(a) The capacitor potential difference increases with time. (b) The capacitor potential difference decreases with time. (c) The capacitor potential difference stays the same.

(a) The capacitor potential difference increases with time when capacitor is being charged.

Explanation:

A capacitor is a device which is used to store electric energy as charge.

As a capacitor is charged, its potential difference increases gradually with time.

Potential difference in a capacitor depends on shape and size of the electrodes used in capacitor.

Potential difference is created between two plates of a capacitor when it is fully charged.

The charge stored on the plates of the capacitor is directly proportional to the voltage.

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m

the awnser is d you right bro
