An arsenic surface emits electrons after shining with a light source of the frequency of 5.32×1023 hz. calculate the maximum kinetic energy of the ejected electron if the work function of arsenic is 7.67×10.

The  maximum kinetic energy of the ejected electron=

Explanation:

We are given that

Frequency of light source= Hz

Work function of arsenic= eV

We have to find the maximum kinetic energy of ejected electron.

We know that the maximum kinetic energy of ejected electron

Where h=Plank's constant=

=Frequency of light source

=Work function

Substitute the values in the given formula

Then, the maximum kinetic energy of ejected electron

Because 1 e V=

J

Hence, the maximum kinetic energy of the ejected electron=

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
