Imagine that the charge on the proton is bigger in magnitude than the charge on the electron by 1 part in a trillion (10^12). What is the
magnitude of the electrostatic force between you and a friend who is 1 m
away? How much total work did the two of you have to do to get that close
to one another (assuming you started very far apart)?

The sun generates both mechanical and electromagnetic waves. which statement about those wave is true?

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
