120 minutes=2 hours
20/2= 10mph
Explanation:
It is given that,
Distance, r = 3.5 m
Electric field due to an infinite wall of charges, E = 125 N/C
We need to find the electric field 1.5 meters from the wall, r' = 1.5 m. Let it is equal to E'. For an infinite wall of charge the electric field is given by :

It is clear that the electric field is inversely proportional to the distance. So,


E' = 291.67 N/C
So, the magnitude of the electric field 1.5 meters from the wall is 291.67 N/C. Hence, this is the required solution.
Answer:
0.32 V
Explanation:
N = 10, A = 0.23 m^2, B = 0.47 T, t = 0.34 s
The average induced emf is given by
e = - N dФ / dt
Where, dФ be the change in magnetic flux in time dt.
dФ / dt = d / dt (B A) = A dB/dt
So,
e = - 10 x 0.23 x 0.047 / 0.34 = - 0.32 V
The negative sign shows the direction of induced emf.
