How much mass must an object have to gravitationally infuence another body?

Food has chemical potential energy, which is the energy stored in the bonds between two atoms. This energy is released when what occurs?

Given a wave of a particular wavelength and amplitude, what must be the amplitude, wavelength, and phase change of a wave you add to this wave to create a wave of twice the amplitude?

Explain why you cannot charge one end of a steel rod and leave the other end uncharged

Fish are hung on a spring scale to determine their mass (most fishermen feel no obligation to truthfully report the mass). (a) What is the force constant of the spring in such a scale if it the spring stretches 8.00 cm for a 10.0 kg load

Why is it a good idea to discuss gravity and fluid flows when learning about electricity?

Your body is presently converting chemical potential energy from food into thermal energy at a rate of about 100 J/s, or 100 W. If heat were flowing out of you at a rate of about 200 W, would your body temperature go up or down?
