Suppose a star the size of our sun, but of mass 9.0 times as great, were rotating at a speed of 1.0 revolution every 17 days. if it were to undergo gravitational collapse to a neutron star of radius 15 km, losing 3/4 of its mass in the process, what would its rotation speed be? assume the star is a uniform sphere at all times

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

Occurs when an energy source transfers heat directly to another subject space; an example would be an object becoming warm by sitting in the sunshine

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).
