Answer:
A hydraulic press works on the principle of Pascal's law, which states that when pressure is applied to a confined fluid, the pressure change occurs throughout the entire fluid. Within the hydraulic press, there is a piston that works as a pump, that provides a modest mechanical force to a small area of the sample.
Explanation:
I think the correct answer from the choices listed above is the second option. In Niels Bohr’s model of the atom, electrons move like planets orbiting the sun. His model of atom is seen as<span> very small, positively charged nucleus which contains proton and neutron surrounded by negatively charged electrons.</span><span> These electrons travel in circular orbits around the nucleolus. </span>
You’re traveling be same distance, but since it’s at a higher speed, you’re going faster than you were before. This meaning that it will take less time.
Answer:
C) Amplitude.
Explanation:
By definition, the amplitude of wave is defined as the distance from the rest position to the highest or lowest point of the wave.
The highest and lowest points of the wave are called crests and troughs respectively; Therefore, the amplitude of the waves is also said to be the height of the wave from its rest position to its crest—and also the height of the from the rest position it its trough.
This means Choice C (amplitude) is the correct term used to describe the height of a wave from its rest position to its crest.
<em>P.S: Choice A, the crest height, can also be the correct term, but the term ''amplitude'' is often used and is more technical. </em>
The error in the measurement of sin 90 degrees at the given error in angle is 0.001.
<h3>
Error in measurement</h3>
The error in measurement is obtained from the difference between the actual measurement and the observed measurement.
The error of sin 90 degrees is calculated as follows;
Actual measurement = sin 90 = 1
Observed measurement = sin(90 - 0.5)
Observed measurement = sin(89.5) = 0.999
<h3>Error in measurement of sin 90 degrees</h3>
<em>Error in measurement = Actual measurement - Observed measurement </em>Error in measurement = 1 - 0.999
Error in measurement = 0.001
Thus, the error in the measurement of sin 90 degrees at the given error in angle is 0.001.
