Answer:
It was probably formed by when the particles were pressed together.
Explanation:
Answer:
200 km/h
Explanation:
Because the train is travelling 1000 km in 5 hours, you simply divide 1000 by 5, giving you 200 km/h. This is about 124.27 mph.
It’s going to be 35 bc it’s going the same way so it’s gonna be 35n
Answer:
the final angular velocity of the system would be 400 rpm
Explanation:
Recall that the kinetic energy of a rotating object is defined as:

where I is the object's moment of inertia, and
its angular velocity.
If the kinetic energy is conserved in the coupling of the two discs, then the final kinetic energy of the new system should be the same:

therefore the new angular velocity will be:

half of the initial angular velocity. That is :
the final angular velocity of the system would be 400 rpm
The answer is A. The Sun and all the planets revolve around Earth.
Aristotle believed that the Earth was the centre of the solar system, and the Sun and the planets orbited around it. He believed that the universe was composed of Earth-like bodies, which were at rest, and of heavenly bodies, which were in perpetual motion.
