What are two factor that effect the force of gravitation

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

The discovery of the electron as a subatomic particle was a result of
