Chapter 28, Problem 38PQ

A lightbulb is connected to a variable power supply. As the potential across the bulb is varied, the resulting current and the filament’s temperature are measured. The data are listed in Table P28.38.

  1. a. Find R for each entry in Table P28.38, and then plot R as a function of T.
  2. b. Assume that room temperature is at 293 K. Find R0 (resistance at room temperature). Comment on your result.

How can i solve this if n1 (refractive index of gas) and n2 (refractive index of plastic) is not known. And the brewsters angle isn't known
2. Consider the situation described in problem 1 where light emerges horizontally from ground level. Take k = 0.0020 m' and no = 1.0001 and find at which horizontal distance, x, the ray reaches a height of y = 1.5 m.
2-3. Consider the situation of the reflection of a pulse at the interface of two string described in the previous problem. In addition to the net disturbances being equal at the junction, the slope of the net disturbances must also be equal at the junction at all times. Given that p1 = 4.0 g/m, H2 = 9.0 g/m and Aj = 0.50 cm find 2. A, (Answer: -0.10 cm) and 3. Ay. (Answer: 0.40 cm)please I need to show all work step by step problems 2 and 3
