PLEASE HELP Ms. Shafor and her husband are trying to move a 42kg couch in their house. Her
husband pushes with a 63N force, and she pushes with a 46N in the same
direction. What is the net force on the couch?

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
