Physics After long periods of use, a grey spot develops on the inside of a bulb. This is because Dust inside the bulb condenses on the top The heat of the bulb scorches the glass at the top The tungsten filament evaporates and collects there Glass undergoes a change due to the heat Dust inside the bulb condenses on the top The heat of the bulb scorches the glass at the top The tungsten filament evaporates and collects there Glass undergoes a change due to the heat ANSWER DOWNLOAD EXAMIANS APP

Physics Planets do not twinkle because They are very far away from the earth resulting in decrease in intensity of light They emit light of a constant intensity Their distance from the earth does not change with time They are nearer to earth and hence we receive a greater amount of light.

Physics Why are we able to hear short wave broadcasts better than long wave broadcasts ? Short waves are more energetic than long waves. Short wave broadcasts are made by nearby radio stations. By convention, short waves are meant for long distances, whereas long waves are reserved for short distances. Short waves are unaffected by atmospheric disturbances.
