Answer:
5365 N
Explanation:
v = Final velocity = 23 m/s
u = Initial velocity = -14 m/s (opposite direction)
m = Mass of ball = 145 g
t = Time taken = 1 ms
Impulse is given by
Impulse is also given by
The magnitude of the average force exerted by the bat on the ball is 5365 N
If total charge Q is enclosed in the surface of cube
then we will have say that total flux linked with all surfaces of the cube will be given by
since the position of charge is symmetric with respect to the center of the cube so here this whole flux will be equally linked with each of the face of the cube
So here total 6 faces of the cube is there and the total flux of the charge will equally divide in these 6 faces
so flux linked with each face is given by formula
so each face will have above flux due to central position of charge Q
Answer:
F = 1.2x 10^6 N
Explanation:
The explanation is in the attached file
Density is mass per unit volume,
so to get the volume, divide the mass by the density,
So the volume is
