If a runner exerts 350 J of work to make 125 W of power, then how long did it take the runner to do the work?

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

Amajor difference radio waves, visible light, and gamma rays is the of the photons, which results in different photon frequencies and wavelengths
