Answer:
The speed of sound for middle C is 345.01 m/s.
Explanation:
Given that,
The frequency of middle C is 261.63 Hz
The wavelength of middle C note used when playing or singing music,
We need to find the speed of sound for middle C. We know that the relation between speed, frequency and wavelength is given by the formula as follows :
So, the speed of sound for middle C is 345.01 m/s. Hence, this is the required solution.
Answer:
Net charge inside the cube is 321.6 C
Explanation:
Given charge density function is ρ =
side of cube is 2m
According to the definition of volume charge density total charge is given by
q = total charge = where dv = dxdydz is the volume element
on substututing the respected values we get
q =
on solving the above integration we get
q = x
x
⇒ q = 321.6 C
Therefore net charge inside the cube is 321.6 C
