i guess the crux of my argument is whether the area under the v(x) curve can be used in this manner, comments?

Homework Statement Consider a particle moving back and forth on a frictionless parabolic bowl, y = ax2, where a = 1.460 m-1 If the particle is released from rest at the point on the bowl at b = 0.43 m, find the period of the oscillations. I have an equation for velocity(as a function of...

can anybody recommend a book for electrical engineering? i want to learn all the components and be able to read a circuit diagram. something like this (geiger-counter) http://www.imagesco.com/articles/geiger/schematicl.jpg

Found my error. since the ships are approaching each other, the equation was u=\frac{v-u'}{1-\frac{u'v}{c^{2}}} then substituting -v = u \frac{u'u^{2}}{c^{2}}+u'+2u=0 which yields the correct answer of 1.8326x108 m/s

i accidently posted this before adding my work, ill get it on in a moment

Homework Statement Two spaceships approach each other, each moving with the same speed as measured by an observer on the Earth. If their relative speed is 0.89c, what is the speed of each spaceship as measured on Earth? Homework Equations u=\frac{u'+v}{1+u'v/c^2} 3. My work so ship A...

Homework Statement Supose that a traffic study measures the speed at which people drive on the highway, and determines that the situation is well modeled by the probability distribution P(v)=Cv4e-v/vo. (a) If we are to measure speeds in mph, give the appropriate units for C and vo. (b) In...

A small loop of area A is placed inside a long solenoid that has n turns per meter and carries a sinusoidally varying current of amplitude i. The central axes of the loop and solenoid coincide. If i = i0sin ωt, find the emf in the loop. EMFinduced = - d(\phiB)/ dt \phiB=BA Bsolenoid=...

edit* I'm starting my freshman year as a physics major this fall and was wondering which would suit my needs better, a mac or a pc?

I'm starting my freshman year as a physics major this fall and was wondering if a pc or a mac would suit my needs. also, what programs besides ms word and excel would i need?

if part c is asking for a graph of E as a function of r, from origin to a =zero from a to b =zero from b to c =zero from c to d decreasing 1/r^2 this is the only thing i can conclude based on the field within a charged sphere being equal to zero

In regards to the FRQs of Electricity and Magnetism, for number one, how would you determine the charge induced on the inner and outer surfaces? is it simply a matter of surface area? im not allowed to post the url, but the questions are available at...
