Answer:
The loops are nested, and the program ends when loop 1 is completed. Since loop 4 is the innermost one, that one is completed first.
Answer:
The mechanical advantage is 0.25
This mechanical advantage shows that the force at which the deodorant sprays is the quarter of the applied effort, and hence the efficiency of your finger as a machine is 25%.
Explanation:
Given;
output force, F₂ = 15 N
input force, F₁ = 60 N
Mechanical advantage also known as force ratio is defined as the ratio of the output force (load) to the ratio of input force (effort).

This shows that the force at which the deodorant sprays is the quarter of the applied effort, and hence the efficiency of your finger as a machine is 25%.
Answer:
I think the answer is C and D
It might because of many reasons:
- Fan 1 is not connected to the Program (via Bluetooth, WIFI, or wired)
- The code made to make Fan 1 start up has a bug or an error
- Fan 1 has a hardware problem
- Fan 1 is out of reach for the electronically controller to reach
- Fan 1 is not connected to a power supply (tho)
