A spherical shell with inner radius r1 and outer radius r2 has surface temperatures T1 and T2, respectively, where T1 T2. Sketch the temperature distribution on T r coordinates assuming steady-state, one-dimensional conduction with constant properties. Briefly justify the shape of your curve?

Which of the following best describes the circuit shown below?

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.

Which statement is true about an object that is moving in a circular motion due to centripetal force, f, when the radius of its circular motion is doubled? the new force then becomes equal to 2f the new force then becomes equal to f the new force then becomes equal to f/2 the new force then becomes equal to f2 the new force then becomes equal to 1/f
