Q. A 12.0 g conducting rod oflength 1.30 m is free to slide downward between two vertical railswithout friction. The rails are connected to an 8.00 resistor, and the entire apparatus is placed ina 0.560 T uniform magneticfield. Ignore the resistance of the rod and rails.
what is the terminal velocity of the rod?
Q. A parallel-plate capacitor has an area of 5.15 cm2, and the plates are separated by 1.05 mm with air between them. It stores a charge of 337 pC. What is the potential difference across the plates of the capacitor?
A ferry boat transports tourists among three islands. It sails from the first island to the second island, 4.7 km away, in a direction 37.0° north of east. It then sails from the second island to the third island in a direction 69.0° west of north..
An Automobile engine slows down from 4500 rpm to 1200 rpm in 2.50 s. Calculate (a) its angular acceleration, assumed constant and (b) total number of revolutions the engine makes in this time.
A car is slides down an icy driveway that slopes at an angle of 20 degrees. What is an acceleration of the car? Assume that the friction between tires and the icy pavement is negligible.
Two heavy pendula of mass m are suspended from strings of length l inside a railroad car of mass M that can roll freely on horizontal tracks (ignore the moment of inertia of the wheels).
A 2.5 mol sample of helium gas initially at 300 K and 0.400 atm is compressed isothermally to 1.30 atm. Note down that the helium behaves as an ideal gas.
