I think the answer is A B and E

Answer from: Muffinaubrey

The correct answers are B, C and E.

Explanation:

Centripetal force: It is the force which is required to keep the body in a circular motion. Otherwise, the body will follow straight line path. It makes the body to follow curved path.

The direction of the centripetal force is towards the center of the circle.

From the given options, the correct statements about the centripetal force are as follows;

Without centripetal force, an object would continue in straight line.

Friction can be centripetal force, such as when it keeps a car on road going around a curve. This force causes the car to turn in a circular path. It is due to friction between tires and road.

Gravity can be centripetal force, such as when it pulls a thrown baseball down to ground. For example, when the moon moves around the earth then the gravitational force is equal the centripetal force which keeps the moon moving in the circular path around the earth. Here, the centripetal force is gravity.

Therefore, the correct options are B, C and E.

Answer from: Quest

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by mathematical calculations before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of uranus led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
