Abody of mass 20 kg is kept in equilibrium of two forces. if one of the ropes pull the body in a horizontal direction and the other in a direction of 60 degree with the vertical, calculate the tension in each rope.

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).
