object's weight is the independent of mass and gravity .
Weight = mass × gravity
I think it's A. Pressure and heat built up in the magma chamber.
An object with greater charge will exert a greater force on an object than an object with smaller charge would. However, if you consider two charges that exert a force on each other, regardless of the magnitude of charge, both charges will exert an equal force on each other because of Newton's third law.
Answer:
The pressure is 
Explanation:
From the question we are told that
