Unformatted text preview: example of a fusion reaction is 2 1 H + 3 1 H → 4 2 He + neutrons, (a) how many neutrons must be emitted? (Give your reasoning.) (b) If m ( 1 n) = 1 . 009u, and the atomic masses are m ( 2 1 H) = 2 . 014102u, m ( 3 1 H) = 3 . 016049u, and m ( 4 2 He) = 4 . 002603u, how much energy, in Mev units, is released in each fusion? [4] If the gravitational pull by the two masses on each other were given by the magnitude Km 1 m 2 /r 3 instead of the usual expression ( K is a constant), what would the speed be for a satellite in orbit at a distance r from the center of the Earth, whose mass is M ? F m m 1 2 [5] A block of mass m 1 on a smooth, horizontal surface is connected to a second mass m 2 by a light cord over a light, frictionless pulley as shown. (Neglect the masses of the cord and of the pulley.) A force of magnitude F is applied to mass m 1 as shown. Neglect any friction. Find the accelerations of the masses and the tension in the cord....
