vector b is the answer...............
Answer:
Magnetic field, B = 0.0196 T
Explanation:
A current of 0.6 amps flows through a solenoid 6500 turns and 25 cm long. What is the value of the magnetic field inside it?
We have,
Current, I = 0.6 A
Number of turns in the solenoid, N = 6500
Length of solenoid, l = 25 cm = 0.25 m
The magnetic field inside the solenoid is given by :
So, the value of the magnetic field inside the solenoid is 0.0196 T.
Answer:
Because the ball is dropped, we are going to assume its initial velocity is 0. With that said, acceleration is essentially the change in the velocity versus the change in time, hence the unit m/s^2, which can be thought of as “meters per second per second.” The only force acting on the ball is gravity.
That being said, you can simply divide the change in velocity by the change in time, giving you an answer of 9.8 m/s^2, which is the value of g. Even if they did not give you a time, the answer would still always be the value of g (that is if the question pertains to earth), as acceleration due to gravity is a constant.
