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: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)
Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.
2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.
3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.
The things you said before about viscosity, density, and pressure are also correct. The correct answers are mainly talking about factors of the material being used in the pipes.

What would happen to the digestion process if enzymes were not present
Answer: It would take 2.3 billion years for the biological reaction without the presence of enzymes. It’s because, without them, your body can’t break down foods so that nutrients can be fully absorbed. Every organ, every tissue, and every 100 trillion cells in our body rely upon the reaction of metabolic enzymes and their energy component.

A meteor falls toward Earth's surface. Given that the acceleration due to
gravity is 9.8 m/s^2, what is the meteor's potential energy if it has a mass of 10
kg at an altitude of 400 m?
O A. 408 J
O B. 7,840,000 J
O C. 2J
O D. 39,200 J
Answer:
39,200J
Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J
correct option will be a) 39200 J

A yo-yo swung in a circle
When you drop something, first of all it accelerates.
The faster it falls, the bigger the force of ______ that acts on it.
choose from the list to complete the sentence:

note: apparently the answer is friction but it doesn't make sense to me so please explain.
The faster an object is going, the more resistance there will be. An example of this would be if you're running the faster you run, the more air is going against you.

Why is it possible for railway tracks to buckle even though there are gaps in them?
These gaps which are of the order of a few millimeters, are provided to allow room for the rails to expand the rise in temperature due to the atmospheric temperature as well as the friction caused by running of train. All materials expand when heated and contract when cooled. The extent of expansion and contraction is quite low to be noticed by people or make much difference in most situations. However, since each section of the rail is very long, the expansion due to heating is significant, and unless space is provided for expansion of rails, the rails will bend to accommodate the increased length. This will make the railway unfit for running of trains.
Answer: the tracks will buckle under the force.
Explanation: Heat-related expansion places a lot of stress on the ties, ballasts, and rail anchors that keep the tracks fixed to the ground.

Current will travel along the path with the highest resistance.
true or false
True. Being an electrical engineer, you learn very quickly that current will take All paths of resistance. But, the higher the resistance the lower the voltage. So, if a high resistance is shorted and the current flows through the short, there will be some small voltage across it, so some small amount of current will still flow through the high resistance.

Soil classification is partially determined by the presence of organic material, such as humus. Which would have more humus—a desert or a forest—and why? Check all that apply.
a forest because it has more trees to provide plant litter
a desert because it has soil with a larger particle size
a forest because it has more animals to mix the soil
a forest because the trees prevent rain from reaching the soil
a desert because the dry air decomposes plant litter
a desert because it has soil with a larger particle size. Hence option B is correct. Hence option B is correct.
What is Dessert ?Dessert is the final course of a meal. The dish includes sweet snacks like sweets and sometimes a beverage like dessert wine or liqueur. There is no tradition of a dessert course to finish a dinner in several regions of the world, such as Greece and West Africa, and in most parts of China.
Desserts include biscuits, cakes, cookies, custards, gelatins, ice creams, pastries, pies, puddings, macaroons, sweet soups, tarts, and fruit salad. Fruit is also typically seen in dessert courses due to its inherent sweetness. Desserts are made in certain cultures by sweetening savoury dishes. In the 18th and 19th centuries, when refined sugar and wheat were widely available and ostentation and artifice were desired, the dessert course achieved its pinnacle in the feasts of the European courts. Numerous creams, tarts, fruits, cakes, pastries, puddings, jellies, and meringues were given on tables decorated with flowers and architectural fancies made of sugar and pastry.
Hence option B is correct.

What is happening to the velocity of an object if it has a negative acceleration?
Answer:
According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.Explanation:
So it would be decreasing if its moving towards the negative!
3. Using the Kinetic Molecular Theory of Matter explain what is happening to the liquid in a thermometer when it measures something that is hot. What about when it measures something that is cold
According to the Kinetic Molecular Theory of Matter, the temperature of a substance is directly proportional to the average kinetic energy of the particles that make up the substance.
When a liquid thermometer measures something that is hot, the particles in the hot substance have a higher kinetic energy than the particles in the liquid thermometer. This causes the particles in the liquid thermometer to gain kinetic energy and move faster. As they move faster, they take up more space, causing the liquid to expand and rise in the thermometer.
On the other hand, when a liquid thermometer measures something that is cold, the particles in the cold substance have a lower kinetic energy than the particles in the liquid thermometer. This causes the particles in the liquid thermometer to lose kinetic energy and move slower. As they move slower, they take up less space, causing the liquid to contract and fall in the thermometer.
Therefore, when a liquid thermometer measures something that is hot, the liquid expands and rises in the thermometer, and when it measures something that is cold, the liquid contracts and falls in the thermometer.
