<h2>
Cost savings in using the fluorescent bulb is 3.81 cents</h2>
Explanation:
A 100 watt incandescent light bulb is operated for 7 hours.
Energy used by 100 watt incandescent light bulb = Power x Time
Energy used by 100 watt incandescent light bulb = 100 x 7 = 700 Wh
Energy used by 100 watt incandescent light bulb = 0.7 kWh
A 32 watt fluorescent light bulb is operated for 7 hours.
Energy used by 32 watt fluorescent light bulb = Power x Time
Energy used by 32 watt fluorescent light bulb = 32 x 7 = 224 Wh
Energy used by 32 watt fluorescent light bulb = 0.224 kWh
Cost of electricity per kWh = 8 cents
Cost of electricity by 100 watt incandescent light bulb = 0.7 x 8 = 5.6 cents
Cost of electricity by 32 watt fluorescent light bulb = 0.224 x 8 = 1.792 cents
Difference in costs = 5.6 - 1.792 = 3.808 cents
Cost savings in using the fluorescent bulb is 3.81 cents
Carbon-13 has an atomic mass of 13.
Atomic mass is the sum of protons and neutrons.
There are 6 protons, so there are 13 - 6 = 7 neutrons.
Answer is 7 neutrons (and 6 electrons)
D.transverse waves move perpendicular and longitudinal waves move parallel to the direction of energy movement..
The change in pitch of a train's horn as it passes while you are
standing still can be described by the Doppler effect, but that
doesn't explain it.
I think its Coulomb's law<span>
