The "ears" of a frog are two circular membranes located behind the frog's eyes. in one species of frog each membrane is 0.500 cm in radius. if a source of sound has a power output of 2.50×10−6w, emits sound equally in all directions, and is located 1.50 m from the frog, how much sound energy arrives at one of the membranes each second?

What is magnetic flux? explain faraday's law of induction.

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).
