A flat coil is in a uniform magnetic field. The magnetic flux through the coil is greatest when the plane of its area is

How much energy is contained in the mass of a 60-kilogram person?

Under constant acceleration the average velocity of a particle is half the sum of its initial and final velocities. Is this still true if the acceleration is not constant? Explain.

Felix has three metal bowls that are the same shape and size. Felix fills each bowl to the top with boiling water. The first bowl holds 2.5 liters, the second bowl holds 1.0 liter, and the third bowl holds 0.75 liters.
