You discover a binary star system in which one member is a15 solar mass main-sequence star and the other star is a 10 solar mass giant star. How do we believe that a star system such as this might have come to exist?
A) The two stars probably were once separate but became a binary when a close encounter allowed their mutual gravity to pull them together. B) Other than the very low odds of finding a system with two such massive stars, there is nothing surprising about the fact that such systems exist. C) The main-sequence star probably is a pulsating variable star and therefore appears to be less massive than it really is. D) Although both stars probably formed from the same clump of gas, the more massive one must have had its birth slowed so that it became a main-sequence star millions of years later than its less massive companion. E) The giant must once have been the more massive star but transferred some of its mass to its companion.
A 3.50 kg block is pulled along a moving conveyor belt at a constant speed of 0.500 m/s relative to a stationary observer while the belt moves at a constant speed of 0.200 m/s in the same direction. If the coefficient of kinetic friction is 0.400, the magnitude of the mechanical energy dissipated, in J, caused by the force of friction on the block in 8.00 s is
