the symbol of mass is similar to meter but actually it is different,ve careful
Answer:
Explanation:
First of all, we need to calculate the energy of the x-ray photon emitted during the transition from K-shell to L-shell, and this energy is equal to the difference in energy between the two levels:
Converting into Joules,
Now we know that the energy of the photon is related to its wavelength by:
where
h is the Planck constant
c is the speed of light
is the wavelength
Re-arranging the equation for , we find
Answer:
The induced emf for this silver circle during this period of expansion is 0.0314 V.
Explanation:
Given that,
Initial radius = 0.075 m
Magnetic field = 1.5 T
Radius = 0.125 m
Time t =1.5 s
We need to calculate the induced emf for this silver circle
Using formula of emf
Put the value ino the formula
Hence, The induced emf for this silver circle during this period of expansion is 0.0314 V.
Answer:
When the piston is pulled up, air gets sucked into the pump through the inlet. The pump chamber depressurizes as it fills with air. When the piston is forced down, the air becomes compressed and closes the inlet. Then the air flows out from the outlet
