Answer:
option (D
Explanation:
Torque is given by
torque = N x i x A x B x sinФ
where, N is number of turns, A is area, b is the magnetic field and Ф be the angle between the area vector and the magnetic field vector, i be the current.
So, torque depends on the current.
option (D)
<span>you must first select an axis of rotation about which to calculate moment arms and torques. </span>
ALL radioactivity matter has a set, unchanging, rate of decay. so if you measure the radioactive matter in an object, you can figure out how long it has been on the planet, based on what level of decay it is at.
Answer:
NS/NS
Explanation:
If we cut a bar magnet in half pieces according to the image that is given below the question, then the magnet will show NS/NS that is (North-South/North-South) because the smaller pieces of the magnet will become a small magnet with the same property-carrying both the poles, north pole as well as south pole. The poles will not be separated.
