Explanation:
Earth or any planet are actually born from huge clouds of gas and dust. Their stellar mass are fairly distributed at a radius from the axis of rotation. Gravitational force cause the cloud to come together. Now the whole gathered in smaller area. Now, individual particles come close to the roational axis. Thus, decreasing the moment of inertia of the planet.
As
I=mr^2
reducing r reduces I. However, the angular moment of the system remains always conserved. So, to conserve the angular momentum the angular velocity of the planet increases and so did the otational kinetic energy
Answer:
Scientific models have two basic types. FALSE.
Hoped I helped
If he runs at the same speed he will cover next 200m in 40s
that is at the average of 4.0m
What do you mean you need to be more specific
The answer for this would be B!!
