In what way does a temporary magnet provide an advantage over a permanent magnet?

A 100-N force has a horizontal component of 80 N and a vertical component of 60 N. The force is applied to a cart on a level frictionless floor. The cart starts from rest and moves 2.0 m horizontally along the floor due to this force.

The gravitational force F exerted by the earth on an object having a mass of 100 kg is given by the equation F = 4,000,000 d2 where d is the distance (in km) of the object from the center of the earth, and the force F is measured in newtons (N).

A block has a mass of 20g and measures 2cmx4cmx2cm will it sink or float

The gravitational force between two objects with masses, m1 and m2, separated by a distance "r" is given by F = (Gm1m2) / r2, where G is a constant. When the mass of m2 increases, the force between the two objects:
