A glob of very soft clay is dropped from above onto a digital scale. The clay sticks to the scale on impact. The experiment is then repeated, but instead of using the clay glob, a superball with identical mass is dropped from the same height onto the scale. Both the clay and the superball hit the scale 2.9s after they are dropped. Assume that the duration of the collision is the same in both cases and the force exerted by the scale on the clay and the force exerted by the scale on the superball are constant.

Required:
a. Sketch the graph of the superball's velocity vs. time, vball , from the instant it is dropped (t=0sec) until it bounces to its maximum height (t=6sec). Assume that the superball undergoes an elastic collision with the scale, and that the scale's recoil velocity is negligible. The light colored graph already present in the answer window is vclay (t).
b. Based on your graph, is the change in velocity of the superball during its collision with the scale greater than, less than, or equal to the change in velocity of the clay during its collision with the scale?
c. Is the force exerted by the scale on the superball greater than, less than, or equal to the force exerted by the scale on the clay?

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.

7.45 a student is interested in the aerodynamic drag on spheres. she conducts a series of wind tunnel tests on a 10-cm-diameter sphere. the air in the wind tunnel is at 50 â°c and 101.3 kpa. she presents the results of her tests in the form of a correlation, đť’ź = 0.0015v1.92, where đť’ź is the drag force in newtons and v is the velocity in m/s. another student realizes that the results would have been more effectively presented in terms of dimensionless parameters, say, î 1 = f (î 2) = c î a2 , where î 1 and î 2 are dimensionless parameters and c and a are constants. what are the most appropriate dimensionless parameters (î 1 and î 2) and the corresponding values of c and a? what would be the drag on a 2-cm-diameter sphere placed in a 1-m/s, 20 â°c water stream?
