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...
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 :

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...
