Answer:

The gravity is roughly the same. The inverse square law applies to gravity and that means that being 60 miles above Earth is about the same as being on Earth. The thing is, they are going really fast in an orbit and thus falling around the Earth. The weightlessness comes from a sort of cancellation of gravity pulling them down and their going perpendicular to that force. The forces are cancelling and making them relatively “weightless”. It’s not really weightlessness but just an equilibrium reached between the two accelerations of gravity and their motion against the pull of the Earth.

Oksana_A [137]
Velocity is distance/time 

so 150/7200=.0208km/s 

unless you have to convert it to miles or something else. but use the formula!

Marysya12 [62]
<span>its kinetic energy is 7350kJ 
</span>

Kinetic energy is given as = \frac{1}{2} mv^{2}

Now, m = 12 gms = 0.012 kg
 And, velocity = 35 kilometers/second = 35000 m/sec

Kinetic energy is given as = \frac{1}{2} 0.012 kg * 35000*35000 m/[tex] s^{2}
                        = 6 10^{-2}×1225 ×10^{6} m/s^{2} 
                        = 7350 kJ

vovangra [49]

Answer: 8m/s

Explanation:

Vs= 3 m/s

Vf=?

a=0.5m/s²

t=10s

-----------

a=Vf-Vs/t

at=Vf-Vs

0.5*10s=Vf-Vs

5m/s=Vf-3m/s

5m/s+3m/s=Vf

Vf=8m/s
