Most workers in nanotechnology are actively monitored for excess static charge buildup. the human body acts like an insulator as one walks across a carpet, collecting −50 nc per step. what charge buildup will a worker in a manufacturing plant accumulate if she walks 3535 steps? how many electrons are present in that amount of charge?

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s

Which type of wave can travel without a medium
