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.

Coral reefs form when the calcite skeletons of coral build upon each other.
deff fn [24]
It is TRUE that coral reefs form when a<span> structure of calcite skeletons built up by coral animals in warm, shallow ocean water. </span>To form their skeletons, coral animals absorb the element calcium from the ocean water. The calcium is then combined with carbon and oxygen to form calcite (calcite is a mineral). When coral animals die, their skeletons remain. More corals build on top of them, gradually forming a coral reef.
