The direction of the motion is constantly changing during
motion over any closed path, not only circular.
I would say the same thing as the first answer
Answer:
a) Left to right
b) 1.51 A
Explanation:
a)
The gravitational force on the rod due to its mass is in downward direction. hence to levitate the rod, the magnetic force on the rod must be in upward direction.
The magnetic field is inward to page and magnetic force must be upward. Using right hand rule, the current must be flowing from left to right.
Left to right
b)
L = length of the copper rod = 0.570 m
m = mass of the rod = 0.059 kg
B = magnitude of magnetic field in the region = 0.670 T
θ = Angle between the magnetic field and rod = 90
i = current flowing throw the rod = ?
The magnetic force on the rod balances the gravitational force on the rod. hence
Magnetic force = gravitational force
mg = i B L Sinθ
(0.059) (9.8) = i (0.670) (0.570) Sin90
i = 1.51 A
Answer:
when the earth quakes...
Explanation:
or An earthquake is caused by a sudden slip on a fault, When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
