When hot water is poured on the can in a bucket of cold water, the can crushes off means it gets unshaped
A. because as the merry-go-round spins the child accelerates towards the center of the merry-go-round at a uniform rate.
To solve this problem we will apply the concept related to the magnetic dipole moment that is defined as the product between the current and the object area. In our case we have the radius so we will get the area, which would be



Once the area is obtained, it is possible to calculate the magnetic dipole moment considering the previously given definition:



Therefore the magnetic dipole moment is
