Question

Comprehension for Q. 49 to 51: A stretched string has linear density $μ = 525$ g/m and is under tension $T = 45$ N. A sinusoidal wave with frequency $f = 120$ Hz and amplitude 8.5 mm is sent along the string from one end. The rate at which the wave transports energy is:

Options:

Answer:

C

Solution:

$P = \frac{1}{2} μv ω^{2} A^{2} = 0.5 \times 0.525 \times 9.26 \times 75 4^{2} \times 0.0085^{2} \approx 100$ W.

TestHub · Accepted Answer

P = 2 1 ​ μv ω 2 A 2 = 0.5 × 0.525 × 9.26 × 75 4 2 × 0.0085 2 ≈ 100 W.
