Answer:
The free electrons tend to Negatively Charged body to Positively Charged body
Explanation:
As they have different charges, Electrons are more attracted to the Positive or it's opposite charge.
Answer:
I = 1.525 kg.m/s
Explanation:
given,
mass of the ball = 0.165 Kg
height of drop, h = 1.25 m
ball rebound and reach to height, h' = 0.940 m
impulse = ?
using conservation of energy
Potential energy is converted into kinetic energy
v = 4.95 m/s
velocity of the ball after rebound
again using conservation of energy
v' = 4.29 m/s
impulse is equal to change in momentum
I = m ( v' - v )
I = 0.165 x ( 4.29 - (-4.95))
I = 1.525 kg.m/s
Answer:
The horizontal force acting on m2 is F + 9.8m1
Explanation:
Given;
Block m1 on left of block m2
Make a sketch of this problem;
F →→→→→→→→→→→-------m1--------m2
Apply Newton's second law of motion;
F = ma
where;
m is the total mass of the body
a is the acceleration of the body
The horizontal force acting on block m2 is the force applied to block m1 and force due to weight of block m1
F₂ = F + W1
F₂ = F + m1g
F₂ = F + 9.8m1
Therefore, the horizontal force acting on m2 is F + 9.8m1
