The approximate acceleration of gravity for an object above the earth's surface is 9.8 m/s².
<h3>
Acceleration due to gravity </h3>
The acceleration due to gravity of an object above the Earth's surface is calculated from Newton's second law of motion and Newton's law of universal gravitation.
<h3>Force between the object and Earth</h3>
<h3>Weight of the object</h3>
Solve (1) and (2)
mg = GmM/R²
g = GM/R²
where;
- M is mass of Earth
- G is gravitational constant
- R is radius of the Earth = 6,371 km
g = (6.673 x 10⁻¹¹ x 5.98 x 10²⁴)/(6,371 x 10³)²
g = 9.8 m/s²

The answer to your question would be false. It is true because duration can not lead to injury quickly.
In 1842, Julius Robert Mayer discovered The law of conservation of Energy. It its most compact form, it it now called The first law of Thermodynamics
Energy can neither be created nor destroyed, it can only be changed to another form of energy.
If you divide 68.5 km/h by 60 (the minutes in an hour) and then you get 1.141 then you multiply it by 5.45 and you get 6.222!
Your Answer is 6.222!!!!
B. their distances from the sun.
Explanation:
Absolute Magnitude:
Astronomers defines the absolute magnitude of a stars brightness in terms of how bright a star appears from a standard distance of 10 parsecs. Parsec is a unit of distance in astronomy. 10 parsecs is equal to 32.6 light years.
Apparent Magnitude:
Apparent magnitude of a star refers to how bright the star appears at its distance from the Earth.
If two stars have the same absolute magnitude but their apparent magnitude differs, the reason is that the distance of both the stars from the Earth varies. Hence their brightness differs when measured from Earth. The farther a star is from the Earth, the fainter its brightness.
