During a lab experiment on friction, students pull a crate of weights with mass 120 kg along the floor. If they pull with a force of 190 N, and the force of friction between the crate and the ground is measured to be 160 N, what is the net force acting on the crate? What acceleration will the crate experience?

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).
