Answer:
true
Explanation:
Some factors of heart disease cannot be controlled. A diet rich in high-density lipoproteins (HDLs) can help cleanse and open arteries that are clogged with plaque. Exercise can help prevent heart disease but once you've had a heart attack, it's too late for exercise to help you.
Interesting question. I'd take a guess that it could be either mirrors and light travelling in straight lines and being reflected, or optical fibres to achieve a perhaps similar result.
Answer:
Therefore the answer is the precision in the speed DECREASES
Explanation:
In quantum mechanics, we have the uncertainty principle that establishes that when the accuracy of the position increases the accuracy the speed decreases, being related by the expression
Δx Δv ≥ h'/ 2
h' = h/2π
Therefore the answer is the precision in the speed DECREASES
