Newtons law of gravitation is F=GMm/r^2, where F is the force between two objects, M and m are the mases of the two objects, G is the universal gravitational constant, and r is the distance between two objects. By knowing information about the size of the earth and making a few measurements, this formula can allow you to determine the mass of the earth. Solve this equation for M

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
