The energy of the photon emitted when an electron in a mercury atom drops from energy level f to energy level b is 3.06 eV.
<h3>Change in energy level of the electron</h3>
When photons jump from a higher energy level to a lower level, they emit or radiate energy.
The change in energy level of the electrons is calculated as follows;
ΔE = Eb - Ef
ΔE = -2.68 eV - (-5.74 eV)
ΔE = 3.06 eV
Thus, the energy of the photon emitted when an electron in a mercury atom drops from energy level f to energy level b is 3.06 eV.

Generally given that the electric field is negative it mean that its direction is opposite to that of the force
Momentum is a property of moving objects but not stationary objects. You can see this in the formula because momentum equals mass times velocity squared (p=m*v^2). You would not have momentum if you didn't have velocity. Stationary objects have potential energy, and things with potential energy do not have velocity. This is why momentum is a property of moving objects but not of stationary objects.
Answer:
The energy consumption by toaster oven is 432 kJ and that of fluorescent light (CFL) bulb is 435 kJ.
Explanation:
Power of toaster oven, P = 1.2 kW
Time, t = 6 minutes = 360 s
The energy used by toaster oven is given by :
Power of fluorescent light (CFL) bulb, P' = 11 W
Time, t' = 11 h = 39600 s
Energy used by fluorescent light (CFL) bulb is given by :
So, the energy consumption by toaster oven is 432 kJ and that of fluorescent light (CFL) bulb is 435 kJ.
