Answer:
The magnetic compass shows no deflection.
Explanation:
- When a magnetic compass is placed on a current-carrying conductor, the compass needle shows deflection.
- When the direction of the current is reversed, the needle deflects in the opposite direction.
- This is due to the fact that the current-carrying conductor generates a magnetic field around it.
- If the direction of the current is reversed, the magnetic polarization changes.
- This phenomenon was first noticed by Oersted, and later it helped to develop electromagnetism.
Explanation:
Given
height of building (h)=54 m
Projectile velocity=330 m/s
initial vertical velocity
Initial horizontal velocity
Time taken to cover vertical height of 54 m
t=3.31 s
Horizontal distance traveled in this time
Vertical component of velocity when it hits the ground
v=u+at
