yoyo is operated in space, so that there are no other forces acting on it but the tension in the string. The yoyo has a mass of .150 kg and a moment of inertia of 1.00E-4 kg·m2. A string is wrapped around the inner radius the yoyo which has an outer radius of 4.00 cm and an inner radius of 1.50 cm. If a constant tension of 0.600 N is applied to the string, determine (A) The acceleration of the yo-yo’s center of mass, (B) The angular acceleration of the yo-yo about its center of mass.​

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.
