Much power does a 10 Ohm bulb have in a series circuit with a battery of 12V and nothing else in the the circuit? a- 35.8W
b- 82.3W
c- 120W
d- 14.4W

Hel please I’m in the exam

it will be d) 14.4W

Explanation:

potential difference (v) = 12 volts

resistance (r) = 10 ohms

now, we know

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
