9. An ore cart of mass 1200 kg is rolling at a speed of 10.8 m/s across a flat surface. A crane dumps 496 kg of ore into the cart from directly above it. How fast does the cart move after being loaded with ore? Assume that frictional forces with the flat surface are negligible.
O 6.9 m/s
O 7.6 m/s
O 4.6 m/s
5.1 m/s

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).
