The electron-volt, eV, is a unit of energy (1eV = 1.602 ·10-19 J, 1 MeV = 1.602 ·10-13 J). Since the unit of momentum is an energy unit divided by a velocity unit, nuclear physicists usually specify momenta of nuclei in units of MeV/c, where c is the speed of light (c = 2.998 ·108 m/s). In the same units, the mass of a proton (1.673 ·10-27 kg) is given as 938.3 MeV/c2. If a proton moves with a speed of 15300 km/s, what is its momentum in units of MeV/c?
A block of wood in the shape of a cube, 5.0 cm on a side, is floating in water with its top face parallel to the surface of the water. With a ruler, What is the density of that piece of wood
A beam of ultraviolet radiation, with frequency of 2.710×1015 Hz is directed on a clean metal surface. Calculate the maximum kinetic energy for an electron dislodged from the surface by the radiation
In Example 8-10, mass m1 = 2.40 kg is connected to mass m2 = 1.80 kg as shown. Suppose the two masses start from rest and are moving with a speed of 1.95 m/s just before m2 hits the floor. (a) If the coefficient of kinetic friction is µk = 0.320, wha..
A person walks into a room that has, on opposite walls, two planemirrors producing multiple images. When the person is 5.00 ft from the mirror on theleft wall and 10.0 ft from the mirror on the right wall, find the distances from the person to the..
