Suppose that t and v are the kinetic and potential energies, and and momentum. and p are the position (a) prove that [pq, r where p, q and r are operators p[q, r] + [p, r\q, _ (b) show that [f(x), p] = ih dr for an arbitrary function f(x) (c) show that (xp) 2 (t) (1) dt dr (d) show that the left side of eq. (1) becomes zero in a stationary state to obtain dv 2 (t) dar which is called the virial theorem. (e) use the virial theorem, prove that (t) = (v) for stationary states of the harmonic oscillator

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
