Biology

Yuri [45]3 years ago
5 0
The early atmosphere was probably mostly carbon dioxide, with little or no oxygen. There were smaller proportions of water vapour, ammonia and methane. As the Earth cooled down, most of the water vapour condensed and formed the oceans. ... For example, volcanoes release high quantities of carbon dioxide.

Two steel balls that are the same mass and size are rolled with the same force across different level surfaces.
san4es73 [151]

Answer:

The reason why the ball rolling across carpet will come to a stop faster than the one rolling across concrete is the friction (option B).

Explanation:

The contact surface on which the balls move is different. Irregularities in the carpet cause the ball in it to stop faster. The concrete surface is less irregular, and allows the ball to move a little more and then stop. This is due to friction.

In physics,<u> friction is a force that is capable of opposing movement</u>, since the contact of two surfaces limits its movement. A smooth surface produces less friction than a rough or irregular surface.

Since the friction that stops both balls occurs when they are in motion, it is called dynamic friction, that is, the force that causes a moving body to stop.
