Can you post the question, on here? I cant open the document.
Answer:- 100
Explanations:- The given number is 124.683 and it has 6 significant figures. We are asked to round it to one significant digit number. To round it as one significant digit we need to make two second and third digits zero and all the three digits next to the decimal are dropped since we want only one significant digit. Second and third digits left to the decimal could not be dropped as they hold the place values. So, 124.683 is round to 100 that has just one significant digit.
Answer: The amount of substance of a system that contains as many elementary entities as there are atoms in 12 g of carbon-12
Explanation:
The answer is 0 Newtons
This is because of a key word in the question: “constant”
When we say something has a constant speed, that means that its acceleration is 0.
Using the equation derived for Newton’s 2nd law, we see that F=ma
Force = mass x acceleration
If acceleration, a, equals 0, then when we multiply our mass times acceleration 0
F=m(0)
Anything times zero equals zero
So, F=0
