Answer 1

3). while you are sounding a tone on a toy whistle a friend e notice , you you want running towards you . If her to hear the same that you hear even ' you must frequency though she is approaching (C) run away from her at the same Speed:

0:0050 4) A piano string is under of density kg/m a tension (T) of 1350 N . M = m I - 0.005 kg/m T = 1350 so velocity of the wave, V = 표 = 1350 0.005 M ve 520 mis SO correct option is (b 5) speed of sound in air depends upon C) Temperature of the Air.
