Answer:
Induced emf of the wire is 6.36 Volts.
Explanation:
It is given that,
Length of the wire, l = 75 cm = 0.75 m
Magnetic field, B = 0.53 T
Velocity, v = 16 m/s
The wire is moving straight up in the magnetic field. So, an emf is induced in the wire. It is given by :
So, the induced emf of the wire is 6.36 V. Hence, the correct option is (b) "6.36 V".
The club was in contact with the ball for 0.013 seconds.
Why?
We can calculate for how long was the club in contact with the ball using the following equation and isolating the time from it:
From the statement we know:
- Initial speed equal to zero.
- Force equal to 272N.
- Final speed (for the moment) equal to 62 m/s.
- Mass equal to 0.058 Kg
So, substituting and calculating, we have:
Hence, we have:
Variables: Time
Equations:
Answers: The club was in contact with the ball for 0.013 seconds.
Have a nice day!
