Given Information:
Diameter of solenoid = 5.0 cm
Magnetic field = B = 2.0 T
Rate of change of magnetic field = 3.0 T/s
Required Information:
Electric field strength inside the solenoid at a point on the axis = ?
Answer:
The electric field strength inside the solenoid at a point on the axis is zero.
Explanation:
From the Faraday's Law
E = -r/2 dB/dt
Where dB/dt is the rate of change of magnetic field and r is zero because the distance from the axis is zero.
Therefore, electric field strength inside the solenoid at a point on the axis is 0.
Answer:
it is accelerating 14 m/s

Answer:
The speed of the golf ball is much greater than the speed of the bowling ball.
Explanation:
Answer:
Mechanical advantage is the measure of the force amplification achieved by using a tool , mechanical device or machine . The machine preserve the input power and supply trade off force. against movement to obtain a desired amplification in the output force .
