The force of friction that is acting on the suitcase is the force that opposes the motion of the suitcase.
<h3>What is friction?</h3>
The force that resists the motion between two bodies in contact. There are some materials that reduces friction such as oil in a car engine reduces friction. In this example, friction creates between the motion of suitcase and with the ground.
So we can conclude that the force of friction that is acting on the suitcase is the force that opposes the motion of the suitcase.

Answer:
Explanation:
q1 = 3q at (0,0)
q2 = - 2q at (5, 0)
Let the potential is zero at a distance x from the origin


15 - 3x = 2x
5x = 15
x = 3 m
Thus, the potential is zero at x = 3 m .
Option (d) is true.
Impulse is defined as change in momentum of object
so here we can say
Impulse = final momentum - initial momentum


here we know that
m = 0.145 kg


now we will have


so impulse of the bat on ball is approx 13.1 kg m/s
Answer:
A. the amount of steam added to the air s 0.065kgH20/kg dry air
B.the amount of heat transfer to the air in the heating section is 5.1KJ/Kg of dry air
