Sorry about this. I'll get some sleep and rethink the question. Thanks for the help anyway :D

C. Using one of the three laws of projectile motion. It obviously can't be A as it doesn't have Distance in it. It can't be B because that doesn't have time in it and D doesn't even hold acceleration. Therefore C is the right answer you would just need to re-arrange the equation to get a...

I'm just really trying to understand this equation: V = IR I have an example here where someone used it to find the total resistance of their resistor on their circuit. For example. A 12 volt battery connects to a 2 Ohm resistor. How would you calculate the total resistance made by...

Homework Statement I'm currently trying to find the total resistance of my resistors in my curcuit I have designed. Homework Equations I'm using the equation V = IR, where V = Potential difference in volts, I = Current in Amps and then there's R... It's a constant of sorts but I...

HUGE THANKS I LOVE YOU!

Haha! Took me a couple of seconds to get the second one.

I've been asked to make a simple circuit design for a physics class. Basically, I'm looking for something like this: http://ourworld.compuserve.com/homepages/Bill_Bowden/page5.htm#eyes.gif I need something with an item list and a guide as to how to connect it... needs a diagram etc...

I've currently got an assignment for a basic physics class. The job to be done is that I need to create a simple circuit that holds some use in society. It doesn't need to be too complicated but I've been stuck on finding a decent website that I could get a circuit schematic/build instructions...

Just have to get a picture box to move around a screen, I'm running the program by a timer. I'll show set integers below. Timer = Timer1 Picture Box = Robot Dim Robotpace as integer Basically, when you click on the start button it enables the timer. Here's the coding. Private...

This depends, is it just a fraction of the speed of light (as obviously nothing can travel at it bar light itself), and for how long? Either way, you can use this formula to equate Proper time to Earth's time: t = to/sq[1-v^2/c^2 So for example, Bazza jumps in his crazy new spaceship and...

Homework Statement Having some problem with this question: The threshold fequency for a material is 5.0*10^14 Hz. Find (a) the work function and (b) the maximum velocity of electrons ejected by radiation of frequency 8.0*10^14 Hz. The mass of an electron is 9.1*10^-31kg. Homework...

Thanks, I just realized I wasn't calculating both horizontal and vertical attributes. Can't believe I missed that! Thanks again :D

Homework Statement I'm looking at trebuchets. Basically, a trebuchet shoots a projectile with an initial velocity of 30ms-1 at an angle of 55, 65 and 75 degrees. Friction/Wind resistance do not account. I need to find the maximum height reached, the time the projectile spends in the air...

Homework Statement I've been asked to complete a report on an ancient weapon (Trebuchet chosen) for a final year paper. Basically its to be structured like this: - An introduction including a brief history of the ancient weapon i.e where it was used, why etc. - An explanation of the...

I'm currently in my final year of high school, doing physics. We have been given an assingment about bridge structures. Basically, we build a bridge out of spaghetti, test it and discuss it. I'm thinking of things in which I can talk about. I've built an Arch Design Bridge. Mainly due to...
