A25.0-kg child is standing at the edge of a horizontal merry-go-round with a radius of 2.40 m and a moment of inertia of 356 kg∙m2 about a vertical axis through its center. the system (including the child) is initially rotating at 1.80 rad/s.
what is its angular velocity if the child moves to a new position 1.20 m from the center of the merry-go-round?

Decreased sensitivity to an unchanging stimulus is known as

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?

Energy transformations that involve one transformation from one type of energy to another are called transformations.
