A roller coaster containing four cars is accelerating at -15 m/s2 before it comes to an abrupt stop at the end of the ride. The mass of one car is 200 kg. How much force was exerted on the roller coaster to bring it to a stop
Answer:
F = -3000 N
Explanation:
Given that,
Mass of the car, m = 200 kg
A roller coaster containing four cars is accelerating at -15 m/s²
We need to find the force exerted on the roller coaster to bring it to a stop. Let F is the force.
F = ma
Putting all the values,
F = 200 kg × (-15 m/s²)
= -3000 N
So, the force us 3000 N and it act in opposite direction.
Hurricanes tend to disperse after making landfall because the land is much hotter than the ocean water.
Answer: False
Explanation:
For a Hurricane to keep going it needs to have hot air constantly going up and cold air coming down. When it gets to land, it loses access to the heat and moisture of the sea which is greater than on land. This forces it to weaken and to eventually dissipate.
Therefore, hurricanes disperse after making landfall because land is not as hot as the ocean water.

What are amphibians?
Any member of the group of vertebrate animals distinguished by their capacity to utilize both aquatic and terrestrial environments is referred to as an amphibian (class Amphibia). The word amphibian, which means "living a double life" in Greek, refers to this dual lifestyle, even though some species are entirely aquatic and others are permanent terrestrial residents.
There are now 8,100 different species of amphibians. They first appeared during the Middle Mississippian Epoch, around 340 million years ago. They were one of the first groups to depart from the ancestors of fish-tetrapods when animals evolved from purely aquatic forms to terrestrial ones.
Frogs and toads (order Anura), newts and salamanders (order Caudata), and caecilians are today's amphibians (order Gymnophiona). Despite having remarkably distinct body types, these three groups of contemporary amphibians—which are assumed to have descended from a single radiation of prehistoric amphibians—are most likely the closest relatives of one another.
Therefore, the survival of amphibians is dependent on land and water resources.

Explanation:
Which is not a part of the cell theory?
a. cells are the basic building block for living things.
b. all living things are made up of one or more cells.
c. animal cells are more advanced than plant cells.
Answer:
c
Explanation:
Answer:
The answer is C.
Explanation:
The cell theory has three parts; all living things are made of cells, cells are the basic units of life, and any cell comes from a pre-existing cell. So with these points, you can see that C is not a part of the cell theory.
Hope this helps :)
