Answer:
Explanation:
given,
diameter of string A = 0.5 mm
tension in string A = 440 N
diameter of string B = 1 mm
tension in string B = 820 N
wave speed =
M is the linear density that is mass per unit length =mass / length
mass = density x volume
from the above equation
now,
ratio of the wave speed Va/Vb is 1.47

Answer:
Explanation:
5 C = 278 K
25 C = 298 K
V1 / T1 = V2 / T2
1.5L / 278 K = V2 / 298 K
V2 = (1.5L * 298) / 278
V2 = 1.61 L
