Answer:
a = 0.8 [m/s²]
Explanation:
To solve this problem we must use Newton's second law which tells us that the resulting force on a body is equal to the product of mass by acceleration, in this way we come to the following equation:
∑F = m*a
where:
F = forces applied [N]
m = mass = 1000 [kg]
a = acceleration [m/s²]
Now using Newton's second law.
![1200 - 400 = 1000*a\\800 = 1000 *a\\a=0.8[m/s^{2} ]](https://tex.z-dn.net/?f=1200%20-%20400%20%3D%201000%2Aa%5C%5C800%20%3D%201000%20%2Aa%5C%5Ca%3D0.8%5Bm%2Fs%5E%7B2%7D%20%5D)
Yes, while he is sitting he is reading something to prepare him to finsh a job. reading instructions can be considered step one in starting a job. ex-before builders are able build, they must read the blueprints in order to know what to do.

Although scientists can't detect or observe black holes with telescopes that detect x-rays, light, or other many other different forms of electromagnetic radiation and waves. But they can detect and study them by the effect of matter near it. If a black hole passes through a cloud of interstellar matter, it will draw matter inward (this process is known as accretion). A similar process occurs when a star passes through a black hole. When this happens, a star can break apart as it pulls it self toward it. As the attracted matter accelerates and starts heating up, it emits x-rays that are radiate into space.
Recent studies do show that black do have a very big influence towards neighborhoods around it. The black hole emits gamma ray bursts, devouring nearby stars, and spurring the growth of new stars in some areas while stalling it in others.
