(a) The car is undergoing an acceleration of
so that in 9.02 s, it will have covered a distance of
The car has tires with diameter <em>d</em> = 58.5 cm = 0.585 m, and hence circumference <em>π d</em> ≈ 1.84 m. Divide the distance traveled by the tire circumference to determine how many revolutions it makes:
(b) The wheels have average angular velocity
where is the average angular velocity, and are the initial and final angular velocities (rev/s), and are the initial and final angular displacements (rev), respectively, and is the duration of the time between initial and final measurements. The second equality holds because acceleration is constant.
The wheels start at rest, so
Answer:
dust cloud
Explanation:
Stars are formed from the accumulation of the dust as well gases in the solar system. The dust and the gases collapses due to the the gravity forces and the stars are formed.
They are formed within the clouds of the dust and gases and are scattered in the galaxies. The stars are formed in a million of years from the dust clouds.
In the context, Abdul have a picture of a dust cloud which looks smoky and dusty which is the initial stage of the stars formation due to the gravity. It is the region of the star that looks like a cloud of dust before the formation of the star.
Nicolaus Copernicus was the one who brought astronomy out of the dark ages.
In one of his books "On the Revolutions of the Heavenly Bodies", he published the renowned line which declares his theory.
Nicolaus Copernicus, A polish astronomer put forward the theory that the is th Sun one that rests in the middle or center of the Universe and the planet Earth revolves around it on its axis every day.which was considered to be called the Heliocentric system.
