Answer:
Explanation:
Given that the temperature of 
of water and 
of water are
at 
and 
respectively.
Let 
, 
and 
, 
.
The specific heat capacity of water is,
.
Let the final temperature of the mixture be 
.
As there is no energy loss, so, the energy loss by the water at higher temperature, i.e. , will be equal to the energy gain by the water at lower temperature, i.e. .
[ both sides divided by 
]
Now, putting the given value in the above equation, we have
Hence, the temperature of the mixture will be .
Answer:
Wavelength can always be found by measuring the distance between any two corresponding points on adjacent waves. In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction.
