Suppose he work function for a metal used in the cathode of a photoelectric cell is 2.40x10-19 Joules. Calculate the value of the longest wavelength for light that has just sufficient energy to cause the emission of photoelectrons from the surface of this metal. What is the color of this light?

This is what i found on google “when one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and atp is converted to adenosine diphosphate (adp). likewise, energy is also released when a phosphate is removed from adp to form adenosine monophosphate (amp).” i hope this you .

The answer should be c.
