One beam of coherent light travels path p1 in arriving at point q and another coherent beam travels path p2 in arriving at the same point. if these two beams are to interfere destructively, the path difference p1 - p2 must be equal to one beam of coherent light travels path p1 in arriving at point q and another coherent beam travels path p2 in arriving at the same point. if these two beams are to interfere destructively, the path difference p1 - p2 must be equal to an even number of half-wavelengths. a whole number of half-wavelengths. a whole number of wavelengths. zero. an odd number of half-wavelengths.

Awind turbine is initially spinning at a constant angular speed. as the wind's strength gradually increases, the turbine experiences a constant angular acceleration 0.173 rad/s2. after making 2870 revolutions, its angular speed is 132 rad/s. (a) what is the initial angular velocity of the turbine? (b) how much time elapses while the turbine is speeding up?

Africtionless piston-cylinder contains 50 l of saturated liquid r-134a. the piston has a mass and an area resulting in an applied pressure of 500 kpa on the refrigerant. the refrigerant is now heated until its temperature rises to 70∘c. calculate the work (in kj) done during this process.
