Answer:

Step-by-step explanation:
The equation for photon energy is given by:

Where:

This equation telling us that the higher the frequency of the photon, the greater its energy. And the longer the photon wavelength, the lower its energy.
So, replacing the data provided in the previous equation:

Answer:
70910 (c)
Step-by-step explanation:
You move the decimal point to the right each time.
Answer:
you would - 1 to -7 and get -8 then divide -8 by -2 than it would be 4
Step-by-step explanation:
You have to get y by its self but don’t add 4x to 104 put it as 2y=104+4x then divide them all by 2
I think the answer would be 57.75
