Q. A photoelectric-effect experiment determines a stopping potential of 1.93 eV while light of 200 nm is used to illuminate the cathode.
1) From what metal is the cathode made?
2) What is the stopping potential if the intensity of the light is doubled?
A 1.00 kg beaker containing 2.0 kg of oil (density=916-kg/m3) rests on a platform scale. A 2.00 kg block of iron is suspended from a spring scale and is completely submerged in the oil.
Calculate the amount of work (in electron-volts) it would take to move an electron from 11.6 to 13.4 away from a +3.50 point charge.
A woman walks 300m in the direction 30° east of north, then 300 m directly east.
Old naval ships fired 13 kg cannon balls from a 210 kg cannon. It was very important to stop the recoil of the cannon, since otherwise the heavy cannon would go careening across the deck of the ship.
What is the intensity of the sound waves at point.
A charge of -3.55 nC and a charge of -5.65 nC are unconnected by a distance of 60.0 cm. Find the position at which a third charge of +7.20 nC can be located so that the net electrostatic force on it is zero.
A rotational axis is directed perpendicular to the plane of a square and is located . Two forces, 1 and 2, are applied to diagonally opposite corners, and act togther the sides of the square, first as shown in part a and then as shown in part b of..
What is the required average power.
calculate the speed of the block at the instant the dielectric leaves the capacitor assuming it starts at rest and that the voltage across the capacitor after the dielectric is removed is measured to be 900 V.
A 40kg child on a 2.30 m long swing is released from rest when the swing supports make an angle of 26 degrees with the vertical. The acceleration of gravity is 9.8 m/s2.
A metal block of mass m slides on a horizontal surface that has been lubricated with a heavy oil so that the block suffers a viscous resistance that varies as the 3/2 power of the speed F(v)=-cv^3/2. If the initial speed of the block is v0 at x=0,..
Four identical charges, +Q, occupy the corners of a square with sides of length a. A fifth charge, q, can be placed at any desired location. Find the loction of the fifth charge, and value of q, such that the net electric force acting on each of t..
