A student is conducting an experiment to measure the rotational inertia of a bicycle wheel. The student measures the mass M And radius Of the wheel. The student wraps string around the wheel several times and then the free end of the string to the ceiling. The student releases the wheel from rest so that the wheel falls and rolls from the string. For each of the following parts, a full-credit response would state additional equipment the student would need, how the equipment would be used, what measurements are to be made, and what equations would be used and how they would be used. (a) Explain how the student can determine the linear acceleration of the center of the wheel as it falls toward the floor. (b) Explain how the student can determine the angular acceleration of the wheel. (c) Explain how the student can determine the tension in the string.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

Which form of cell division creates the sperm and egg, resulting in half of the chromosomes as the other cells?

Atennis player used a tennis racket to hit a tennis ball with a mass of 0.25 kg with a force of 5.25 newtons. how does the force the tennis racket exerted on the tennis ball compare with the force the tennis ball exerted on the tennis racket? a. the force of the tennis racket on the tennis ball is equal in magnitude and opposite in direction to the force the tennis ball exerted on the tennis racket. b. the force of the tennis racket on the tennis ball is equal in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. c. the force of the tennis racket on the tennis ball is less in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. d. the force of the tennis racket on the tennis ball is greater in magnitude and opposite in direction as the force the tennis ball exerted on the tennis racket.
