Correct option is: (C) 340 m/s
Correct Answer - A : a B : c C : e D : b E : d
Given: T1 = 27 °C = 27 + 273 = 300 K, v1 = 340 m/s, T2 = 127 °C = 127 + 273 = 400 K To find: Velocity (v2) Formula: \(\frac{v_1}{v_2}=\sqrt{\frac{T_1}{T_2}}\) Calculation: From formula, v2 = v1 \(\sqrt{\frac{T_2}{T_1}}\) = 340, \(\sqrt{\frac{400}{300}}\) =...
Correct option is: (C) 1 : 1
Correct option is: (D) \(\frac{330}{\sqrt{2}}\) m/s
(B) remains unchanged
Correct option is: (B) 440 m/’s
Correct option is: (D) 2040 m
Correct option is: (C) 312 m/s
Correct option is A) pitch
Correct Answer - `20 ms^(-1)`
