PLEASE ANSWER ASAP. Thank you. QUESTION: Explain the evidence that suggests that the universe is expanding.

Answers

Answer 1
One piece of evidence that proves that the universe is expanding is that there is a direct relationship between the speeds of distant galaxies and their distances from Earth. In fact, Hubble discovered that the farther away a galaxy is, the faster it is moving away from us. Although scientists today still don’t know the nature of this mysterious energy causing this acceleration, Hubble’s evidence has strengthened many theories about the large-scale structure of the universe.

what determines how far south the cold air from the north pole travels

Answers

Answer:

Please mark as Brainliest.

Explanation:

Polar easterlies are the cold and dry wind that blows from the polar regions (North pole and South pole) to the region of 60 degrees latitude. This type of wind is formed due to the sinking of the cold air resulting in the formation of a high pressure zone at both the poles. This wind when blows from the poles to the 60 degrees latitude, it slightly gets deviated towards the western side because of the effect of the Coriolis force. This Coriolis force comes into the picture due to the earth's continuous rotation.

Thus, the polar easterlies determines how far south the cold air travels from the North Pole.

plsss help​

Answers

Answer:

This refers to the condition, environment and or circumstance under which a speech or communication was made.

Explanation:

The context of a speech can significantly alter their meaning even though the body of the information has not changed. This is why understanding contexts are very crucial.

The context of a speech helps the receiver to make a decision about what to place importance on and about what, he or she can safely make assumptions about.

Some examples of communication contexts are:

Mass communicationIntrapersonal communicationInterpersonal communicationGroup communicationPublic communication

Cheers

Speech context has to do with the circumstances that are available which affects the meaning of a speech.

There are three types of speech context which include:

Intrapersonal InterpersonalPublic

As a result of this, when a person is making a speech to either himself, one more person, or to a group of people, it is important to note that the audience is very important so that the message will be well received.

Interpersonal communication has to do with the communication between people you have a close relationship with.

Intrapersonal communication is the type of communication where a person talks to himself, usually loudly.

Public communication is the communication among a group of people.

what are the steps for the respiratory system?

Answers

Answer:

Other components of the respiratory system conduct air to the lungs, such as the trachea (windpipe) which branches into smaller structures called bronchi. The process of breathing (respiration) is divided into two distinct phases, inspiration (inhalation) and expiration (exhalation).

Answer:

The primary organs of the respiratory system are the lungs, which function to take in oxygen and expel carbon dioxide as we breathe.The gas exchange process is performed by the lungs and respiratory system. Air, a mix of  oxygen and other gases, is inhaled.In the throat, the trachea, or windpipe, filters the air. The trachea branches into two bronchi, tubes that lead to the lungs.Once in the lungs, oxygen is moved into the bloodstream. Blood carries the oxygen through the body to where it is needed.Red blood cells collect carbon dioxide from the body’s cells and transports it back to the lungs.An exchange of oxygen and carbon dioxide takes place in the alveoli, small structures within the lungs. The carbon dioxide, a waste gas, is exhaled and the cycle begins again with the next breath.The diaphragm is a dome-shaped muscle below the lungs that controls breathing. The diaphragm flattens out and pulls forward, drawing air into the lungs for inhalation. During exhalation the diaphragm expands to force air out of the lungs. Adults normally take 12 to 20 breaths per minute. Strenuous exercise drives the breath rate up to an average of 45 breaths per minute.

Why are the tais pointing inward in layer H

Answers

Answer:

Because they are hydrophobic

Explanation:

The image shows a cell membrane, which is made up a phospholipid bilayer. The phospholipid bilayer is made up of a phosphate head, which is hydrophillic, and fatty acid tail, which is hydrophobic. That means they are repelled by water.

Because the tails are hydrophobic, they are repelled by the water towards one another, while the heads remain facing outwards,

How do oxbow lakes form? A. It is formed as lakes grow larger due to erosion and begins to look like an ox. B. It is formed when a bend in a river is cut off to form a lake. C. It is formed when a delta grows large enough to cut off a river to form a lake. D. It is formed when a dam stops the flow of a river and creates a lake.

Answers

Answer:

Oxbow lake is formed when a bend in a river is cut off to form a lake.

Explanation:

OPTON A - It is formed as lakes grow larger due to erosion and begins to look like an ox.

This statement is incorrect , as the shape of the oxbow lake is not like an ox , it is a horse-shoe shaped lake .

OPTION B - It is formed when a bend in a river is cut off to form a lake.

This statement is correct , as  An oxbow lake is a U-shaped lake that forms to create a free-standing body of water when a large meander of a river is cut off.

OPTION C - It is formed when a delta grows large enough to cut off a river to form a lake.

This statement is also wrong, as a river delta is specified by this statement.

OPTION D - It is formed when a dam stops the flow of a river and creates a lake.

This statement is also false, since the creation of a reservoir is established by this statement.

FORMATION OF OXBOW LAKE -:The neck of the meander gets narrower and narrower progressively. The curve gradually grows so close that the river slices through the neck of the meander to take a new, straighter path. Sediment locks the end of the old loop over time. This leaves a region of water that is different, called an oxbow lake.

Hence , the correct option is B.

Answers

Answer:

Explanation:

It would take 50 years to return to atmospheric CO2 levels from the year 1800. I know this because I set the fossil fuel usage to 0 and proceeded to simulate 50 years and that’s when the atmospheric CO2 levels returned to 600 GtC.

As per observation It could take 50 years to go back to atmospheric CO2 degrees from the yr 1800.

Each year, there has been no extrade in the quantity of CO2 withinside the ecosystem because of soil and land plants. coal also can be the answer.

Earth is 150 million kilometers from the sun, and the solar "wind" travels at about 400 km/sec. How long does it take particles from a solar storm to reach Earth? (Hint: Time = Distance / Speed. To convert from seconds to hours, divide the time in seconds by 3600.)

Answers

Answer:

The correct answer is - 4.34 days.

Explanation:

Given:

Distance from the sun to earth = 150 million kilometer

= 1500,00,000 km

The solar "wind" travels = 400 km/sec

= 400*60*60 km/ hour

= 1440000 km/hour

Then time = distance/speed

time = 1500,00,000 km/1440000 km/hour

time = 104.166666667 hours

time = 104.166666667/24

=  4.34 days.

Of the three waves shown, Wave 2 has the greatest
wave speed, because it has more crests than the other ropes
O frequency because it has a large wavelength than the other ropes
wave speed because the rope is moving up and down faster than the other ropes
frequency, because there are more crests in the same length of rope than there are in the other waves

Answers

Answer:

D. frequency, because there are more crests in the same length of rope than there are in the other waves

Explanation:

Wave frequency is defined as the number of waves passing a fixed point at a given time.

Wave frequency is highly influenced by the number of crests in the wave that pass the fixed point in 1 second. It means, more is the number of crests in the same length of rope, the higher will be the wave frequency.

Wave 2 has a maximum number of crests and thus wave 2 has the greatest wave frequency in comparison to other ropes.

Hence, the correct answer is "D".
