Answer:
As the ball gains height it's potential energy will increase and it's kinetic energy will decrease. As the ball falls back down to the ground the kinetic energy will increase and it's potential energy will decrease.
Answer:
<em>2</em><em>, The spring would compress twice the length of </em><em>. </em>
Explanation:
The Spring force is an application of Hooke's law, and using the law of conservation of energy in a spring system, we can find the relationship between the compression length and velocity.
<h3>Step by Step Calculations</h3>
For a spring system, the conservation of energy can be applied using the formula below;
........................................1
Where k is the spring constant
is the distance
m is the mass and
v is the velocity
We have to make the distance the subject formula to know how it affects the velocity;
.....................................2
from the equation, it shows that the distance () is directly proportional to the velocity (v). This implies that when the distance increases the velocity also increases.
x ∝ v
Therefore when the initial speed is doubled to 2 v it will amount a double increase in the distance which is 2
Answer:
A. Gravitational force
C. Their charges
Explanation:
As we'll discuss in this lesson, he found that the force between charged particles was dependent on only two factors: the distance between the particles and the amount of electric charge that they carried.
Hope it help you
have a good day :)
I believe it is the 2nd one because the ground purifies it over a period of a little while.
