Consider a one-dimensional collision at relativistic speeds between two particles with masses m1 and m2. Particle 1 is initially moving with a speed of 0.717c and collides with particle 2, which is initially at rest. After the collision, particle 1 recoils with speed 0.495c, while particle 2 starts moving with a speed of 0.279c. What is the ratio m2/m1?

An electron’s rest mass is 0.511 MeV/c2.

Two rigid tanks are connected by a flow valve. Tank 1 has a volume of 0.3 m^3 and contains carbon dioxide at 60 degrees C, 0.6 MPa. Tank 2 is initially empty. The valve between the tanks is opened and the gas flows into Tank 2 until a condition of 27 degreesC, 190 kPa is reached in that tank. This process causes the condition in Tank 1 to change to 0.3 MPa, 50 degrees C. Determine the volume of Tank 2.

A flexible device is filled with oxygen at 200oC, 600 kPa. The initial volume in the device is 0.02 m

The oxygen then expands according to the mathematical relationship P·V^1.2 = constant until the

temperature is 100oC. Determine the final volume and pressure of the oxygen.

A bar with a 2.375 inch x 0.188 inch cross section that is 11.25 inches long is known to have a Poisson ratio of 0.3. If the bar is loaded so that it becomes 11.31 inches long, what will the final cross sectional area of the bar be?

True or False: All possible resonance structures contribute equally to the resonance

hybrid.

Prove the following statement:

If each of x,y, and w is an element of V(supscript 3), then x+(y+w)=(x+y)+w

My hard drive got damaged recently, so I went about buying a new hard drive and I just installed Windows 7 Professional on the hard drive.

My computer is a Sony Vaio, model: VPCCW21FX

My question is if it is necessary to download any drivers after installing Windows 7. I've heard I can download them from the Sony website, but I've tried looking with no results. I want my Vaio to be in the same condition it was when I bought it, and after installing Windows I am lacking certain programs such as "Vaio Care" and stuff like that. So, does anyone have something to say?

A projectile is launched from a cannon; it has an initial speed of 56 m/s at an angle of 69 degrees above horizontal. The muzzle of the cannon is 1 meters above the ground. How far down range will the projectile land?

A block of steel (density = 7.9 g/cm^3) measures 4 inches x 10 inches x 40 inches and is moving at 364 feet per minute. Find the momentum of the block in kg*m/s.

Can someone show me how to do this?

Solve the following simultaneous equations for x, y, and z;

3x + 2y + z = 5

x - 7y + 12z = -7

4x + 5y -2z = 4

In Modern Warfare 3 there is a title called "SayHiToUrMom", and I can not find out how to get it anywhere. I have seen people in the game with this title, but it's not on the internet. Can anyone help?

A 79.0 kg student is standing atop a spring in an elevator as it accelerates upward at 3.80 m/s2. The spring constant is 2100 N/m. By how much (in m) is the spring compressed, assuming that the local acceleration due to gravity is 9.80 m/s2?

Does anyone know where I can find a costume? This is urgent.

A low-pass RC filter with a crossover frequency of 1910 Hz uses a 152 Ω resistor. What is the value of the capacitor (in uF)?

A proton traveling at a speed of 5.38 *10^6m/s enter the gap between the plates of a 2.76 cm wide parallel plate capacitor. The surface charge densities on the plate are +/- 8.38 *10^-6 C/m2. How far (in m) has the proton deflected sideways when it reaches the far edge of the capacitor? Assume that the electric field is uniform inside the capacitor and zero outside

An electron in a uniform electric field increases its speed from 3.180E+7 m/s to 6.360E+7 m/s over a distance of 4.74 cm. What is the electric field strength (in N/C)?

Two circular disks spaced 6.42 mm apart from a parallel-plate capacitor. Transferring 2.25 *109 electrons from one disk to the other causes the electric field strength to be 2.42 *105 N/C. What are the diameters (in m) of the disks?

A 4 nC charge is at the origin and a -5 nC charge is at x = 5 cm.

At what x-coordinate could you place a proton so that it would experience no net force?
