Hello All, I am currently taking Signal Processing & Linear Systems. I've come across my last problem for homework but can't find a way to do it. If someone can show me in the right direction it will be very helpful. Thanks The Problem: The voltage f(t) = 2u(t) is applied to the circuit...

Heres the problem: An infinite nonconducting sheet has a surface charge density of 5.80 pC/m^2. How much work is done by the electric field due to the sheet if a particle of charge q = 1.60x10^-19 C is moved from the sheet to a point P at distance d = 3.56 cm from the sheet? Also if the...

hello all, I was looking for the equation for the shell therom. general expression for the magnitude of the gravitational force but the one were the one sphear is inside the other, such as a person on the earth.

what equation would that be, i don't know one that's called curviliear motion equation. i know these equations: angular position angular velcoity - i would guess to use this but there's not rad given. angular acceleration

I tried using equations useing different methods of solving this problem but no cigar. If anyone can help me just to get started that would be grand. Thanks A spaceship negotiates a circular turn of radius 3890 km at a speed of 33860 km/h. (a) What is the magnitude of the...

but how would i solve out for m2 or v2 when the equation has both in it? Does v2f = v1i - v1f ? Edit: I got it now thanks a lot !

looks like you go to PENN STATE Physics 211 212 213 214 SORRY I CANT HELP, but i thought your class looked like a penn state class 214, just got me happy! sorry lol

Hello All, I have a question that i can't seem to get. If someone could help me get started on part a that would be great. So far i have tryed using P =m1v1 and can't seem to find any other equations that would help with the problem. Any help is great! Thank You Problem: A cart...

No question a is correct i already put it in webassign, (a online physics homework thing for college). for b i just asked my professor, it was pretty simple. Using F = ma F = Fnet while in motion Thanks anyway dude :smile:

So no ones going to help me, thanks alot

still no post ?

Ok so i found a) by using T = mg*u / cos x + sin x * u yielding => 282.23 Newtons, trying to find B) can anyone help? EDIT: Just a little help to get me moving is good enough, PLEASE SOMEONE HELPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP

Hello everyone, I have have no clue on how to go about this problem here, if someone can explain how to go about these it would be great! THANK YOU ALL! Problem 1: A 62 kg crate is dragged across a floor by pulling on a rope attached to the crate and inclined 15° above the horizontal. (a)...
