be
J
Step-by-step explanation:
I am assuming the ball has a mass of 2 kg, as you have not mentioned the mass of a ball.
Considering the formula for calculating the gravitational potential energy

As
kg
Acceleration of gravity = g = 9.8 
As the ball is on the height = h = 20 meters
So,

J
Therefore, the potential energy of the ball =
J

Answer:
False. Whole numbers are actually Rational Numbers.
I hope that helps u!!!
So hmm notice the picture below
that's (0, -3)
now, keep in mind, adjacent is 0, opposite is -3, and hypotenuse, or radius, is 3
and recall
