Aproton is accelerated down a uniform electric field of 450 n/c. calculate the acceleration of this proton.

The acceleration of proton will be

Explanation:

We have given electric field E = 450 N/C

Charge on proton

Force on electron due to electric field is given by

Mass of electron

Now according to second law of motion

So

So the acceleration of proton will be

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

the total distance traveled by the car is

30km + 49km = 79 km .
