"If you travel from earth in 99.99% the speed of light for one year (from earths perspective) how long would you perceive the trip to be?" Basically we use something called the Lorentz Factor to …

## What is air? (Gas composition combination)

Could you survive inside a whale? Would lighting a match cause an explosion? Was reading an article that was somewhat ridiculous and somewhat interesting at the same time. In the comments, …

## Circuits Complex Analysis Equation Simplification

You want a common denominator to simplify things. I replaced jw x 10^-5 with the variable X, so I didn't have to write it as many times. You can factor out a term later on that cancels. 10^5 …

## Tutoring Physics, some basics about circuits

We looked at circuits with resistors. Saw current, voltage, and resistance. The circuits included branches. Current is the flow of electrons. Electrons have a negative charge. Used Ohm's law, V …

## “How cold would a sphere of silver with a radius of 5 meters be in order to freeze the ocean upon contact?”

Short answer is "no". There is a lower limit to how cold something can be, absolute zero. It looks like the specific heat of silver is 0.233 J/gm K ( at 20 C). Let's say it stays that value …
