two small beads having positive charges 3q and q are fixed at the opposite ends of a horizontal, insulating rod, extending from the origin to the point x=d. a third small chatged bead is free to slide on the rod. at what position is the third bead..
so hydrogen atoms have a thermal velocity of about 1000 m/s. How does the energy stored in the magnetic field compare with the kinetic energy in a given volume of space.
A hot dog cooker heats hot dogs by connecting them to 120 V household electricity. A typical hot dog has a mass of 50g and a resistance of 130ohm . How long will it take for the cooker to raise the temperature of the hot dog from 20c to 80c ? The ..
Use graphical techniques to find out the direction of the dog’s resultant displacement vector. Give the direction of the resultant displacement in degrees (out of 360).
