A free body diagram shown above is for a 5kg box on a rough surface being pulled to the right at a constant speed by a string that is at an angle of 30 degrees above the horizontal. The coefficient of kinetic frictopn between the box surface id .30 the tendion on the string is most nearly

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?

Elements that have one valence electron and are very reactive are called

How are elastic and inelastic collisions different? give two or more ways. your answer should have at least 2 sentences.
