The resistance R of a particular carbon resistor obeys the equation
√(log R'/T) = a + b log R',
Where a = -1.16 and b = 0.675.
(a) In a liquid helium cryostat, the resistance is found to be exactly 10000 (ohms). What is the temperature?
(b) Make a log-log graph of R against T in the resistance range from 1000 to 30,0000.
A 0.470-kg glider, attached to the end of an ideal spring with force constant k = 500 N/m, undergoes SHM with an amplitude 0.040 m. Compute the maximum speed of the glider. Compute the speed of the glider when it is at x = -0.015 m.
