(a)
Magnitude and direction of the force on each side of the coil in problem (24) for situation a), b) and c)

Answer to Problem 25QAP
Each side of b) situation have current of
In top side, force towards bottom
In bottom side, force towards top
In left side, force towards right
In right side, force towards left
In situation a) and b) there is no induced current, so there is no force
Explanation of Solution
Given info:
Formula used:
Calculation:
There is no induced current in a) and c) so there is no magnetic force in a) and c)
In b), there is an induced current, so the force on sides
Conclusion:
Each side of b) situation have current of
In top side, force towards bottom
In bottom side, force towards top
In left side, force towards right
In right side, force towards left
In situation a) and b) there is no induced current, so there is no force
(b)
Magnitude and direction of the force on each side of the coil when it enters from the left

Answer to Problem 25QAP
Each side of have current of
In top side, force towards bottom
In bottom side, force towards top
In left side, force towards right
In right side, force towards left
Explanation of Solution
Given info:
Formula used:
Calculation:
As the loop enters the field there will be an induced current in the loop
Conclusion:
Each side have current of
In top side, force towards bottom
In bottom side, force towards top
In left side, force towards right
In right side, force towards left

- Part A: kg (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. [15 marks] 4₁ Figure Q1. Pipe system Page 2 25 mmarrow_forwardFor 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.arrow_forwardA 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.
