Homework Statement A particle's four momentum in a given inertial frame is [E,Px,Py,Pz]=[5 J, 5 N*s, 0, 0]. What is its four-momtenum in an inertial frame that moves in the +x direction at a speed of .8 c relative to the first frame?Homework Equations N/aThe Attempt at a Solution Isn't the...

Masteringphysics told me to use 1000C for furture calculations in the problem, hence why it I got it wrong... And 17.3 cm^3, so it's not larger.

Hahahaha, WOW. I hate masteringphysics. I just wiki'd Adiabatic process and found the simple equation VT^{\alpha}=Constant Where \alpha=5/2 for diatomic gases (like air). I found V_{f} to be 17.3, but that was wrong because my temperatures weren't accurate enough. Guess what though...

I meant PV^y stays constant throughout the adiabatic process. I guess it should be P1V1^y=P2V2^y. What do you mean by the "correct" equation for the adiabatic process? Also, I know the final temperature is the correct answer, but what I did was: W=nCv(deltaT) n=PV/RT n=(101325)(.0006)/8.31(308)...

The second one should be (-71.4x + 51y 78z). So yes, you got them both right.

10.37 degrees is the right answer. You're welcome. EDIT: I would also note that theta could actually be another value too, but the one you got is the most efficient and most direct.

Two big hints I will give you: You want your max height of the bullet, in the y direction, to be 150m, where the target is. Assuming 150m is your max height, what does that tell you about the velocity of the bullet, more specifically Viy and Vfy? With that in mind, what does the equation...

Homework Statement One cylinder in the diesel engine of a truck has an initial volume of 600 cm^3. Air is admitted to the cylinder at 35 C and a pressure of 1.0 atm. The piston rod then does 500 J of work to rapidly compress the air. What is the final temperature and volume? I found the final...

After much observation, I was wrong to conclude pressure would be the same. After reading the hint carefully, I came to the conclusion pressure changes, while volume remains constant. Still, I don't know how to find the pressure of the system.

It's possible to find the K value. The total mechanical energy of the system has a constant value equal to the potential and kinetic energy of the system. K + U = E In SHM, Energy is also equal to .5kA^2 That would mean... K+U=.5kA^2 Is there a way to make the kinetic energy or potential energy...

Homework Statement The mercury manometer shown in the figure is attached to a gas cell. The mercury height h is 120 mm when the cell is placed in an ice-water mixture. The mercury height drops to 30 mm when the device is carried into an industrial freezer. HINT: The right tube of the manometer...

You're pulling it up though, not pressing it down, if that makes a difference. Also, I'm slightly confused because how can the buoyant force equal the restoring force if the there's already part of the cylinder in the water. The length of the cylinder in the fluid isn't just dy. Wouldn't it be...

Homework Statement A cylinder of density RhoO, length L, and cross-section area A floats in a liquid of density RhoF with its axis perpendicular to the surface. Length h of the cylinder is submerged when the cylinder floats at rest. Suppose the cylinder is distance y above its equilibrium...

Homework Statement A television channel is assigned the frequency range from 54 MHz to 60 MHz. A series RLC tuning circuit in a TV receiver resonates in the middle of this frequency range. The circuit uses a 16 pF capacitor. Inductor is .487 micro Henries. In order to function properly, the...
