PLZZZZ HELP ME!!!!!!!!!!! will give brainliest and 20 points why is pinball used to describe the steps in the scientific process
ozzi
Well, I'm not completely sure, but, I'm going to try and help you: First, you would need to observe the machine, which, would represent the first step. Secondly, you would have to ask yourself a question, when the ball shoots out, which way are you going to hit it? Next, you'd have to hypothesize, which way the ball will come, which way will give you the most points. etc, etc. Then, you'd make a prediction based on your hypothesis, predict the direction that will give you the most points, and which way the ball will fall. Now, when the ball shoots out, you'd gave to test your prediction, then you'd see if your hypothesis was correct. Lastly, you would iterate, and, come up with new hypotheses, and, predictions, for when you play on round two, this would, also, help you get better at the game, just as, when you perform other scientific experiments, you would have a better idea on what would happen during them. I hope this helps!!!

Answer:

Number of atoms = 5.1345 x 10²³

Explanation:

Given:

Mass of sodium = 19.6

Find:

Number of atoms

Computation:

We know that atomic mass of sodium is 22.98

So,

Number of atoms = [Mass of sodium/atomic mass of sodium]Avogadro's number

Number of atoms = [19.6 / 22.98]6.02 x 10²³

Number of atoms = 5.1345 x 10²³
