7. A solenoid with ends marked A and B is suspended by a thread so that the core can rotate in the horizontal
plane. A current is maintained in the coil so that the
electrons move clockwise when viewed from end A
toward end B. How will the coil align itself in Earth's
magnetic field?

What makes thermal imaging cameras useful? they can detect differences in color. they can detect differences in wave speeds. they can detect differences in temperature. they can detect mechanical waves.

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).
