Answer 1

Answer:

(c) less than Q

Explanation:

Amplitude of P = 0.5cm

Amplitude of Q = 0.8cm

Amp. of P < Amp. of Q

so, loudness of musical note P will also be less than that of Q.

As loudness is directly proportional to the amplitude. Larger the amplitude, louder will be the sound and vise versa.
