what do you think a divergent (constructive) boundary is? How do plates interact with each other?


Answers

Divergent boundaries usually occur when two tectonic plates or more pull away from each-other causing the empty spaces to fill with magma or water. Tectonic plates interact with each-other in many different ways, they can move towards one another (converge), or move away from one another (diverge), or slide past one another (transform)... These movements occur during earthquakes.

I do not understand Net Force at all- I would really appreciate it! I'll also include a brainliest since it is quite a bit! Thank you!

Answers

Answer:

See below

Explanation:

Net Force is the force which is the sum of all the forces acting on object i.e. pushing of pulling.

Net Force:

1)   4N (net force is 4N to the left)

2)  2 - 7 = -5N (net force is 5N to the left)

3)  4 - 4 = 0  (net force Zero)

4)  6 + 3 = 9N (net force is 9N to the right)

5)  4 - 8 = -4N (net force is 4N to the left)

6)  4 - 5 = -1N (net force is 1N to the left)

7)  -3 - 3 = -6N (net force is 6N to the left)

8)  2 + 4 - 5 = 1N (net force is 1N to the right)

9)  3 - 6 = -3N (net force is 3N to the left)

10.  4 + 4 - 7 - 1N (net force is 1N to the right)

Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys. These are also known as constructive boundaries. ... This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction.

When sound waves cause the eardrum to vibrate, these vibrations are immediately passed on to the _______________.


outer ear and ear canal


tiny hairs


three small bones in the middle ear


inner ear

Answers

Answer: three small bones in the middle ear

Explanation: Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

When sound waves cause the eardrum to vibrate, these vibrations are immediately passed on to the three small bones in the middle ear. So, the correct option is C.

What are Sound waves?

A sound wave is defined as a pattern of disturbance that is caused by the movement of energy that travels through a medium such as air, water or any other liquid or solid substance as it propagates away from the source of the sound which is the object made by vibration and pressure generate waves, for example, a ringing cellphone.

These waves enter the outer ear and pass through a narrow passage called the ear canal leading to the eardrum which vibrates with the incoming sound waves and sends these vibrations to three small bones in the middle ear where these bones are called malleus, incus. and steppes.

Thus, the correct option is C.

what was Galileo's contribution to the study of motion​

Answers

Answer:

The law of falling bodies is one of Galileo's key contributions to physics. It states that objects fall at the same speed regardless of weight or shape. Through his experiments, Galileo countered the pervasive Aristotelian view, which held that heavier objects fall faster than lighter objects.

Explanation:

Answer:

Galileo’s contribution to the study of motion is that he was the first to systematically study force and motion.

Explanation:

Galileo Galilei was the first person to scientifically invest himself in producing answers about force and motion.Galileo was first built up the idea of inertia the possibility that an article stays in rest or moving until followed up on by another power which turned into the reason for one of Isaac Newton's laws of motion.The law of falling bodies is one of Galileo's key commitments to material science.It expresses that articles fall at a similar speed paying little heed to weight or shape.Through his tests, Galileo countered the unavoidable Aristotelian view, which held that heavier items fall quicker than lighter objects

In 3-5 complete sentences, compare those three ways that waves change direction.

Answers

Reflection is a change in direction of a wave between two different objects that is the Wave returns to the medium from which it begins.
Refraction is When a light travels from air into water it slows down causing it to change direction slightly.

Diffraction Involves a change in direction of waves as they pass-through and opening.
Reflection is a change in direction of a wave between 2 different objects that is the wave returns to the medium from which it begins.
Refraction is when a light travels from air into the water it slows down causing it to change direction slightly.

Do you think his evidence is strong? Why or why not?

Answers

Answer:

No

Explanation:

The reason why Barry's evidence isn't strong because "it's not enough to support his claim" that strong magnets repel and weak magnets attract. Barry needs to have at least three trials for each test to greater prove his claim. Doing so will show that the test isn't incorrect because he repeated the test multiple times and got the same results. If Barry does three trials for each test and record his results then he would have enough evidence to support his claim.

Hope this helps.

No, the evidence is not strong enough, as there is a lack of repetition and information on how the experiment was done.

What is missing?

The first thing that is missing is information on how the experiment was done, things like

How strong is the strong magnet?How strong is the weak magnet?Which pole is which on each magnet?

Strong and weak magnets behave in the same way, opposite poles attract and equal poles are repelled, thus, there must be a problem with Barry's experiment.

Ignoring that, another problem is the lack of repetitions. An experiment must be done several times to see if the results are always the same, in the given evidence it was done only once for each, so we don't know if after another trial the outcomes will be the same.
