Calculate the work done by friction during one complete circular trip if the radius is (a) 2.00 m and (b) 4.00 m. (c) On the basis of the results you just obtained, would you say that friction is a conservative or non-conservative force? Explain.
A "friend" asks you to construct the phase diagram for a new binary alloy of A and B. The clues are: (i) A and B are completely immiscible in each other and no solid solutions exist in the diagram.
A supply of steam at 100 kPa, 150°C is needed in a hospital for cleaning purposes at a rate of 15 kg/s. A supply of steam at 150 kPa, 250°C is available from a boiler and tap water at 100 kPa, 15°C is also available.
A merry-go-round rotates from rest with an angular acceleration of 1.50 rad/sec^2. How long does it take to rotate through (a) the first 2.00 rev and (b) the next 2.00 rev?
