(b) Torque will be
Explanation:
We have given dimension of the rectangular 5.4 cm × 8.5 cm
So area of the rectangular coil
Current is given as
Number of turns N = 25
(A) We know that magnetic moment is given by
(b) Magnetic field is given as B = 0.350 T
We know that torque is given by
Answer:
10.791 m/s
5.93505 m
Explanation:
m = Mass of ball
= Final velocity
= Initial velocity
= Final time
= Initial time
g = Acceleration due to gravity = 9.81 m/s²
From the momentum principle we have
Force
So,
The speed that the ball had just after it left the hand is 10.791 m/s
As the energy of the system is conserved
The maximum height above your hand reached by the ball is 5.93505 m
