A 3.0 kg cube on a spring (k=280 N/m) oscillates in simple harmonic motion. The cube has a speed of 0.55 m/s when it is 0.020 m from the equilibrium position.
(a) find the amplitude of motion.
(b) determine the cubes maximum velocity.
For a diverging lens (f = -22.0 cm), find the image distance for an object that is 22.0 cm from the lens. Determine the magnification of the lens
A current I flows in a semi-infinite straight wire along y = 2b, z = 0 from very large positive values of x to the point (0,2b,0), then around a semicircular wire centered upon (0,b,0) and in negative values of x in the z = 0 plane to the point (0,..
An energy-efficient lightbulb, taking in 24.0 W of power, can produce the same level of brightness as a conventional lightbulb operating at power 100 W. The lifetime of the energy-efficient bulb is 10 000 h and its purchase price is $4.20, whereas..
