Which item will sound travel faster? Solids: Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air. Why […]
What force acting on an area of 0.5 m2 will produce a pressure of 500 Pa?
What units are used for W?

What does neutrino mean?
What does neutrino mean? A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero. Neutrinos are one of the most abundant particles in the universe. Because they have very little interaction with matter, however, they are incredibly […]

What is the wavelength of the first harmonic?
What is the wavelength of the first harmonic? For the first harmonic, the length of the string is equivalent to one-half of a wavelength. If the string is 1.2 meters long, then one-half of a wavelength is 1.2 meters long. The full wavelength is 2.4 meters long. What is a harmonic wave? A harmonic is […]
Can I reverse a transformer?
Can I reverse a transformer? When a transformer is reverse fed, the taps move to the output side and so their operation is reversed. For reverse fed applications, raising the taps will increase output voltage and lowering the taps will lower output voltage. What is the difference between step up transformer and step down transformer? […]
What are the disadvantages of LED bulbs?
What are the disadvantages of LED bulbs? What are the disadvantages of LEDs? High up-front costs. Transformer compatibility. Potential color shift over lamp life. Performance standardization has not yet been streamlined. Overheating can cause reduced lamp life. Why do my LED lights glow after being turned off? Why Do LED Bulbs Glow When Off? An […]
What does heat do to MS?
What does heat do to MS? MS causes nerves to lose their myelin sheath, making them more vulnerable to heat and temperature changes. Heat exposure can cause or heighten fatigue, numbness, blurry vision, tremor, confusion, imbalance, and weakness. This is a pseudo-exacerbation as symptoms typically dissipate once the body is cooled. Does MS get worse […]
