Does air expand when heated? As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. What expands the […]
What are the 2 different types of battery cells?
What are the 2 different types of battery cells? Basically, all the electrochemical cells and batteries are classified into two types: Primary (non-rechargeable) Secondary (rechargeable) Can I use cr1220 instead of CR1225? As one can see, in most situations BR1225 and CR1225 batteries are interchangeable. Is CR1225 same as BR1225? The BR1225 is designed for […]

Does power increase with frequency?
Does power increase with frequency? If the waveform is symmetrical, there is no frequency dependence of the power. But for a non symmetrical one, the power will, sually increase with directly with frequency. Is 60Hz more dangerous than 50Hz? Low-frequency (50- to 60-Hz) AC is used in US (60 Hz) and European (50 Hz) households; […]

How does electric motor in generator work?
How does electric motor in generator work? When an electrical current is applied to the motor, the magnets or windings create a magnetic field that both attracts and repels the rotor, causing it to spin. Rather than using electricity to create motion, electric generators in Lethbridge convert mechanical energy into electrical energy. What are the […]
What is the distance between two stars called?
What is the distance between two stars called? Parsecs: Many astronomers prefer to use parsecs (abbreviated pc) to measure distance to stars.
