As a new electrical engineer for the local power company, you are assigned the project of designing a generator of sinusoidal ac voltage with a maximum voltage of 120 {\rm v}. besides plenty of wire, you have two strong magnets that can produce a constant uniform magnetic field of 1.1{\rm t} over a square area with a length of 10.4{\rm cm} on a side when the magnets are separated by a distance of 11.6{\rm cm} . the basic design should consist of a square coil turning in the uniform magnetic field. to have an acceptable coil resistance, the coil can have at most 350 loops. what is the minimum rotation rate of the coil so it will produce the required voltage? express your answer using two significant figures.

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
