Q. Two physical pendulums ( not simple pendulum) are made from sticks that are suspended from the ceiling at one end. The sticks are uniform and are identical in all respects, except that one is made of wood (mass = 0.17 kg )and the other of metal (mass = 0.85kg ) . They are set into oscillation and execute simple harmonic motion. Determine the period of (a) the wood pendulum and (b) the metal pendulum
the center of a 1.50 diameter spherical pocket of oil is 1.00 beneath the Earth's surface.Estimate by what percentage directly above the pocket of oil would differ from the expected value of for a uniform Earth?suppose the density of oil is 8.10^2 ..
A pair of speakers separated by 0.820 m are driven by the same oscillator at a frequency of 652 Hz. An observer originally positioned at one of the speakers begins to walk along a line vertical to the line joining the speakers.
An electron librated from a hot filament cathode is attracted by an anode with a potential of 1200V positive with respect to the filament. Compute the speed of the electron when it strikes anode.
Calculate change in kinetic energy
A uniform plank of length 5.8m and weight 229N rests horizontally on two supports, with 1.10 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs 450N walk on the overhanging part of the plank be..
An automobile club plans to race a 780 kg car at the local racetrack. The car needs to be able to travel around several 170 m radius curves at 85 km/h. What must the banking angle of the curves be so that the force of the pavement on the tires of the..
A 1500 kg car traveling at a speed of 20 m/s skids to a halt on wet concrete where kinetic friction= 0.20. How far are the skid marks.
A pendulum of length 1.5 m is held out to point A. At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 1.09 m. (That is, 1.0 m is no longer free to swing.) How long does this pendulum take for one o..
A space station, in the form of a wheel 133 m in diameter, rotates to provide an "artificial gravity" of 2.20 m/s2 for persons who walk around on the inner wall of the outer rim. Find the rate of the wheel's rotation in revolutions per minute that wi..
Two point charges, +3.09 µC and -6.05 µC, are separated by 1.33 m. What is the electric potential midway between them?
A hockey stick is swung with the average angular acceleration of 1.5 rad/s2. What is the angular velocity of the stick as it strikes the ball at the end of 0.8 second swing.
Two small insulating spheres with radius 4.00×10-2 are separated by a large center-to-center distance of 0.595. One sphere is negatively charged, with net charge -2.40, and the other sphere is positively charged, with net charge 3.70. The charge i..
