Q. The temperature of the glass surface of a 60 W lightbulb is 67^circ C when the room temperature is 17^circ C. Estimate the temperature of a 160 W lightbulb with a glass bulb the same size. Consider only radiation, and assume that 90 % of the energy is emitted as heat.

Q. An oscillator with a mass of 420 g and a period of 0.900 s has an amplitude that decreases by 1.90% during each complete oscillation.
