D Question 12 6 pts You are standing 10 m away from a single speaker that is emitting sounds waves into space. You move away from the speaker so that the separation between you and the speaker is now 20 m. What can you say about the intensity of the sounds waves from the speaker at this distance? O The intensity has been reduced by a factor of 1/2 The intensity remains the same O The intensity has increased by a factor of 2 The intensity has been reduced by a factor of 1/4 Previous Next Not saved Submit QuizQuestion 14 6 pts Two wave pulses travel on a string. Wave pulse A displaces the string by -3 mm at x = 8 m. Wave pulse B displaces the string by +2 mm at x = 8 m. If both wave pulses reach x = 8 m at the same time, how much is the string displaced? O +5 mm O -1 mm O -5 mm O +1 mm Previous Next Not saved Submit Quizements Attempt du Question 15 6 pts 13 Minut 9 Two resistors are connected to a battery as shown.
