Question
Chapter 15, Problem 1VSC
To determine
The color that represents the brightest radio emission and the color that represents the lowest levels of brightness.
Expert Solution & Answer
Answer to Problem 1VSC
Solution:
The color that represents the brightest radio emission is white and the color that represents the lowest levels of brightness is black/dark blue.
Explanation of Solution
As the cold, dense molecular clouds are concentrated in a narrow layer near the midplane of the galactic disk, the white color in the middle represents the brightest radio emission.
As we see away from the midplane, there is less concentration of molecular clouds. So, the black/dark blue color represents the lowest levels of brightness.
Conclusion:
The color that represents the brightest radio emission is white and the color that represents the lowest levels of brightness is black/dark blue.

Part A:

(a) Water at 20 °C (p = 998.3 and v = 1 × 10-6 m²/s) flows through a galvanised
m³
iron pipe (k = 0.15 mm) with a diameter of 25 mm, entering the room at point A and
discharging at point C from the fully opened gate valve B at a volumetric flow rate of
0.003 m³/s. Determine the required pressure at A, considering all the losses that occur
in the system described in Figure Q1. Loss coefficients for pipe fittings have been
provided in Table 1.
[25 marks]
(b) Due to corrosion within the pipe, the average flow velocity at C is observed to be
V2 m/s after 10 years of operation whilst the pressure at A remains the same as
determined in (a). Determine the average annual rate of growth of k within the pipe.

For an independent study project, you design an experiment to measure the speed of light. You propose to bounce laser light off a mirror that is 53.5 km due east and have it detected by a light sensor that is 119 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor.
(a) Determine the angle that the normal to the mirror should make with respect to due west.(b) Since you can read your protractor only so accurately, the mirror is slightly misaligned and the actual angle between the normal to the mirror and due west exceeds the desired amount by 0.003°. Determine how far south you need to move the light sensor in order to detect the reflected laser light.
