You set your stationary bike on a high 80-n friction-like resistive force and cycle for 30 min at a speed of 8.0 m/s . your body is 10% efficient at converting chemical energy in your body into mechanical work.
a.) what is your internal chemical energy change?
b.) how long must you bike to convert 3.8×105 j of chemical potential while staying at this speed? (this amount of energy equals the energy released by the body after eating three slices of bread.)

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
