Answer:
The Sun's energy gets to the Earth through radiation, which you can prove just by standing outside and letting the sun's rays warm your face on a sunny day. Every object around you is continually radiating unless its temperature is at absolute zero, at which point its molecules completely stop moving.
Hope that helps :)

Could it be possible to run at the speed of sound with some future tool
Maybe in the future but now no. The fastest a human could run, according to most studies is about 36–40mph, and sound in dry air travels at about 760+ mph. That's considerably faster, almost 20 times actually. The reason why we couldn't ever run anywhere close to 760mph is because human muscles can't conract that fast.
Answer:
Scientists have discovered the fastest possible speed of sound. ... the absolute speed limit at which a wave can travel which is the speed of light

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

the formula is E = P x t
The battery doesn't 'use' power. The battery produces the power that all the other electrical devices use.
If the starter motor is using 2,520 watts, then the battery is producing energy at the rate of 2,520 watts. That means 2,520 Joules of energy every second.
Thanks for giving us the formula.
E = P x t
Energy = Power x Time
Energy = (2,520 watts) x (1 second)
Energy = 2,520 Joules
i really need help on this please help me
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.
the defense between an earthquake's focus and its epicenter.
Answer: The focus is the place inside Earth's crust where an earthquake originates. The point on the Earth's surface directly above the focus is the epicenter. The epicenter is the point on the surface above the focus, the place on the surface that would receive the most intense vibrations.

how does evaporation happen on a stove
(dont mind the subject btw)
*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆**☆*――*☆*――*☆*――*☆
Answer: Evaporation happens by heat being transferred to the pot, then the pot transfering the heat to the water, which caused the water to vibrate more, eventually turning it into water vapor, which is how evaporation happens on the stove.

Explanation:
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)

CHALLENGE
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!

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.

According to the Hertzsprung-Russell diagram, a star with a relatively low luminosity and a temperature of around 20,000 K is most likely which type of star?
A. Supergiant
B. Giant
C. White dwarf
D. Main sequence star
The correct option is C. White dwarf.
The following information should be considered:
Since the star having a low luminosity and a temperature of around 20,000 K.So based on this, the star change the fixture of the name of the planet also at the same time it measures the type of star that contains less luminosity star which we called as the white dwarf.Learn more: brainly.com/question/17429689

Why were the time zones established?
Answer:
The expansion of transport and communication during the 19th century created a need for a unified time-keeping system, and time zones were introduced. ... Before clocks were invented, people kept time using different instruments to observe the Sun's meridian passing at noon.

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.
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.

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.
