Answer:
The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.
The Socrates' natural philosophy was just the most important founding figures in the western philosophy.
Darwins penguins rule; Darwin only established the Golden Rule.
Einstien's physics: Einstiens theory of relativity is the most important scientific idea of the modern era.
Newtons principle: Physics Science Newtons Laws of Motion. (This is the ANSWER)
Hope this really helps!!! (:
a) 189.2 J
b) 13.5 W
Explanation:
a)
The work done by the force on the package is equal to the scalar product between force and displacement:
where F is the force and d is the displacement.
In this problem, the force is:
We know the initial position:
and the final position:
So, the displacement is the difference between the two positions:
Therefore, the scalar product between force and displacement is:
b)
The average power of the machine is the rate of work done per unit time; it is given by
where
W is the work done
t is the time elapsed
In this problem, we have:
W = 189.2 J (work done)
t = 14.0 - 0 = 14.0 s (time elapsed)
Therefore, the average power of the machine is:
Answer:
If there is a system of magnets being held in place, there is potential energy. When you let go the potential energy makes to kinetic energy and the magnets move.
molecular cloud <interstellar cloud <1 Msun protostar <1 Msun star <intercloud gas
Explanation:
<u>Molecular cloud-</u> They are a variety of interstellar cloud in which molecular hydrogen can sustain themselves. They have a very low temperature ranging from -440 to -370 degrees Fahrenheit or between<u> 10 to 50 Kelvin. </u>Owing to their extremely low temperature, they appear mostly dark when viewed through telescopes.
<u>Interstellar cloud-</u> They are a congregation of a large number of interstellar gases, dust and plasma in any galaxy or universe. They have varying temperature depending on their proximity to a star. E.g. Neutral hydrogen atom clouds have a temperature of around <u>just 100 Kelvin</u> while those in the near vicinity of a star have temperatures as high as 10,000 Kelvin.
<u>1 Msun star-</u> These stars have temperature anywhere between <u>5300 and 6000 Kelvin</u>. The main source of such high surface temperature is nuclear fusion process where elemental hydrogen molecules are fused to form helium molecules.
<u>1 Msun protostar-</u> protostar is rather a young star which is still in formation phase (i.e. gathering mass from the parent molecular cloud). They have temperature anywhere between <u>2000-3000</u> kelvin and are accompanied by dust usually.
<u>Intercloud gas- </u>These are the remainder gases that are spread throughout the interstellar space. This Intercloud gas is divided into warm intercloud medium and extremely hot coronal gas with temperatures comparing to Sun’s corona. Warm intercloud forms the dominant part of intercloud gas with a temperature around <u>8000 Kelvin</u>.
