An artificial satellite orbits Earth at a speed of 7800 m/s and a height of 200 km above Earth's surface . The satellite experiences an acceleration due to gravity of 9.8m/s2
0m/s2
less than 9.8 but greater than zero
39m/s2
Please give full explanation

The earths atmosphere is made up of nitrogen and oxygensolids turning into gases is called sublimation.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

The rearrangement of particles in a physical change. hope this
