Since work function is the energy needed to dislodge the electron, I'd say that the unit is Joules or eV (electron Volts).
Work done (joules) and time taken (seconds) is the information needed to calculate power in watts (joules/second).
Approx 2940 Joules.
The needed heat is 47,65 Joules.
10 joules per second = 10 watts
2,26 Kj are necessary
There are 1000J in a single flake!! This is also the amount of joules needed to climb an average flight of stairs!!
10 joules per second = 10 watts
It had better be in joules. Watts and volts are not units of energy. yes, but how many as in ? joules/sec
Voltage is electrical pressure and Joules is a power rating so other info is needed
7000
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
