Answer:
I believe <u>kinetic / potential</u>
Explanation:
Answer:
7m/s^2
Explanation:
using v=u+at
since the car started from rest, u=0 , v=14m/s t=2s
a =acceleration.
14=0+a×2
14=0+2a
14=2a
a= 14/2 =7
a=7m/s^2
Answer:
The mutual inductance is 
Explanation:
From the question we are told that
The number of turns per unit length is 
The radius is 
The number of turns of the solenoid is 
Generally the mutual inductance of the system is mathematically represented as

Where A is the cross-sectional area of the system which is mathematically represented as

substituting values


also
is the permeability of free space with the value 
So
