Answer:
The wavelength of the interfering waves is 3.14 meters.
Explanation:
Given that,
The equation of standing wave that is formed by interfering two harmonic waves (travelling opposite direction) is given by :
........(1)
The general equation of standing wave is given by :
..............(2)
On comparing equation (1) and (2), we get :
k = 2
We know that,



So, the wavelength of the interfering wave is 3.14 meters. Hence, this is the required solution.

m = mass of water in bathtub = 62.7 kg
= initial temperature of water in tub = 31 c
M = mass of water added = ?
= initial temperature of water added = 76 c
T = final equilibrium temperature of the system = 40.3 c
c = specific heat of water = 4186
Using conservation of heat
Heat gained by water in tub = Heat lost by water added
m c (T -
) = M c (
- T)
m (T -
) = M (
- T)
(62.7) (40.3 - 31) = M (76 - 40.3)
M = 16.3 kg
