Explanation:
It is given that,
Frequency of vibration, f = 215 Hz
Amplitude, A = 0.832 mm
(a) Let T is the period of this motion. It is given by the following relation as :
(b) Speed of sound in air, v = 343 m/s
It can be given by :
Hence, this is the required solution.
Forced-Air would be the type of central heating system
the puck recoils in each case.
larger mass stone gives puck greater recoil, smaller stone, smaller recoil
It is the last number minus 3
