The nebular hypothesis explains how our solar system probably formed from a giant cloud of gases and dispersed solid particles.
<h3>What is Nebular hypothesis?</h3>
The most widely accepted theory in cosmogony to explain how the solar system formed and evolved is the nebular hypothesis. It implies that gas and dust orbiting the sun are what created the solar system.
Following are the steps in nebular theory:
- As part of the cloud of gas and dust condenses into a core and becomes a protostar, the nebula changes into a solar nebula.
- The material condensing might have been brought on by a nearby supernova shockwave.
- An accretion disk is formed as the protostar's surrounding material disintegrates.
<h3>How did the solar system form, according to the nebular hypothesis?</h3>
The nebular hypothesis states that enormous clouds of hydrogen and helium imploded. The cloud's center heated up significantly after collapsing. The system then started to rotate as it became hotter and more compressed. The formation of the solar system started at this point.

The light collected by a telescope is proportional to the area of the telescope.
The area of a telescope is π * (Diameter / 2) ^2 = π * (Diameter)^2 / 4.
So, for the 20.0 cm telescope, area = π * (20.0cm)^2 / 4.
And for the 5.0 cm telescope, area = π * (5.0 cm)^2 / 4
So, divide both expressions to find the ratio of collection of light of one telescope to the other:=> (20.0)^2 / (5.0)^2 = (20.0 / 5.0)^2 = 4^2 = 16
Then, the 20.0 cm telescope collects 16 times the ligth that the 5.0 cm telescope collect. <--- answer
Answer:
The done by the vertical component of force is zero.
Explanation:
Given data,
The mass of the textbook the women pushes horizontally, m = 3.2 kg
The displacement of the textbook, S = 3.5 m
Let the force of the women acts on the book horizontally,
Therefore, the horizontal component of force is maximum and the vertical component is zero.
If F is the force applied by the women, then the horizontal and vertical component of the force is,
Since the force is acting along with the horizontal x component, the vertical component of the force is zero.
Hence, the done by the vertical component of force is zero.
