the acceleration of a body in free fall depends on the place or the world in which it is, true or false?

A square loop of wire consisting of a single turn is perpendicular to a uniform magnetic field. the square loop is then re-formed into a circular loop, which also consists of a single turn and is also perpendicular to the same magnetic field.

A thin cylindrical shell and a solid cylinder have the same mass and radius. The two are released side by side and roll down, without slipping, from the top of an inclined plane that is 1.8 m above the ground.

The water in a lake is at 5 °C. A diver measures the pressure of the water at two different depths in the lake. He repeats the measurements on a different day when the water is at 15°C.
