Thanks so much Adder_Noir ! That's a lot more than I could come up with, so I don't think we'll look like complete idiots when we present it... :)

Hi, For an electronics project, my friend and I created this circuit that we found online: http://www.redcircuits.com/Page72.htm" We had no problem putting it together, but we’re not really sure how it works. Our professor wants us to have at least a basic understanding when we present...

Thanks Astonuc-- my results seem much more realistic now :)

I'm not sure if I'm approaching these problems correctly. Could someone check my work? Steam at 100°C is condensed in 500g of water at 20°C. a. What is the maximum amount of steam that can be condensed in this amount of water? Q[steam] = m[steam] * L[c steam] * (T[f] – T[i]) Q[steam]...

I'm having trouble solving this one: Two motorcycles are traveling in opposite directions at the same speed, when one of the cyclists blasts her horn, which has a frequency of 544 Hz. The other cyclist hears the frequency as 563 Hz. If the speed of sound in air is 344 m/s, what is the speed...

Ok, I'm not sure if I understood, but I've reworked the problems: For this problem, I hope I used logical mathematics and not contrived black magic... 4. A block attached to a spring with unknown spring constant oscillates with a period of 2.0 s. What is the period if : T =...

Hi, I'm having trouble with this problem because I don't know how to deal with all these unknowns: 4. A block attached to a spring with unknown spring constant oscillates with a period of 2.0 s. What is the period if : a. The mass is doubled? b. The mass is halved...

Hi, I’m having a really difficult time in physics, and I need some help on this homework assignment. Here are the questions and the work I’ve done. I really don’t know how to approach them, and at this point, I’m just kinda throwing equations at them haphazardly… 5. A 175 kg weather...
