Can anyone give the answer of this

Yo sup??

Initial gravitational energy=50*75*10

=37500J

Final gravitational energy=50*60*10

=30000J

Change in gravitational potential energy=7500 J

Hope this helps

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
