<u>Answer:
</u>
Gravity causes stars to form out of gas clouds
.
<u>Explanation:</u>
The formation occurs in molecular clouds in the interstellar space. The atoms of light are first forced under sufficient pressure so that their nuclei undergo fusion. The gravitational force is responsible for this fusion to begin.
The gases present in these clouds clump to form molecules with higher densities. Due to the internal gravitational disturbance, there begins to occur a collapse of the denser regions of the cloud. As the collapse continues to occur, the temperatures begin to increase and each of the smaller clouds will eventually form a star.

<u>Answer:</u>
The given scenario is an example of a batch process.
<u>Explanation:</u>
- A batch process is a non-user interactive process where a batch of product or database are processed in a batch.
- Although batch processing is generally costly to design and implement, this can be used as a effective tool to save money and labor overtime.
- Usually, batch processing is used in a periodic basis but it can be used when needed at any time. Batch processing is greatly used at end of the period.
- One of the drawbacks of batch processing is that the individual data input should not be incorrect because it may affect, the result of overall batch which will eventually lead to loss if time and spend of more money.
