Answer:
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. ... In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A.
Answer:
B) generator
Explanation:
Alternating current is a type of current that changes direction periodically which is produced by a generator. This generator consists of a magnet and a loop of wire which rotates in the magnetic field of the magnet.
Therefore, from the given question, alternating current is normally produced by a generator.
Option B is the correct answer
Answer:
F = 132N
Explanation:
Let the pulling force be F
Given the mass of the barrel is 12 Kg and The acceleration is 1.2 m/
We know that Net Force =
Now net force = F - mg
F - mg = ma
F = mg + ma
F = m(a+g) =
Note that there will be a downward force acting on the body which is equal to mg
The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges.
