Answer:
Explanation:
The law of gravitation
Universal gravitational constant [S.I. units]
Mass of Earth [S.I. units]
Mass of a man in a spacecraft [S.I. units]
Earth radius [km]
Distance between man and the earth's surface

Answer:
The velocity is 60 km/hr.
Explanation:
<h3><u>Given:</u></h3>
Displacement (d) = 480 km = 48000 m
Time (t) = 8 Hours = 480 minute
Velocity (v) = ?
Now,
Velocity = Displacement ÷ Time
v = d/t
v = 480/8
v = 60 km/hr
Thus, The velocity is 60 km/hr.

<h3>How would one describe air resistance?</h3>
- Air exerts a force known as air resistance. The force works in the opposite direction of an object traveling through the air.
- While a sports vehicle with a streamlined design will encounter reduced air resistance and experience less drag, the automobile will be able to move more quickly than a truck with a flat front.
<h3>What Causes Air Resistance?</h3>
- Air resistance, also referred to as "drag," is a force brought on by air. When air specks collide with an object's front, it slows down.
- The more air particles that impact the object and the larger its surface area, the more resistance it faces.

4. bc it is softer--made of a different material-- has a weaker reaction force
5. the sand would not leave footprints and would rather act as a whole
6. there is no gravity in outer space-- she can just float back to the spaceship no problem!
