Answer:
- Driving surface area as subject to differential pressures
- How to achieve continuous rotation
- Mechanical connections
Explanation:
The general stages of thinking when designing a system are;
- First understanding the problem that requires you to design a solution
- Defining the problem that needs to be solved. In this case is to design an efficient hydraulic engine for a motorboat
- Research to find any available solutions for similar problems
- Idea of the solution
- A prototype to try solve the challenge
- Selecting and adjusting the prototype as you implement the solution.
For a hydraulic engine design, the following designing parts are vital;
- Driving surface area as subject to differential pressures
- How to achieve continuous rotation
- Mechanical connection
Pressures are important due to motor displacements. Fuel burns in the cylinder to cause power through fuel gases burning and expansion which is the four-stroke cycle. Continuous rotation will come in the design considerations through reciprocating motions of pistons into rotary motions. Mechanical connections are vital especially in crank shaft turns, gear box that turns horizontal motions to spinning motions and finally the propeller that drives the boat on the water.
I think the answer is B) 1 a.m. and 5 a.m. I very sorry if it is wrong plz let me know if it is wrong bro thankx
Answer:
b) socialism
Explanation:
Conflict theory focuses on the competition between groups within society over limited resources. Conflict theory views social and economic institutions as tools of the struggle between groups or classes, used to maintain inequality and the dominance of the ruling class.

Explanation:
The equivalent of the resistance connected in the series will be Req=R₁+R₂+R₃.
<h3>
What is resistance?</h3>
Resistance is the obstruction offered whenever the current is flowing through the circuit.
So the equivalent resistance is when three resistances are connected in series. When the resistances are connected in series then the voltage is different and the current remain same in each resistance.
V eq = V₁ + V₂ + V₃
IReq = IR₁ + IR₂ + IR₃
Req = R₁ + R₂ + R₃
Therefore the equivalent of the resistance connected in the series will be Req=R₁+R₂+R₃.
