I read it like this: You decide (up front) how much you want to pay. Then they start flipping the coin till it lands heads. Count how many times you flipped it, and they pay you 2^n dollars. I'm not sure if it lands heads on the first try do you get nothing or 2 dollars, though. It says "lasts n...

I think to answer the last question, more justification should be given than just "that's too many zeros." Say "that's about a trillion dollars," and note this is on the order of the largest corporations' valuation. But no individual has that much money. Something about the game though - why...

There is something else going on with digital cameras - they can capture light outside what humans can see, but then display that light as visible light. You can see this if you point your phone camera at a TV remote and push some buttons on the remote. In the phone display, you can see the...

Are you working with it in the time domain? If so, you'll need to perform a Laplace transform. I'm not sure how Maylab does that (it's been awhile) but they have help and a forum. Also, you could use Maple or probably Mathematica to do this, as well.

Matlab has a symbolic package, which can help with arranging formulas, when working on the derivations. I would create some free body diagrams to account for the forces and motions involved to start. An inverted pendulum can be balanced with just a moving cart. Once you have that solved then...

I guess that is a header we should place on any listing - where you are willing to ship and who pays shipping. It could be that 2 people in the same region (outside North America) connect.

We just added one of these at our business as a backup. We were on Comcast for our internet, phones and TV, but the price kept rising. In March we switched to AT&T fiber optic and were impressed with the speed increase. In July a truck snagged the AT&T fiber line and we were down for 2.5 days...

I'm not sure which type of axle would be better, but could you have one of each? One type on front and one on back. Just thinking. Try some free body diagrams of how you think the forces would act on each style of axle. Think about how a disturbance or imbalance would affect each style. If you...

The amounts in your column T are a geometric sequence with ratio = 1.06 There is a formula for the partial sums of the values of a geometric sequence. See this for more information: https://www.mathsisfun.com/algebra/sequences-sums-geometric.html

Looking at this again, this almost looks like a life insurance policy that you might get on a loan. If the borrower dies, then the balance of the loan is paid off - hence the declining payout.

Have you tried plotting these values? Try both column S and T versus the age. Hint, you don't need to key in every value. Another hint: I left out the value at 55. Desmos.com has an interactive linear regression calculator that can help figure out a formula.

Thanks for all of your contributions @fresh_42

Welcome. Many people have setbacks. I know something about it. It is not the end of the road, but may redirect your path. For the other university- do you know anybody who goes there? If it were me, I would want to visit to learn about the programs and the environment there. Good luck!

I think there is not enough information to consider change in kinetic energy. So we could assume it is "slow enough". You could think of an imaginary level trough at the top, long enough to hold all of the mercury. Once mercury is in this trough, no more potential energy is added. One question -...

Welcome to PF! You will find that there is more than just physics here.
