Answer:
Resistance is a measure of the opposition to current flow in an electrical circuit.
Explanation:
Answer:
Explanation:
The formula for hydrogen atomic spectrum is as follows
energy of photon due to transition from higher orbit n₂ to n₁

For layman series n₁ = 1 and n₂ = 2 , 3 , 4 , ... etc
energy of first line

10.2 eV
wavelength of photon = 12375 / 10.2 = 1213.2 A
energy of 2 nd line

= 12.08 eV
wavelength of photon = 12375 / 12.08 = 1024.4 A
energy of third line

12.75 e V
wavelength of photon = 12375 / 12.75 = 970.6 A
energy of fourth line

= 13.056 eV
wavelength of photon = 12375 / 13.05 = 948.3 A
energy of fifth line

13.22 eV
wavelength of photon = 12375 / 13.22 = 936.1 A
Work done is given by product of force and displacement due to that force
So here we will have

here we know that


Now work done is given as


so it will do 16 J work to move the box
