A 2.45m long copper wire has 1.35V across its ends.
Find the electric field strength within the wire.
What's the acceleration of an electron in this field?
A typical drift speed for conduction electrons is 1 mm/s. How far would an electron travel before reaching this speed?
A Carnot engine has a power output of 130 kW. The engine operates between two reservoirs at 20°C and 500°C, How much energy does it take in per hour
A 145 g wire is held under a tension of 258 N with one end at x = 0 and the other at x = 13.0 m. At time t = 0, pulse 1 is sent along the wire from the end at x = 13.0 m. At time t = 30.9 ms, pulse 2 is sent along the wire from the end at x = 0. A..
The loaded cab of an elevator has a mass of 3.00 multiplied by 103 kg and moves 171 m up the shaft in 23s at constant speed. At what average speed does the force from the cable do work on the cab?
An electron travelling east with velocity 7.0 x10^5 m/s enters the same electric field region as in the previous problem. How far does it go before being turned backward
A bullet is fired through a board 10.0 cm thick in such a way that the bullet's line of motion is perpendicular to the face of the board. The initial speed of the bullet is 400 m/s and it emerges from the other side of the board with a speed of 30..
What would be the speed of the boxes while box B has fallen a distance of 0.5m? The coefficient of kinetic friction between box A and the surface it slides on is 0.20. Make use of conservation of energy.
A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8..00 m/s at an angle of 20.0 below the horizontal, Find the height from which the ball was thrown
A string 1.50 m long will break if the tension in it exceeds 2X10^2N. How fast (in m/s) can a rock of mass 1.50 kg be whirled in a circular horizontal path if the string is not to break? Assume the rock moves on a smooth horizontal surface (No fri..
Where does package hit the ground relative to the point
Nothing, the charges are too cold to deliver any response. D. There is a localization of negative charge near the door handle.
