Answer:
Explanation:
It is given that Hair dryer , Toaster and coffeepot are working simultaneously with power 1200 W , 700 W and 800 W respectively.
So the total power of system is
it is given that they work properly until toast is on.
By switching on the toast, appliance stop working because it may cause the circuit to break to safeguard the circuit.
Circuit breaker frame are used in home to prevent the short circuit
The energy of a photon is given by
where h is the Planck constant and f is the photon frequency.
We can find the photon's frequency by using the following relationship:
where c is the speed of light and
is the photon's wavelength. By plugging numbers into the equation, we find
And so now we can find the photon energy
We know that 1 Joule corresponds to
So we can convert the photon's energy into electronvolts:
where h is the Planck constant and f is the photon frequency.
