For each of the four statements below, indicate whether the bolded statement is true or false, and provide your reasoning by identifying and applying one or more relevant physics concepts. a. If two sound waves interact constructively, the resultant sound wave will be of a higher velocity than either of the two original sound waves. b. The opposite poles of two bar magnets are brought close to but not touching each other. As the two magnets approach, the domains within each magnet will shift in location to concentrate at each pole. c. Two resistors, on with a resistance of 10 Ohms and one with a resistance of 5 Ohms are connected in series. When the circuit is attached to a battery the potential difference across each resistor will be the same. d. The frequency of a sound wave will increase as the wave moves into a less dense medium than the medium it had been moving through.
