Yes, this was what I meant. With respect to time t. I have already figured a. out I did the derivative of D(x,t). The answer I got and believe is correct is, ##\frac{100vD_0}{2(a*0.01)^3}## I still don't know how to do b. though.

Homework Statement A wave pulse on a string is given by D(x) = D[0][/SUB]/(x[2][/SUP]+a[2][/SUP]), where D0 is a constant with units of cm3 and a is a constant with units of meters. a. If the wave moves along the string at a velocity of v in cm/s, what is the transverse velocity of particles...

In a isobaric process W=PΔV I Given the change in temperature and pressure is constant to find heat added to an mono-atomic ideal gas we use Q=ΔU + W = 3/2 nRΔT + PΔV = 3/2 nRΔT + nRΔT so Q=5/2 nRΔT correct? II But given the heat added to an ideal gas, constant pressure that acts on the...

An ideal gas at initial state has temperature 300 K has been compressed under constant pressure of 30 Pa from volume 3 cubic meters to 1.8 cubic meters. In the process 75 J of heat was lost. A. Find the change in internal energy B. Find the final temperature I tried two methods in A and they...
