Answer:
it means that velocity of a body rises by 9.8m/s each second if the air resistance is nrelated
mark me
Answer:
Power = Current × Voltage
Explanation:
Units:
Power = Watts
Current = Àmperes
Voltage = Volts
To solve this problem we will apply the concepts related to the kinematic equations of linear motion. For this purpose we will define the speed as the distance traveled in a given period of time. Here the distance is equivalent to the orbit traveled around the earth, that is, a circle. Approaching the height of the aircraft with the radius of the earth, we will have the following data,



The circumference of the earth would be

Velocity is defined as,


Here
, then

Therefore will take
s or 506 hours, 19 minutes, 17 seconds
