The density of an isosceles right triangle (side lengths 1,1,√2) is the square ofthe distance to one of the 45◦vertices.(a) find its center of mass (choose an appropriate coordinate system and make a ) find its moment of inertia if the point of rotation is the vertex with the right angle.

What is a subatomic particle with a negative charge and very little mass?

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
