Homework Statement 1.0 mol of a monatomic ideal gas is taken through the cycle in the figure below. http://s1142.photobucket.com/albums/n603/bdoneski/?action=view&current=20-26.gif" a) What is the following as the gas goes from state a to state c along path abc? W0/P0V0 (b) What...

nevermind i solved it

Figure 20-29 shows a reversible cycle through which 1.00 mol of a monatomic ideal gas is taken. Assume that p = 2p0, V = 2V0, p0 = 1.13*10^5 Pa, and V0 = 0.0235 m^3. Fig. 20-29 http://s1142.photobucket.com/albums/n603/bdoneski/?action=view&current=hrw7_20-29.gif" (a) Calculate the work done...

constant pressure

Homework Statement When 23.3 J was added as heat to a particular ideal gas, the volume of the gas changed from 54.7 cm3 to 100 cm3 while the pressure remained at 1.00 atm. (a) By how much did the internal energy of the gas increase? J (b) If the quantity of gas present was 2.00 10-3...

the second harmonic has three nodes

Homework Statement A rope, under tension of 120 N and fixed at both ends, oscillates in a second-harmonic standing wave pattern. The displacement of the rope is given by y = (1.18 m)sin ( x / 2) sin (10 t), where x = 0 at one end of the rope, x is in meters, and t is in seconds. (a)...

Homework Statement A 140 g wire is held under a tension of 200 N with one end at x = 0 and the other at x = 7.0 m. At time t = 0, pulse 1 is sent along the wire from the end at x = 7.0 m. At time t = 30.0 ms, pulse 2 is sent along the wire from the end at x = 0. At what position x do the...

yes everything looks good, the diameter is 63.1 cm

Homework Statement A simple open U-tube contains mercury. When 12.3 cm of water is poured into the right arm of the tube, how high above its initial level does the mercury rise in the left arm? Homework Equations density of water=1000kg/m^3 density of mercury=13534 kg/m^3 The...

it says that my answer is incorrect, I multiplied 32.998 by 2 and got 65.996, but its not correct

wow lol, thank you for all the help you are a life saver.

Fb=1475.2136N/9.8=actual mass of sphere mass of sphere=150.532 mass whole iron sphere-mass of actual sphere=mass of inner sphere=1184540.665 7.87=1184540.665/V rinner=32.998 cm but that's incorrect, where is my error?
