What are sound waves created by?
What are sound waves created by? Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium. What happens to sound waves in […]

What happens if you put a conductor in a capacitor?
What happens if you put a conductor in a capacitor? Originally Answered: When a conductor is placed between the plate of a capacitor, then what is the effect on its capacitance? Inserting an otherwise unconnected conductor introduces an isopotential surface. If it is inserted in an existing isopotential plane, it has no effect. Otherwise the […]
What will happen if the Earth suddenly stops rotating?
What will happen if the Earth suddenly stops rotating? At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes. What is […]
What is the difference between sampling with replacement and without replacement?
What is the difference between sampling with replacement and without replacement? What’s the Difference? When we sample with replacement, the two sample values are independent. Practically, this means that what we get on the first one doesn’t affect what we get on the second. In sampling without replacement, the two sample values aren’t independent. What […]
Which type of washing machine consumes less water?
Which type of washing machine consumes less water? As a front loader uses less water, there is significant energy or electricity saving as much less water is heated. Also, front loaders dry up the cloths to a significantly higher degree (as less water is used), the dryer cycles are much shorter, thus saving electricity on […]
Why is Gillnetting illegal?
