The correct answer is C. A PFD takes some time to fit properly especially in an emergency.
Explanation:
The purpose of a Personal Flotation Device (PFD) such as a life jacket is to keep people floating to prevent drowning. Additionally, its effectiveness depends on whether the Personal Floating Device was fitted properly. Because of this, if an activity involves being in or around water, it is important to wear a Personal Flotation Device and to fit this properly before approaching the water because it is difficult to adjust the device during an emergency. Thus, it is important to wear a PFD in or around water because this takes some time to fit properly (Option C.)
It is important to always put on a personal flotation device (PFD) when in or around water because a PFD takes some time to fit properly, especially in an emergency.
What is a personal flotation device?A personal flotation device is a device required to be worn by anyone near a water body to protect the individual in case of emergency when in or around the water.
It is worn as a life jacket and it requires air to fill it. However, this makes takes time to fill and fit properly, that is why it is crucial to always put on a PFD when in or around water because of emergency situations.

All the ideas are noted down without criticism and after the brainstorming session the ideas are evaluated.
Opinion: Choose a side and defend it in four to five sentences. Given the choice between a vehicle that runs on gasoline or one that runs on electricity such as the Aptera 2e, which would you choose and why? Think about fuel consumption, design of the vehicles, and other factors that may influence your decision.
Answer:
my opinion would be electric
Explanation:
because when it comes down to the bare minimum the best choice for the world in the long run would be electric because it puts a big dent back for global warming and the burning of gasses so the more people who drive electric cars are the people who are trying to save the world a little at a time by preventing the burning of gasses. hope this helps :)

Describe 3 factors an engineer should take into consideration when choosing material for building the pipes in a pipeline
Gr. 8
Think it has something to do with Viscosity, Density, and Pressure but not sure what
Answer:
Durability: The material used for building pipes in a pipeline should be able to withstand the conditions it will be exposed to, such as pressure, temperature changes, and corrosion.Flow properties: The viscosity and density of the liquid or gas that will be flowing through the pipeline should be taken into consideration when choosing the material for the pipes. Materials with lower viscosity and density will be more suitable for transporting fluids with high flow rates.Cost: The cost of the material used for building pipes in a pipeline is an important consideration. Engineers need to choose a material that is both durable and cost-effective, while still being able to meet the flow and pressure requirements.Answer:
design, material, cost

Problem 4-2. A steam power plant operates on
an ideal reheat-regenerative Rankine cycle as
shown. Steam at a rate of 75 kg/s enters the high
pressure turbine at 10 MPa and 560°C and leaves
at 0.7 MPa. A fraction of the steam is extracted at
this pressure to heat the feedwater in a closed
feedwater heater. The rest of the steam is reheated
to 500°C and then it is expanded in the low-
pressure turbine to the condenser pressure of 10
kPa. It is assumed that the feedwater leaves the
closed feedwater heater (State 8) at the
condensation temperature of the extracted steam.
a: show the T-a diagram for the cycle, then calculate
B: the net power output
C: The thermal efficiency of the cycle

The best definition of synthesizing information is "You must use the most important information from several sources to create something new". Thus, option C is correct.
What are the protein digestion's intermediary byproducts?Amino acids can be used as a source of energy generation thru the Krebs cycle since digesting them yields metabolic intermediates such pyruvate, acetate CoA, acetoacyl CoA, decarboxylation, or -ketoglutarate.
Acetyl-CoA is a crucial intermediate involved in numerous metabolic pathways, such as cellular respiration, the metabolism of fatty acids, steroids, and amino acids, the synthesis of ketone bodies, and the production of neurotransmitters. It has also been suggested that acetyl-CoA may have an impact on the AMPK signalling pathway.
Therefore, The best definition of synthesizing information is "You must use the most important information from several sources to create something new". Thus, option C is correct.

Explain how a CO2 cartridge powers the dragster you will be building. A good website to use is How Stuff Works. (howstuffworks.com) Write a good paragraph or two to explain your answer in complete sentences.
Answer
C02 cartridges are compressed.
Explanation:
The C02 Cartridge will be used to power our dragsters by the compression inside of the bottle. Since C02 is a compressed gas inside of a small container, The pressure when released my provide enough force to move the dragster at high speeds. An example of this would be like an air soft gun. some air soft guns are used by small C02 Cartridges, which let out a strong burst of compressed C02, which fires the projectiles at very high speeds.

Securely glue or tape the piece of cardboard onto the box.
Make lengthwise guides to keep the ball on the ramp. Connect three straws end to end. To connect them, squeeze the end of one straw and insert it into the end of another straw. Tape the guide along one side of the ramp. Make a second guide using three more straws. Tape it along the other side of the ramp. The space between the guides should be a little wider than the width of the ball.
Set up the ramp. The top of the ramp should be 12 inches off the floor. Place the box (vehicle 1) at the base of the ramp—the box should be touching the end of the ramp. The side with the added cardboard piece should face the ramp. Orient the box so it’s wider than it is high.
Let the ball roll down the ramp and hit the box. The box should fall over and move across the floor.
The amount of force in this collision can be measured indirectly. Simply measure the distance the box moved after the ball hit it. What procedure can you use to measure the distance?
Answer: Inches
Explanation:
Securely glue or tape the piece of cardboard onto the box. Make lengthwise guides to keep the ball on the ramp. Inches
What is force in collision?Collisions between two objects naturally fall under Newton's third law of motion. When two objects collide, forces of equal magnitude and opposite direction are applied to each object.
Such pressures frequently result in one thing gaining momentum and gaining speed while the other object slows down (lose momentum). Newton's third law states that the forces acting on the two objects are of equal strength.
The objects' accelerations may not be equal in magnitude even though the forces acting on them are opposite in direction and of equal magnitude.
Therefore, Securely glue or tape the piece of cardboard onto the box. Make lengthwise guides to keep the ball on the ramp. Inches.
