<span>when voltage is high say 100V than the light will be a lot dimmer than design because the light is usually designed to be operated at 240V . If the supply voltage to the bulb is 100V, the filament dissipates 34.7W power and thus the temperature of the filament will be less and hence the bulb does not produce so much light .</span>
Answer:
D. not enough information to decide
Explanation:
i dont understand >.<
Answer:
Bonds have been broken that held particles in place
Explanation:
Boiling took place with use of thermal energy(heat energy), this will make particles to move faster and apart from each other bcos temperature is increased. Increase in temperature causes increase in kinetic energy
Answer:
"When neutral objects are brought near the sphere, they are attracted to the sphere before they touch each other."
Explanation:
Charging by induction is said to occur when an uncharged object is brought near a charged body and it gets attracted towards it without even the two bodies touching.
The charged body polarizes the uncharged body. The charges shift to either sides and that causes the force of attraction between the two.
Suppose a negatively charged body is brought close to an uncharged body. The electrons of the body repel from the side near to the charged body and shift to the other end leaving behind positive ions.
The last line of the given paragraph indicates that charges can be moved by induction.
