Answer:
Gravity on the moon, g = 1.69 m/s²
Explanation:
It is given that,
Length of pendulum, l = 1 m
Time period, T = 4.82 seconds
We have to find the gravity of the moon. The time period of the pendulum is given by :
g = acceleration due to gravity on moon
g = 1.69 m/s²
Hence, the gravity on the moon is 1.69 m/s².
Answer:
B = 0.088 T
Explanation:
Given that,
The length of a solenoid, l = 0.4 m
No. of turns of wire, N = 356
Current, I = 79 A
We need to find the magnitude of the magnetic field at the center of the solenoid. It is given by the formula.
So, the magnitude of the magnetic field at the center of the solenoid is 0.088 T.
