One mole of an ideal diatomic gas at room temperature undergoes a transition from a to c along the diagonal path in Figure 19-23. (a) During the transition, what is the change in internal energy of the gas? -4987 J (b) How much energy is added to the gas as heat? ____ J (c) How much heat is...

Is that Bernoulli's equation? The one in my book is different.

I have to do this question too. How do I find the velocity w/o knowing the time?

OH! I get it now.. 360deg/60sec x 2pi rad/360deg = 0.105 Thanks for the help =]

360deg/1min = 360deg/60sec = 6deg/sec x 1rad/180deg = 0.03 rad/sec?

hmm, those were all wrong.. i don't know

(a) What is the angular speed of the second hand of a smoothly running analog watch? ____ (rad/s) i got 0.03 pi webassign says "Check the syntax of your response" i also tried 0.03, but it's wrong also.. how do i put my answer?

i got Vf = 23.84 Do I plug in the y-component of Vf?

A 78 kg skier starts from rest at a height of H = 29 m above the end of the ski-jump ramp (Figure 8-39). As the skier leaves the ramp, his velocity makes an angle of 28° with the horizontal. Neglect the effects of air resistance and assume the ramp is frictionless. (a) What is the maximum height...
