Answers
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

Waldo gets stopped by the police, and the police officer tells Waldo that she caught him on radar doing 50 miles per hour in a 40 miles per hour zone.
Waldo responds, " I was traveling 50 miles per hour. I sat at home for 1 hour and then drove for 1 hour before you stopped me. I traveled 50 miles total in that second hour. So, my speed was 25 miles per hour. That's well under the speed limit."
Waldo is wrong, per speeding laws, and does receive a speeding ticket. Explain how Waldo came up with a speed of 25 miles per hour in multiple sentences.
Answers
Answer:
He calculated his average speed.
Explanation:
Waldo calculated an average of his speed in 2 hours rather than his speed whilst driving which means instead of doing 50/1 hour = 50 mph, he did 50/2hours which is how he got 25 mph. 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
Answers
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.

You have learned that power is the speed, or rate of doing work. In this report you will learn more about James Watt or horsepower.
Here is your goal for this assignment:
Complete an activity on power
Complete one of these activities:
1. Research the life of James Watt. Report in about fifty words some of the important events in Watt's life leading up to the watt being named in his honor.
2. Conduct a survey of equipment and cars to find out the amount of horsepower of each item you check. You may visit a car dealer, an appliance store, a heavy-equipment dealer. Make a list of the horsepower of at least ten items of equipment. Some suggestions include: comparing two or three different makes of cars or finding the horsepower of a lawn mower, boat, vacuum cleaner, or some heavy equipment for moving dirt. You may find that the power of a washing machine or vacuum cleaner is given in watts instead of horsepower. Make a chart to record your findings, including:
Type of Equipment Surveyed: (Indicate whether it is a car, shovel, vacuum cleaner, etc.)
Amount of Horsepower or Watts: (Record power in horsepower or in watts.)

(i did number 1) James Watt was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine. In 1762, he began studying steam engines. With his knowledge, in 1763, he repaired a "Newcomen" engine owned by the university. However, while repairing it, he was impressed by its waste of steam, and came upon a solution, the separate condenser. It was his first invention, and he created it in 1769. In 1765, he produced his first working model of the 'Watt' engine (with separate chambers for piston and steam). (i rly hope this helps no need to mark branliest if it doesnt)

Where do the animals you read about get the energy storage molecules they need to do the activities required for reproduction?
Answers
The animals that you read about get the energy storage molecules they need for reproduction from the food they eat. Food provides the energy and nutrients required for various biological processes, including reproduction.
What is reproduction?Reproduction is the biological process by which organisms produce offspring, either sexually or asexually, to ensure the survival and continuation of their species. It is an essential characteristic of living organisms and is critical for the maintenance of genetic diversity within a population.
Sexual reproduction involves the fusion of gametes (reproductive cells) from two parents, which results in the formation of a new individual with a unique combination of genetic material. In most sexual reproduction processes, the male produces sperm, while the female produces eggs. The sperm and egg unite during fertilization, which creates a zygote that develops into a new organism.
Asexual reproduction, on the other hand, involves the production of offspring from a single parent without the fusion of gametes. The offspring produced through asexual reproduction are genetically identical to the parent, except for mutations that may occur during the process.
Reproduction is essential for the continuation of a species and is responsible for maintaining the genetic diversity within a population. It also plays a critical role in the evolution of species by allowing for the accumulation of genetic variation through sexual reproduction and mutation.
Here in the Question,
The three main macronutrients in food that provide energy for the body are carbohydrates, proteins, and fats.
These macronutrients are broken down during digestion into smaller molecules such as glucose, amino acids, and fatty acids, which can be used by the body to produce energy through cellular respiration.
The energy produced from food is stored in the form of adenosine triphosphate (ATP), a molecule that provides energy for various cellular processes, including reproduction. Animals obtain their energy storage molecules such as ATP through the process of cellular respiration, which occurs in the mitochondria of cells.
Therefore, animals get the energy storage molecules they need for reproduction from the food they eat, which provides the necessary nutrients and energy required for various biological processes.

Answer: It's kind of a subjective question by saying Which of the following pictures should be placed on the side of heat being removed from the material?
Explanation: I'm not entirely sure about this but I would think that it would be baked cupcakes because they had to undergo heat to become "baked", so they are the result of heat.

Samantha is investigating the densities of several liquids. Which action is the result of her creative thinking.
Answers
Answer: B
Explanation: because it just is
We can use standard data of densities of liquids to investigate them otherwise we can conduct small experiments with comparing the densities of commonly available liquids used in foods.
What is density?Density is the measure of the mass per volume. Mathematically it is written as the ratio mass/volume. This physical quantity provide insights to determine how denser it is and thus the flow of the liquid also.
Different liquids have different densities. Water has a density of 1 g/L at normal temperature and it is maximum at 4⁰C. Therefore, density of a liquid depends on the temperature, pressure and the bond type also.
We can compare the densities of common liquids that are available in our home such as honey, oil, kerosene, petrol, milk, curd etc.
Each have different densities based on their mass and volume taken. To determine the density, we can first take a known mass of the liquid to a container of known volume and thus density can be calculated.
The calculated densities can then be compared with the standard values available in record. Thus both option B and D are correct.
