man i tried for you sorry if i wasnt much help
Answer:
b. AG, work function=4.74eV
Explanation:
Ultraviolet light starts at the end of the visible light spectrum, where violet light ends:
(wavelength of lowest-energy ultraviolet light)
So, the lowest energy of ultraviolet light can be found by using the formula

where
h is the Planck constant
c is the speed of light
Substituting,

And keeping in mind that

This energy converted into electronvolts is

The work function of a metal is the minimum energy needed to extract a photoelectron from the surface of the metal. Therefore, the metals that exhibit photoelectric effect are the ones whose work function is larger than the energy we found previously, so:
b. AG, work function=4.74eV
Because for all the other metals, visible light will be enough to extract photoelectrons.
It’s designed to protect an electrical circuit from damage caused by overcurrent, usually resulting from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.
That’s really just the basic purpose.

Answer:
Explanation:
The linear charge density id defined as the charge per unit length.
Let q be the charge and L be the length of the wire.
So, the linear charge density is
λ = q / L
If the length is 12 times, then charge should also be 12 times to keep the linear charge density same.
Vitamin A may reduce the risk for certain types of cancers. It also increases the activity of immune system cells.
