There are different kinds of statements. The statement that is true regarding the process-control relay ladder diagram shown in the figure (Image attached) is that;
- Only the temperature switch has to close for the motor to start.
Note that the pressure switch and the push button often occurs in stages or series and it is known to be parallel with the temperature switch.
The Relay Ladder Logic is known to be a primary programming language that is often used for programmable logic controllers (PLCs).
The ladder diagram often makes use of the contacts to show the switches, or any input. Note that the coil symbol often depicts the output. There is a line that is depicting an input/output and it is called a rung.
Pressure switches are said to be key parts that are used for managing or controlling the activation and deactivation of pumps in fluid systems.

Answer:
Part A
The intensity is
Part B
The intensity is
Explanation:
From the question we are told that
The intensity of the light detected by first eye is
Now at initial state according the question the light ray is perpendicular to the eye so it means that it is at 90° the eye
Now the first question is to obtain the intensity the first eye (the first in this case is the one focused on the light )would detect when the head is rotated by 20° its previous orientation
This is mathematically evaluated as
Now the second question is to obtain the intensity the first eye (the first eye in this case is the one that is not focused on the light )would detect when the head is rotated by 20° its previous orientation
Now in this case the angle between the eye and the light is 90-20 = 70°
So
