a gas is contained in a cylinder fitted with a movable piston. a 12 lb weight is placed on top of the piston. calculate the force exerted on the piston

If forces acting on an object are unbalanced, which factors may result fron an unbalanced force? check all that apply

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).

How does an observation about an object differ from an inference about that object
