Answer:
You could put over six planets the size of Mars inside the Earth. The largest planet in our Solar System, Jupiter's size is astounding. Jupiter has a volume of 1.43 x 1015 cubic kilometers. To show what this number means, you could fit 1321 Earths inside of Jupiter
Explanation:
Similar properties. Cause they have the same number of valence electrons
Answer: If a star's radial velocity is -50 km/s, the frequency of its light would appear to be higher than its true frequency. We usually say that the star's wavelength is blue shifted.
Explanation:
Radial velocity is defined as the velocity of how an object is seen by the axis of a circle.
Then, if the radial velocity is -50km/s, this means that the radius is decreasing, and then that the star is coming towards the viewer.
as the star is coming towards the viewer, we will see a shorter wavelength, which implies that the frequency would appear to be bigger as it really is.
and this is called a blue shift, because the blue light is the visible light with the biggest frequency, while the red light is the visible light with the smallest frequency, then we have:
If a star's radial velocity is -50 km/s, the frequency of its light would appear to be higher than its true frequency. We usually say that the star's wavelength is blue shifted.
Answer:
Explanation:
From the vertical movement, we know that initial speed is 0, and initial height is H, so:
solving for t:
Now, from the horizontal movement, we know that initial speed is V and the acceleration is -g/4:
Replacing values:
Simplifying:
Answer:
C) 1 and 4
Explanation:
Least count is .01 m . If one measures any number between 100 and 99 , it will be like 99.25 or 99.37 m . So number of significant figure will be 4 ( maximum )
The least one can measure is .01 so least number of significant figure possible is 1 .
