Avery long, rectangular loop of wire can slide without friction on a horizontal surface. initially the loop has part of its area in a region of uniform magnetic field that has magnitude b = 2.9 t and is perpendicular to the plane of the loop. the loop has dimension 4.0 cm by 60 cm, mass 24 g, and resistance r = 5.0 × 10^−3 ω. the loop is initially at rest; then a constance force fext = 0.18 n is apllied to the loop to pull it out of the field. (a) what is the acceleration of the loop when v = 3.00 cm/s? (b) what is the loop’s terminal speed when the acceleration becomes zero?

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).
