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:
The average acceleration is
Explanation:
<u>Uniform Acceleration </u>
When an object varies its velocity at the same rate, the acceleration is constant.
The relation between the initial and final speeds is:
Where:
vf = Final speed
vo = Initial speed
a = Constant acceleration
t = Elapsed time
The acceleration can be calculated by solving for a:
The Indy 500 race car increases its speed from vo=4 m/s to vf=36 m/s in t=4 s. Thus, the average acceleration is:
The average acceleration is
