The distance traveled by pendulum, in one back-and-forth swing is 75.75 inches.
The period of pendulum can be calculated by
Where,
- period
- length = 12 inches
- gravitational acceleration = 
Put the values,
Now, the angular displacement of the pendulum can be calculated by,
Where,
- amplitude
- angle = 
- angular displacement = 
= 2.866 m
Put the values and calculate for ,
Therefore, the distance traveled by pendulum, in one back-and-forth swing is 75.75 inches.

The order of the positive and negative feedback loops are positive, positive, negative, positive, positive, negative.
<h3>
What is a feedback loop?</h3>
A system component known as a feedback loop is one in which all or a portion of the output is used as input for subsequent actions. A minimum of four phases comprise each feedback loop. Input is produced in the initial phase. Input is recorded and stored in the subsequent stage. Input is examined in the third stage, and during the fourth, decisions are made using the knowledge from the examination.
Both negative and positive feedback loops are possible. Insofar as they stay within predetermined bounds, negative feedback loops are self-regulating and helpful for sustaining an ideal condition. One of the most well-known examples of a self-regulating negative feedback loop is an old-fashioned home thermostat that turns on or off a furnace using bang-bang control.

Answer:
None.
Explanation:
- By definition, work is a process that it happens when an applied force
causes an object to change its position, i.e. to have a displacement.
Since the laptop cart is at rest while he stops at the water fountain, no
net work done is on the laptop cart.
