25x = 200*30
25x= 6000
x= 240
The reason why it relates to the newtons 3 laws of motion because the first law of motion states that every object will stay at rest unless it's moved by an unbalanced force which is your hand. The second one states that <span> the velocity of an object changes when it is subjected to an external force meaning it's used by the equation that is commonly used for which is F=M*A. The way it relates to the second law because you are adding force some way or another, the mass is the egg and the acceleration is the drop of the egg while it free falls. And the last one, for a reaction there is always an equal or opposite reaction and the opposite reaction is the floor because it's going against the egg causing it to crack. If it was with the egg, it would have a soft, smooth landing.</span>
The ozone layer absorbs UV
(ultraviolet) radiation. The answer is letter C. the ozone layer is able to
oxidize the electros and photons in the UV rays so that the light that can pass
through can be not harmful to humans.
Answer:
With a person’s blood pressure is measured to be 120 ± 2 mmHg, it will be 1.2mmHg
Explanation:
What is missing in the question is the percentage of uncertainty.
If we assume that a person’s blood pressure is measured to be 120 ± 2 mmHg, the percent uncertainty is computed as:
% uncertainty = 2mmHg/120mmHg x 100% = 1.7%
So,
The uncertainty in the blood pressure is = 1.7% / 100% * 71mmHg = 1.2mmHg
