Question
Chapter 7, Problem 1MCQ
To determine
The correct option corresponding to radian unit.
Expert Solution & Answer
Answer to Problem 1MCQ
Option (c)
Explanation of Solution
Write the equation for a radian.
Therefore, the radian is a ratio of arc length to the radius.
Conclusion:
The ration of degree/time will have unit different from the unit of radian given using equation (I). Therefore, option (a) is incorrect.
Length has a different unit compared that of arc length given in equation (I). Hence, option (b) is incorrect.
The unit of length\length will be same as that of radian given using equation (I). Hence, option (c) is correct.
The length\time has a unit different from the unit of radian given using equation (I). Therefore, option (d) is incorrect.

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.
A mirror hangs 1.67 m above the floor on a vertical wall. A ray of sunlight, reflected off the mirror, forms a spot on the floor 1.41 m from the wall. Later in the day, the spot has moved to a point 2.50 m from the
wall.
(a) What is the change in the angle of elevation of the Sun, between the two observations?
