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 -50nC per step. What charge build up will a worker in a manufacturing plant accumulate if shewalks 23 steps? How many electrons are present in that emount of charge? And finally if a delicate manufacturing process can be damaged by an electrical discharge of 10^12 electrons, what is the max number of steps any worker should be allowed before touchingthe components?
A loudspeaker of mass 22 is suspended a distance of = 1.6 below the ceiling by two cables that make equal angles with the ceiling. Each cable has the length of = 3.10.
Two identical positive charges exert a repulsive force of 6.2 multiplied by 10-9 N when separated by a distance of 3.4 multiplied by 10-10 m. Calculate the charge of each.
An object moving with uniform acceleration has a velocity of 14.0 cm/s in the positive x-direction when its x-coordinate is 3.18 cm. If its x-coordinate 2.95 s later is ?5.00 cm, what is its acceleration?
If the density and atomic mass of copper are respectively 8.80 103 kg/m3 and 63.5 kg/kmol, Determine the drift speed of the electrons in a 10 gauge copper wire (2.588 mm in diameter) carrying a 19.5 A current
A uniform horizontal wire with a linear mass density of 0.50 g/m carries a 1.8 A current. It is placed in a constant magnetic field with a strength of 4.00 x10-3 T. The field is horizontal and perpendicular to the wire. Neglect the magnetic field ..

What was the spring constant of the Super Bungee? How much time after the Super Bungee was attached did it take the bus to stop.
At t = 0, an automobile travelling north begins to make a turn. It follows one-quarter of the arc of a circle of radius 10.70 m until, at t = 1.60s, it is travelling east. The car does not alter its speed all through the turn.
