The Earth's radius is 6371 km. So that's our distance from the center when we're on the surface.
The Shuttle astronaut's distance from the center, when s/he's in orbit, is 330 km greater ... that's 6701 km.
The force of gravity is inversely proportional to the distance between the center of the Earth and the center of the astronaut. So, in orbit, it's
(6371/6701)^2 = 90.4 %
of its value on the surface.
Relative time is the physical subdivision of the rocks found in the Earth's geology and the time and order of events they represent. Absolute time is the measurement taken from the same rocks to determine the amount of time that has expired
Explanation:
the correct answer is no ;)
Answer:
volume of substance of weight of mercury is 13593 kilograms
Answer:
1404 m
Explanation:
Given that
Depth of ocean = 780 fathoms
Given that
1 fathoms = 1.8 metes
1 fathoms = 1.8 m
Therefore 780 fathoms
1 x 780 fathoms = 1.8 x 780 m
780 fathoms = 1.8 x 780 m
780 fathoms = 1404 m
Therefore the depth of the ocean in meters will be 1404 m.
Note- A fathom is a unit of length equal to 6 feet (1.828 m) in the imperial and U.S. customary systems, especially used to measure water depth in the ocean. In such an imperial fathom there are two yards (6 feet).
