A screen is placed 51.0 cm from a single slit that is illuminated with light of wavelength 677 nm. If the distance between the first and third minima in the diffraction pattern is 2.80 mm, what is the width of slit.
A horizontal pipe contains water at a pressure of 111 kPa flowing with a speed of 1.8.00 m/s. The pipe narrows to one-half its original diameter. What are speed and pressure of the water while the pipe narrows?
A device known as Atwood\'s machine consists of two masses hanging from the ends of a vertical rope that passes over a pulley. Assume the rope and pulley are massless and there is no friction in the pulley.
Far in space, where gravity is negligible, a 480-kg rocket travelling at 95 m/s fires its engines. The figure shows the thrust force as a function of time. The mass lost by the rocket all through these 30s is negligible.
determine the generating function for the transformation q=Q+Pt, p=P. Show that the hamiltonian H(p,q)=p^/2 + V(q) transforms to H'(P,Q)=V(Q+Pt)
