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
How does density play a part in convection currents? Explain.
(I NEED THE ANSWER ASAP)
Answer:
Convection is heat transfer due to a density differential within a fluid
Example:
The current begins when the air over the hot sand is heated and begins to rise because of its lowered density. Air from above the ocean is colder and more dense. This cooler air takes the place of the rising hot air from over the sand
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

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
Explanation:
A medium-sized star in the middle of its life cycle, such as the Sun, is most likely to emit which color of light?
A red
B blue
C white
D yellow
Answer:
D Yellow
Explanation:
You can tell by looking up to the sun. Or just by searching up a picture of our sun. Also, don't look up directly at the sun! It's very dangerous for your eyes.
Consider a car moving at a constant velocity. Recall that, for any object to move at a constant velocity, the net force acting on the object must be ________.
A. Fnet = 0
B. Fnet > 0
C. Fnet < 0
For any object to move at a constant velocity, the net force acting on the object must be ZERO.
QUESTION: What is the relationship between the masses of the objects and the gravitational force between them? (Another way of asking: What happens to the gravitational force as the masses get larger?)
helpppp due at 9:30am... n no mfkn links -_-
Answer:
As the masses get larger the force gets larger

Sound wave travels through water at 1,500 m/s. How far would it travel in 5 s?
Use the Speed of Sound Equation
s = d / t
As a parachutist falls with his parachute open, the downward force from the gravitational interaction is the same strength as the upward force of the drag interaction.
b. How would you describe the Forces? Explain whether or not the parachutist is accelerating.
no links pls pls plssssss :''(
Answer:
the forces are equal and the parachutist is not accelerating.
Explanation:
since the downward and upward forces are the same, the parachutist will not move up or down, so they are not accelerating.
i hope this helps! :D
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
The GALEX observatory was a recent observatory. that was launched to observe over a half-billion galaxies going back to when our Universe was just about 3 billion years old. It used wavelengths of higher energy than visible light. Which of these could describe the wavelengths used by the GALEX observatory to make observations in space?
A. microwaves
B. radio waves
C. Infrared waves
D. ultraviolet waves
Ultraviolet waves.
Hope this helps :)
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.
If the is the absense of light is the dark. thennnnnnnnnn since there is light particles. is there dark particles?if not then im dum

Which feature of the ocean floor is observed more than any other feature?
Which ocean floor feature is responsible for creating the largest mountain ranges in the world?
Which two ocean floor features are found most closely to the ocean shore?
Which ocean floor feature is responsible for creating new land? Which is responsible for destroying land?
Answer:
In fact, the tallest mountains and deepest canyons are found on the ocean floor; far taller and deeper than any landforms found on the continents.
Rising up from the abyssal plain, you would encounter the mid-ocean ridge, an underwater mountain range, over 40,000 miles long, rising to an average depth of 8,000 feet. Tracing their way around the global ocean, this system of underwater volcanoes forms the longest mountain range on Earth.
Underwater landforms · Continental shelf Abyssal plains Mid-ocean ridge Ocean trenches Plate tectonics and the ocean floor Hydrography.
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
At the deep-sea trenches, two plates converge, with one plate sliding down under the other into the mantle where it is melted. Thus, for each segment of new ocean floor created at the ridges, an equal amount of old oceanic crust is destroyed at the trenches, or so-called subduction zones.

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.
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.

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
Hope it helps...
