A 170 lb fire fighter is carrying 75 lb of equipment up (10 in.) stairs. There are 15 stairs per story in this building. How many dietary calories does the fire fighter burn in climbing 10 flights of stairs

Calculate the total force on the Earth due to Venus, Jupiter, and Saturn, assuming all four planets are in a line. The masses are Mv=0.815ME, MJ=318ME, Msat=95.1ME, Msun=1.99x10^30kg, ME=5.

The force required to open air bags is dangerous for:

A potential difference of 3.27 nV is set up across a 2.16 cm length of copper wire that has a radius of 2.33 mm. How much charge drifts through a cross section in 3.23 ms? Assume that the resistivity of copper is 1.69 * 10-8 Ω·m.

Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of - 2.0 µC; sphere B carries a charge of - 6.0 µC; and sphere C carries a charge of + 4.0 µC. Spheres A and B are touched together and then separated.

Newton's third law of motion states that the force pair acting on different objects consist of two forces that

While working on her science fair project Venus connected a battery to a circuit that contained a light bulb. Venus decided to change the light bulb to a higher resistance, but she wanted to keep the current the same.
