I have a similar problem where I am told to find the total deflection I have derived the following equations delta Y = Y(in capacitor) + Y (in the distance after the capicator to the screen) = (.5*(eE/me)(Lof cap/V0)2)+((eE/me)*(Lof cap/V0)(Dto screen/V0)) ok now assuming that, that is...

I got it... It came out to be that the Carnot engine can never be 1 and the ones i had before Thank you for your help... I know it's been a bit frustrating Thank you

Yeah you got the direction of the forces... So what you have in essence is http://geocities.com/hackers_007_008/Untitled.jpg

Draw a free body diagram for the mass, the upward/downward forces and the left/right forces... what keeps the mass from sliding up and down and what keeps the mass from going through the wall...

No problem... anytime

v = 8.9443 m/s right... so 2 x 8.443? + 8 x 0 = 2 + 8 x vf But everything else seems good.

you're close... can you write down exactly what you're doing so I know where you're going wrong

whats your reasoning behind doing that? Think about it like this, the first mass has kinetic energy initially. now it strikes the second mass and they "stick together"... so in this process of sticking energy is lost to heat, bonding etc... but the momentum is conserved since there isn't a...

p=mv where p is the linear momentum the conservation of linear momentum says where u signifies vector velocity before the collision v signifies vector velocity after the collision. For an inelastic collision

Since there is no net external force on the system, the momentum is conserved... and since it's also a elastic collision energy is also conserved. The easiest way to go about this problem is to use conservation of linear momentum another way of going about this is that since energy is...

It's still coming out wrong Andrew, I tried both what you posted and what you suggested about the adiabatic expansion. THE FOLLOWING ARE WHAT I MARKED TRUE Adiabatic expansion will lower the temperature of a gas The entropy of the universe can never decrease A refrigerator lowers the...

The COP (coefficient of performance) of a refrigerator can never be greater than 1 (F) If the temperature of the cold reservoir increases with the temperature of the hot reservoir unchanged, the efficiency of a Carnot engine will increase (F) The entropy of a system can never decrease (F)...

Yeah that's what I did... sorry about that, I must've gone wrong copiying and pasting... SO this is what I have at the moment and its wrong: All Carnot engines are more efficient than all real engines T The COP (coefficient of performance) of a refrigerator can never be greater than 1 The...

Hey I tried your suggestions there's something else wrong... Any process that includes adding heat to an ideal gas will increase the entropy of the gas(T) Adiabatic expansion will lower the temperature of a gas F If the temperature of the cold reservoir increases with the temperature...

Homework Statement WHICH OF THESE IS TRUE: The entropy of the universe can never decrease All heat engines operating between the same temperatures have the same efficiency Any process that includes adding heat to an ideal gas will increase the entropy of the gas All Carnot engines...
