Answer:
Explanation:
As we know that electrostatic potential energy of the electron is converting here into kinetic energy
so we will have
so here we know that
so from above equation we have
Answer:
1426.8 N
Explanation:
Pressure, P = 3567 Pa
The area of Mr. Rosa’s foot, A = 0.4 m²
We need to find the force does one kick from Mr. Rosa create. The pressure acting due to force is given by :
where
F is force
So, the required force is 1426.8 N.
Answer:
(a)
(b) v = 1064 m/s
Explanation:
(a) Frequency of electromagnetic wave,
Let is the wavelength of electromagnetic wave. It can be calculated as :
(b) Frequency of medium, f = 532 Hz
Wavelength,
Let v is the speed of sound wave in an unknown fluid. Using the relation as :
v = 1064 m/s
Hence, this is the required solution.
