In the nebular hypothesis, why did the nebula start to collapse?

Chemistry
1 answer:
ryzh [129]2 years ago
8 0

1.Four major features provide clues:

(1) The Sun, planets, and large moons generally rotate and orbit in a very organized way.

(2) With the exception of Pluto, the planets divide clearly into two groups: terrestrial and jovian.

(3) The solar system contains huge numbers of asteroids and comets.

(4) There are some notable exceptions to these general patterns.

2. Gravity causes the early solar nebula to collapse. The solar nebula flattens and warms at its core as it revolves. Within the spinning disk, planetesimals (early planets) begin to form.

3. Because the center of the revolving disk had the least amount of centripetal force, the majority of the mass from the nebula cloud was drawn to it by gravity. The majority of the material was hydrogen gas that was subjected to extreme pressure, which heated it to a critical point, causing it to fuse with another hydrogen atom, resulting in the formation of helium and the birth of the sun.

4. Nebular Theory: argues that when the Sun formed in the nebula, it created planets, asteroids, and other bodies from a spinning disk of materials known as the accretion disk. Almost all revolve in the same direction on their axes. Venus and Uranus are moving backwards on their axes.

5. In the inner solar nebula, only dense materials could condense. The Jovian planets are really denser than the terrestrial planets. Gravity compresses terrestrial planets to a greater extent, causing them to become denser. The gravity of the Sun drew dense materials into the inner solar system.

A pharmaceutical company wants to test the efficiency of its new drug production techniques so they run 3 shifts of production f
spayn [35]

The percentage yield of the  new production technique is 82.8%

<h3>What is the percentage yield?</h3>

Production is the procedure by which finished products are obtained form the raw materials. The production process involves the passing of raw materials through a certain procedure that involves the use of certain machines and equipment to give us the required products.

We are told in the question that there are three shifts;

Shift 1 produces 4562 grams

Shift 2 produces 5783 grams

Shift 3 produces 5247 grams

Average production from the three shifts = 4562 grams + 5783 grams +  5247 grams/3 = 5197 grams

The theoretical average yield is =  7000 grams + 7000 grams + 7000 grams/3 = 7000 grams

Now the percentage yield = actual yield/ theoretical yield * 100/1

percentage yield = 5197 grams/7000 grams * 100/1

percentage yield = 82.8%
