Light of wavelength 560 nm illuminates a single 0.77 mm wide slit. At what distance from the slit should a screen be placed if the first minimum in the diffraction pattern is to be 2.47 mm from the central maximum?
What is the width of the central maximum?
A circular disk with the rectangular hole has a radius of 0.540 m and mass of 0.440 kg. It is suspended by a point on its perimeter. The moment of inertia about this point is I_p = 1.7×10-1 kgm2.
Determine the least value of n for which there is total internal reflection on the vertical surface.
A uniform bar is 5.00 m long and weighs 975 N. A weight of 255 N is attached to one end while a weight of 375 N is attached 1.50 m from the other end. Find the tension in the cable
What is the unknown charge at x = +0.19 m in micro-coulombs? If negative, indicate so with a negative sign, but omit a sign if positive.
Write down the original position of the system
Finally is the length is unchanged but the mass is equal to 0.500kg find the period T of the pendulum that is independent of the angle.
Does the change in speed of the downward-moving rock agree with the magnitude of the speed change of the rock moving upward between the same elevations? Explain physically why it does or does not agree.
A motorist drives south at 22 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.40 min, and finally travels northwest at 30 m/s for 1.00 min. For this 6.40 min trip, find out the following values.
A rod of length L is hinged at one end. The moment of inertia as the rod rotates around that hinge is ML2/3. Suppose a 2.00-m rod with a mass of 3.00 kg is hinged at one end and is held in a horizontal position. The rod is released as the free end is..
