Answer:
c is correct option thanks to brainly
Power = Work / time
The work given here is 83J and the time it took to do 83J of work was 3s
So..
Power = 83J / 3s
Power = 27.67 W or 27.7 W
Answer:
15.32°
Explanation:
We have given the wavelength
Diffraction grating is 1460 lines per cm
So (as 1 m=100 cm )
For maximum diffraction
here m is order of diffraction
So
Angle α between the velocity of theelectron and the magnetic field of the wire will be 90 degree
Once all hydrogen is depleted the star begins to die
