A proton with a speed of 5.0 x 106 m/s passes through a metal film of thickness 0.010mm and emerges with a speed of 2.0 x 106m/s. (a) Determine the kinetic energy lost by the proton as it passed through the film. (b) Find the magnitude of the average force acting on the proton as it passed through the metal film.
Un protón en un acelerador de partículas tiene una rapidez de 5.0 x 106m/s. El protón se encuentra con un campo magnético cuya magnitud es 0.40 T y su dirección es 30 grados con respecto a la rapidez del protón. Halle la magnitud de la fuerza magnética actuando en el protón y encuentre su aceleración.
Consider the following mass distribution where the x- and y-coordinates are given in meters: 5.0 kg at (0.0, 0.0) m, 3.6 kg at (0.0, 3.4) m, and 4.0 kg at (2.6, 0.0) m. Where should a fourth object of 7.4 kg be placed so that the center of gravity of the four-object arrangement will be at (0.0, 0.0) m? x = m y = m
Consider the following mass distribution where the x- and y-coordinates are given in meters: 5.0 kg at (0.0, 0.0) m, 3.3 kg at (0.0, 3.7) m, and 4.0 kg at (3.5, 0.0) m. Where should a fourth object of 7.9 kg be placed so that the center of gravity of the four-object arrangement will be at (0.0, 0.0) m?
