What’s a star? In complete sentences.

Physics
1 answer:
Alexxx [7]3 years ago
5 0
Hello!

A star is a large, spherical burning ball of gas located in outer space. They are made of hot gasses and plasma.

They are born in a nebula which is a large cluster of stardust. Many stars perform nuclear fusion, where hydrogen nuclei combine to create helium. This provides stars energy to burn and prosper for billions of years.

When a star is dying it will begin to lose its power. It will eventually explode in an enormous supernova. This has a chance of creating a black hole. Usually the remnants of the supernova will form another nebula, therefore continuing the cycle of a star.

I hope this helps!

A scientist measures the growth of a bamboo plant over time. The table above shows the results. What is the best interference fo
lisabon 2012 [21]

(B) 2.25cm

<u>Explanation:</u>

Given:

At 40 hours, the height of the bamboo plant is 2.1cm

At 50 hours, the height of the bamboo plant is 2.4cm

Height of the bamboo plant after 45 hours = ?

The difference in length from 40 to 50 hours = 2.4 - 2.1cm

                                                                      = 0.3 cm

Mean of 40 and 50 is 45.

Thus,

At 45 hours, the height will increase by 0.3/2

                                                         = 0.15 cm

Height at 45 hour = 2.1 + 0.15cm

                           = 2.25cm

Therefore, the height of the plant after 45 hours is 2.25cm
