Explanation:
A wall that is acted upon by a force of 20N does not move suggests that no work has been done on the wall.
Work done is the force applied to move in the direction of the applied force.
Work done = force x distance.
Since the distance is 0, the work done on the body too is zero.
Work is only done when forces moves a body through a given distance.

Answer:
electrons are transferred from the wool shirt to the plastic rod is 4.375 × electrons
Explanation:
given data
Amount of charge transferred Q = -0.7 μC = -0.7 × C
electrons of charge e = -1.6 × C
solution
we apply formula here for total charge of electrons that is
Q = n × e ...................2
here n is no of electron that is
n =
put here value
n =
n = 4.375 × electrons
so here electrons are transferred from the wool shirt to the plastic rod is 4.375 × electrons
Answer:
2.5 ms⁻²
Explanation:
By Newton's 2nd law,
The rate of change of momentum is directly proportional to the unbalance force applied on the object,
By that you can get the equation,
F = ma ⇒ a = F/m
where terms are in usual meaning
a = 3750/1500 = 2.5 ms⁻²
