What guidelines are set forth by the USDA and MyPlate?
YOU WILL BE REPORTED IF YOU SUBMIT A LINK!
Answer:
The Dietary Guidelines for Americans (Dietary Guidelines) is the cornerstone for Federal nutrition programs and a go-to resource for health professionals nationwide. The Dietary Guidelines provides food-based recommendations to promote health, help prevent diet-related chronic diseases, and meet nutrient needs. As the MyPlate icon shows, the five food groups are Fruits, Vegetables, Grains, Protein Foods, and Dairy. The 2015-2020 Dietary Guidelines for Americans emphasizes the importance of an overall healthy eating pattern with all five groups as key building blocks, plus oils

Imagine that you are an auto designer. Your job is to design brakes for different automobiles. Write a four-sentence plan that explains what you need to consider about momentum when designing brakes for a heavy truck, a light truck, a small car, and a van.
Answer:
I won't write your sentences, but I'll give you some help on them.
Explanation:
For a heavy truck, I would use heavy brakes that have much more friction. That way they would be able to stop the trucks momentum.
A lighter truck I would use lighter brakes with less friction. If I had heavy ones and I need to slam on the brakes, they might damage my lighter truck.
A small car would need lighter and smaller brakes than either of the trucks, and I think that you use different brakes for cars and trucks. (not 100% sure)
In a van, I would use a size and weight in between the truck and car sizes and weight. Depending on the van size however, I might use the same ones.
Hope this helps!

In this image, there is a tractor, a left rope, a boy, a right rope, an elephant, and the ground. Identify at least six pairs of action-reaction force pairs in the following diagram.
Due By the 24th pls helpppp
When the tractor pulls, the boy moves. When the elephant moves, the boy moves. If the elephant moves and has more power than the tractor, the tractor and the boy moves. If the tractor moves and has more power than the elephant, then the elephant and the boy moves. I hope this helps you, have a great day!

Why do objects in the sky appear to move and change so much?
Answer:
It depends on the climate and wind speed at the time.
If the climate is hot and no breeze it will move slower.
If it is cold and very windy it will move rapidly.
If the Earth’s axis was TILTED MORE than it already is, what would happen to the seasons? *
Summer and winter would get more extreme.
The seasons would stay the same as they are now.
We’d still have summer and winter, but they’d be less extreme.
There would be no changing seasons. It’d be the same year-round.
Answer:
I'm not sure however I think it could be the first option
After you cross the finish line, you slow down and come to a stop, breathing hard. It takes you 10 seconds to come to a stop. What is your acceleration?
Acceleration = (change in speed) / (time for the change)
Acceleration = -- (speed as you crossed the finish line) / (10 seconds)

Team Kyoto and Team Copenhagen are engaged in a fierce game of Tug of War. Team Kyoto pulls to the left with a force of 5000N and Team Copenhagen pulls to the right with a force of 5000N. Explain what net force will be and in which way (if any) the rope will accelerate.
helpppp due in 20 mins no links pweysss
Answer:
net force will be 0N and the rope will not accelerate.
Explanation:
to calculate net force, you need to find the difference between the two forces, which would be 5000N - 5000N = 0N
since there is no net force, there is no movement of the rope.
i know it's been more than 20 minutes but i still hope this helps! :D
i really need help on this please help me
Which statement best describes why the Milky Way is shaped a certain way?
The gravitational forces from the center of the Milky Way cause stars and solar systems to orbit around the center of the galaxy.
The gravity from the sun causes all of the other stars and solar systems to orbit it.
The Big Bang caused the Milky Way to form into the supernova we see today.
The inertia of objects in space makes them travel far distances.

I’m giving points and an easy answer for y’all hope your having a great day ( and I think some people birthdays are in the 31 so if it is then happy birthday too! )
Choose the correct option.
If we hit a range, it will vibrate back and forth. The range pushes / pulls the air molecules next to it, causing them to move back and forth / straight, with the same frequency. These molecules push the layer of molecules down / near, so they also start to vibrate. In this way, the oscillation is followed by one molecule next to it.
Answer:
These molecules push the layer of molecules down / near, so they also start to vibrate. In this way, the oscillation is followed by one molecule next to it.

Is the gravitational force between the two objects attractive, repelling, or both? Explain how you know.
Answer:
Explanation: Gravity is always pulling any object to the center of the earth and we know that because if it not for gravity/gravitational pull we would be floating out of orbit and would not be to touch the ground.
The diagram below shows four forces acting on an object. The forces are labeled A, B, C, and D:
Describe the direction of the object’s motion based on the forces shown in the diagram. Be sure to include vertical (up and down) and horizontal (side to side) movement in your answer
no mfkn links pls pls plssssss
Answer:
the object will move in the direction of a and d, with a force of 10N acting on it.
Explanation:
the forces b and c cancel each other out because they are equal, but pushing the object in opposite directions. thus, 5N - 5N = 0N and the object does not move.
however, the forces a and d are moving in the same direction. 5N + 5N = 10N, which means that the object will move in the direction of both a and d with a combined force of 10N acting on it.
i hope this helps! :D
