We know the equation for calculation of speed of sound at temperature:
<span>v = 331 m/s + (0.6 m/s/C) * T
</span>Here, T = 30 C
v = 331 m/s + (0.6 m/s/C) * 30 C
v = 331 m/s + 18 m/s
v = 349 m/s
In short, Your Answer would be 349 m/s
Hope this helps!
Answer:
Given, length of wire, l = 2m
cross sectional area , A = 10^-4 m²
Load , F = 102kgwt = 102 × 9.8 N
extension of wire, ∆l = 0.1cm = 0.001m
Longitudinal stress = F/A
= 102 × 9.8/(10^-4)
= 999.6 × 10^4 ≈ 1 × 10^7 N/m²
Longitudinal strain. = extension of wire/original length of wire = ∆l/l
= 10^-3/2 = 5 × 10^-4
we know, Young's modulus = longitudinal stress/longitudinal strain
= 1 × 10^7/5 × 10^-4
= 20 × 10^9 N/m²

Answer: If you let a helium balloon go, and if, as it rises, it stays at a constant temperature, the volume of the balloon will. The magnitude of the buoyant force is equal to the weight of the amount of fluid that has the same total volume as the object.
Answer:
huh english plssss bc I didn't understand
Answer:
three halves of a wavelength
Explanation:because a
path difference between waves at minimum is (2n+1)*wavelength /2 therefore at second minimum it is for n=1=1.5 times a wavelength. or three halves a wavelength
