A massless pan hangs from a spring that is suspended from the ceiling. When empty, the pan is 53cm below the ceiling. If a 100 g clay ball is placed gently on the pan, the pan hangs 74cm below the ceiling. Suppose the clay ball is dropped from the ceiling onto an empty pan.
What is the pan's distance from the ceiling when the spring reaches its maximum length?
The distance between the objective and eyepiece lenses in a microscope is 24cm, What eyepiece focal length will give the microscope an overall angular magnification of 350
A student makes a simple generator by using a single square loop 24 cm on each side. The loop is then rotated at a frequency of 60 Hz in a magnetic field of 0.044 T.
A disk with mass m = 8.5 kg and radius R = 0.35 m begins at rest and accelerates uniformly for t = 18.8 s, to a final angular speed of ? = 28 rad/s. What is the moment of inertia of the disk?
