The singularity at the center of a black hole is predicted to be a region of zero volume and infinite density that contains all of the black hole's mass. It is a point at which all currently known physical laws break down. Yet in a black hole, this "terrible point" is hidden from view behind an event horizon that prevents any knowledge about the singularity reaching the outside universe. Astronomers continue to spend considerable effort trying to understand the nature of these singularities, objects for which observational input, it would seem, will be forever lacking? Are these astronomers practicing science? Argue both yes and no. Which do you find convincing?

Yes

Explanation:

Science is a quest to find answers and patterns in the universe which can then be relied on for predicting future occurrence. Finding these singular points or at least to some extent, the cause and formation of this point will help with our further and deeper understanding of the universe, and we can then be able to predict when, where or when this singularities occurs.

No

Explanation:

Spending a lot of time on these singularities that are hidden from view behind an event horizon that prevents any knowledge about the singularity reaching the outside universe is an absolute waste of time. This reflects no practice of science, since science is all about finding answers. If these answers we seek to find no matter how much we probe, cannot be gotten from further studies of these occurrences then it will be best to leave what can't be found. The fact that all known laws of physics breaks down at these point is a pointer that any physical means that will be employed to probe these singularities will yield no result within our known physical laws.

I will go with yes, with hope that advance in science will someday break these barriers or reconcile our known laws of physics with whatever physical law prevails within these singularities.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
