Yah, all I was doing was taking a spliced wire and putting in a switch. When I said it didn't work I just meant that when I flip the switch, nothing happens. I realized I was using the portion of the switch that was rated for 3 amps @ 250 V instead of 6 amps @ 125 V. However, the switch didn't...
I'm in the process of repairing a lamp that I found with a broken switch. I know the lamp mechanism is functioning because I've bypassed the switch and plugged it in and it works fine. I needed to buy a new switch and they all have a current rating. I'm using 1 60 W bulb with a standard North...

Hey everyone,
I'm currently running a program which accepts an input file. The input file has various parameters, 3 of which I need to change, run again, etc.
The range of those 3 parameters are 15 values for one, 12 values for another and 10 for another, so I have 15*12*10 (=1800) possible...
Homework Statement
Taking the equation of motion for a rocket launched from rest in a gravitational field g, m\dot{v} = -\dot{m}v_{ex} - mg , and knowing that the rocket ejects mass (fuel) at a constant rate \dot{m} = -k (where k is a positive constant), so that m = m_{o} - kt . Solve...
Thanks! So the integration is from m to m initial, correct? That gives me the result the textbook has. Thanks a bunch! I knew it was simple, but it's literally been 2 years since I've taken Calculus.

Hi,
I was going through a fairly simple proof about rockets/momentum, taking into account the changing mass of the rocket as well as the velocity of the exhausted fuel. I was getting towards the end of it having felt like I understood it well, until I got to this point (this is from a Junior...
