Explanation:
PE =200 J
m = 10
h=?
we know that ,
pE = mgh where g is acceleration due to gravity of earth = 10 m/s ^2
200= 10 ×10 × h
h = 2 m
and
KE = 1/2 mv^2
250 = 1/2 ×5 ×v^ 2
100 = V ^ 2
v= 10 m/s
Could somebody pls help me with this? thx

Please Help! What conclusions can you draw about how the amount of potential energy stored in system changes as a ball is placed at varying heights on a ramp? Write an evidence-based claim.
Answer:
The ball's potential energy in vertical circular motion depends upon the height of a ball concerning the referenced point at the bottom. Thus, the potential energy of the bowling ball moving in the vertical circular motion is maximum at the top concerning the bottom of the circular path.

why do you think you can see the effects on rocks after 200 years but not after 1 year?
Answer:
Yes, It is that We can see the effects of rocks after 200 year but not in 1 year. We cannot live 200 years but we can find the effect of rock from 200 years ago to today. Because , For seeing effect of rocks It needs process through natural agents. Water,Wind, etc. are some natural agents.
You just learned that phase changes do not always happen in an expected way. If you were a professional scientist studying this situation, how would you go about investigating this phase change? What other questions would you ask?
Answer:
What I would do to understand more is understanding different ways that phase change happens. I would ask questions like, how does phase change happen in ways unexpected or what are different ways that phase change can occur.
Explanation:
Just ask your self questions about things that contribute to phase change that you don't already now about the topic. Until you now everything you want to know. And also some ways to talk about how phase change can be unexpected is ways you would think a middle school kid would not expect a way how phase change can occur. Hope this helps!
Which one is the right spot because it really does not make any sense at all (in my viewpoint).

What could cause the weather to change suddenly like this: It was a calm and cloudy spring day in this Utah town. Suddenly the clouds grew dark and heavy, and a storm covered the town in a blanket of snow
Answer:
heres the answer: Daily changes in the weather are due to winds and storms. Seasonal changes are due to the Earth revolving around the sun, differences in temperature create a restless movement of air and water in great swirling currents to distribute heat energy from the Sun across the planet.

Why are rock samples from the Great Plains and from the Rocky Mountains composed of such similar minerals, when they look so different and come from different areas?
Answer:
The rock of the Great Plains is called sedimentary rock and the rock of the Rocky Mountains is called a igneous rock. A Sedimentary rock: is a type of rock that is formed by the buildup of mineral/organic particles at Earth's surface. And an Igneous rock: a type of rock that forms when magma (molten rock) cools/crystallizes. Since they formed in different ways they must not have formed together. Rocks can form in different ways, shapes sizes etc.. This causes them to be different types.
Explanation:
1) Sedimentary rock: type of rock that is formed by the accumulation or buildup of mineral or organic particles at Earth's surface.
2) Igneous rock: type of rock that forms when magma (molten rock) cools and crystallizes.
The North American Plate, on which both the Great Plains and the Rocky Mountains are situated, is a common tectonic plate.
What is rock?Rock is defined as a grouping of solid mineral grains that have grown or been cemented together. There are big rocks and little rocks. Rocks are created in the earth's crust. According to geology, rocks are produced when a combination of one or more minerals occurs. The sediments will eventually accumulate to such a high density that they will effectively turn into rock.
Although the Rocky Mountains' rock is volcanic and the Great Plains' rock is sedimentary, the two rock formations are stated to be different even though they contain comparable concentrations of specific minerals. Despite this, the two rocks have different formation processes.
Thus, the North American Plate, on which both the Great Plains and the Rocky Mountains are situated, is a common tectonic plate.

a. looking through a dark tunnel to see the light at the other end
b. looking at a bug through a microscope
c. looking toward the surface of a swimming pool from underwater
d. looking down in the ocean when you are snorkeling on the surface
The telescope is the device used for the enlargement of images of distant objects. The telescope image is analogous to looking at bugs under the microscope.
What is the similarity between telescope and microscope?
The microscope is the analytical device used to view the magnified image of the micro size organisms and matter.
The microscope and telescope both enlarge the image of the objects.
Thus, the view from the telescope is analogous to the bug view in the microscope. Thus, option B is correct.

A diver dives off of a raft - what happens to the diver? The raft? How does this relate to Newton's Third Law?
Action Force:
Reaction Force:
Answer:
Reaction Force!!
Explanation:
The diver moves “forward" and dives into the water. The raft moves "backwards” in the water because of the reaction force. The action force is the diver pushing off of the raft, and the reaction force is the raft pushing back on the diver (causing the diver to go forward and into the water).
