One mole of a substance contains 6.02 × 1023 protons and an equal number of electrons. If the protons could somehow be separated from the electrons and placed in very small, individual containers separated by a million meters, what would be the magnitude of the electrostatic force exerted by one box on the other? Please provide formula.
A flight attendant pulls her 72-N flight bag a distance of 265-m along a level airport floor at a constant velocity. The force she exerts is 44-N at an angle of 57° above the horizontal.
Assume A and B function independently. For the system to function, both components must function. If the probability that A fails is 0.05, and the prob- ability that B fails is 0.03, find the probability that the system functions.
