Answer:
Look at this picture this is the answer
Explanation:
Answer: 
Explanation:
Given
Initial angular speed is 
Final angular speed is 
Time period 
Magnitude of the fan's acceleration is given by
Insert the values
Thus, fan angular acceleration is
Displacement can be zero so velocity is zero but the distance won’t be zero so speed won’t be zero
Answer:
Given:
Time taken: 3.5 hrs
Speed: 120mi/HR
Now we know that
distance = speed x time
Substituting the given values in the above formula we get
Distance= 120mi/hr x 3 hrs
Distance = 360 mi= 579.36 Km
Explanation:
Answer:
The correct option is;
(b) The end A of the solenoid behaves like a north pole
Explanation:
According to Lenz's law we have that the induced emf direction in the solenoid due to the rapid introduction of the bar magnet will be such that the electric current induced will have a resultant magnet field that will oppose to the movement of the north pole of the bar magnet that resulted in the magnetic field
Therefore, the opposing magnetic pole to the north pole of a magnet is a north pole and the solenoid end A will act like the north pole.
