The Earth's Radius is 6.3710x106 m and mass is 5.9742x1024 kg. What is the acceleration due to gravity at Mount Everest (elevati
Shalnov [3]

Answer is

9.773m/s^2

-----------------------------------------------------------------------------

Given,

h=8848m

The value of sea level is 9.08m/s^2. So, Let g′ be the acceleration due to the gravity on Mount Everest.

g′=g(1 − 2h/h)

=9.8(1 - 6400000/17696)

=9.8(1 − 0.00276)

9.8×0.99724

=9.773m/s^2

Thus, the acceleration due to gravity on the top of Mount Everest is =9.773m/s^2

-----------------------------------------------------------------------

hope this helps :)

You observe a star system for many weeks. The light curve does not show significant changes in brightness, but a series of spect
mariarad [96]

Based on the changes in the light curve and the behavior of the series of spectra, this is a<u> binary system. </u>

<h3>How is this is binary system?</h3>

The characteristics described are those of a binary system with the specific type of system being the spectroscopic binary system.

This is because in a spectroscopic binary system, there won't be significant changes in brightness but as a result of stars orbiting towards and then away from us, spectral features will appear as alternative absorption lines.

In conclusion, this is a binary system.
