The planet earth travels in a circular orbit at constant speed around the sun. what is the net work done on the earth by the gravitational attraction between it and the sun in one complete orbit? assume that the mass of the earth is given by me, the mass of the sun is given by ms, and the earth-sun distance is given by res.

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?
