Longitudinal waves causes the medium to vibrate only in a direction parallel to the wave's motion
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
Answer:
The quantities which do not depend on other quantities is called fundamental qiantity. For eg; time,current,lwngth etc...
The solution would be like this for this specific problem:
T = 2 * pi * sqrt (Length / g)
T = 2 * 31.4 * sqrt
(1.8m / 3.69 m/second2)
T = 4.386142257432951112677107108824

Answer:
Explanation:
the weight of the telescope decreases because the moon attract the body with less force as compared to earth due to less gravity as compared to earth
