F1=normal force
F2=gravitational force on the bulb
net force=F1+F2
but f1 and f2 are same in magnitude but differ in direction.(newton 3rd law of motion)
If we add both f1 and f2,they will cancel out
Therefore ;
The net force=f1+(-f2)=0
So,the net force on the bulb is 0N
The weight of the bulb, acting downward, and the tension in the cord, acting upward, must be equal, so that the net force on the bulb is zero. If not, then the bulb is accelerating in the direction of the net force. If it's just hanging there and not accelerating up or down, then the two forces must be equal, and add up to zero.
If the voltage is appropriate, the bulb will shine.
The paper is in the domed arch where the light bulb hangs down. Climb the electric cord to grab it.
If there is just one light out, the bulb probably burnt out and needs to be replaced. A single bulb will not have a fuse.
No, an incandescent bulb i.e. a bulb that emits light by the generation of heat, emits white light and is therefore not monochromatic. For a source to be monochromatic, the light emitted must be of a single wavelength.
The light bulb was widely accepted and may have been the single most popular invention of all time - although there have since been several alternatives such as the fluorescent tube and the LED, which are in the process of replacing the light bulb.
yes, it can be used - single phase voltage of 230v. 50HZ is important
Rear combination light assembly contains three bulbs. Two bulbs are single-filament and are used in hazard/turn signal and backup light circuits. Third bulb is a dual filament bulb; one filament functions as brake light and other as tail light. A plastic bulb holder mounts three lamps and associated wiring. Bulb holder can be removed from inside vehicle for bulb replacement.
It is dependant on whether the switches are in wired in a parallel or series configuration. If the switches are wires in parallel then both switches would have to be off to turn the light bulb off. Either switch could turn the light bulb on. If the switches are wired in series then both switches would have to be on to turn the light bulb on. Either switch could turn the light bulb off.
Thomas Edison is best-known for the light bulb.
No. The light bulb is two words, not a combination of light and bulb.
