Answer:
a) E = 0
b) 
Explanation:
The electric field for all points outside the spherical shell is given as follows;
a) 
From which we have;

E = 0/A = 0
E = 0
b) 


By Gauss theorem, we have;

Therefore, we get;

The electrical field outside the spherical shell


Therefore, we have;

Movement can be without change in positions. As only a part of it can be made to move. If you move there is a motion and if there is a motion there is a movement so they're same thing. In motion whole of body moves, but in movements only the parts of body moves.
The pressure at 100 meters below the surface of sea water with a density of 1150kg is 145.96 psi.
Because of the rule of mask.
Answer:
The loop of coils - Electromagnetic induction is caused a changing magnetic field moving thru a closed loop(s) of coils
