Answer:
F = 352 N
Explanation:
we know that:
F*t = ΔP
so:
F*t = M-M
where F is the force excerted by the wall, t is the time, M the mass of the ball, the final velocity of the ball and
the initial velocity.
Replacing values, we get:
F(0.05s) = (0.8 kg)(11m/s)-(0.8 kg)(-11m/s)
solving for F:
F = 352 N
Answer:
Attractive
Explanation:
Data provided in the question
The potential energy of a pair of hydrogen atoms given by
Based on the given information, the force that one atom exerts on the other is
Potential energy μ =
Force exerted by one atom upon another
or
or
As we can see that the comes in positive and constant which represents that the force is negative that means the force is attractive in nature
Answer:
Explanation:
Given that,
The magnitude of magnetic field, B = 2.21
We need to find the magnitude of the electric field. Let it is E. So,
Put all the values,
So, the magnitude of the electric field is equal to .
