    What Is the Correct Work Done in This Thermodynamic Cycle?

    no, i actually don't know what the correct awnser is, but today after asking my professor he said that the correct awnser will be to graph those values on a pV graph and to get the area under the curve(or the area of the square it forms with those values) can anybody explain to me what is wrong...

    What Is the Correct Work Done in This Thermodynamic Cycle?

    Thermodynamics Question (What did I do wrong?) Problem 19.46 Two moles of N2 gas undergo the cycle abcd. The pressure of the gas in each state is: pa = pd = 5700 Pa ;pb = pc 1700 . The volume of the gas in each state is: Va = Vb = 2.40 ;Vc= Vd 8.50 . The gas may be treated as ideal...

    Solving the Sound Wave Problem of Two Identical Violin Strings

    ummm just ran into another problem in this question, for the third part "by what fractional amount was the string changed?" Iam using that the fundamental frequency of a string is proporional to the velocity of the waves which is proportional to the square root of the Tension in the...

    Calculating Displacement and Speed in a Standing Wave on a String

    Adjacent antinodes of a standing wave on a string are a distance 14.5 cm apart. A particle at an antinode oscillates in simple harmonic motion with amplitude 0.850 cm and period 8.00×10-2 s . The string lies along the + x - axis and is fixed at x = 0. Find the displacement of a point on the...

    Solving the Sound Wave Problem of Two Identical Violin Strings

    thanks a lot, lol for some reason i had the equation with a plus sign, thanks for the hint if it wasent for you i would be stuck here all night.

    Solving the Sound Wave Problem of Two Identical Violin Strings

    Two identical violin strings, when in tune and stretched with the same tension, have a fundamental frequency of 440.0 Hz. One of the strings is retuned by adjusting its tension. When this is done, 1.5 beats per second are heard when both strings are plucked simultaneously. -What is the...
