Answer:
the velocity of the car is 30 m/s.
Explanation:
Given;
Centripetal force on the car, F = 900 N
mass of the car, m = 10 kg
diameter of the circular path, d = 20 m
radius of the circular path, r = 10 m
The velocity of the car is calculated as follows;

Therefore, the velocity of the car is 30 m/s.
Answer:
A theory changes based on new observations and testing.
Explanation:
The first statement here refers to a law. A law states how something behaves without providing an explanation to such observations.
Scientific theories are explanation into a phenomenon. They give reasons to why certain patterns are noticeable.
They are based on multiple tests and validation of a hypothesis. By so doing, they can be changed based on new observations and testing.
Answer:
If you are at sea level, each square inch of your surface is subjected to a force of 14.6 pounds. The pressure increases about one atmosphere for every 10 meters of water depth. At a depth of 5,000 meters the pressure will be approximately 500 atmospheres or 500 times greater than the pressure at sea level.
