A wheel of radius 74 cm, mass 4 kg, and moment of inertia 1.0952 kg m2 are mounted on a frictionless, horizontal axle as shown. A light cord wrapped around the wheel supports an object of mass of 1.7 kg. Find the tension T in the cord. The acceleration due to gravity is 9.8 m/s^2 Answer in units of N.

What is the angular acceleration of the wheel?
Answer in units of rad/s^2

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
