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.

The mass of April and her bumper car is 80 kg
Explanation:
This problem can be solved by using the law of conservation of momentum.
In fact, the total momentum of the system must be conserved before and after the collision, so we have:
where:
is the mass of Fiona+her bumper
is the initial velocity of Fiona (we take her direction as positive direction)
is the final velocity of Fiona (she rebounds back)
is the mass of April+her bumper
is the initial velocity of April (in the opposite direction)
is the final velocity of April
Re-arranging the equation, we can find the mass of April+bumper:
