When a satellite is in orbit around the earth the force of gravity on the satellite-

Is always towards the center of the Earth

Explanation:

As a satellite moves around the Earth in a circular orbit, the direction of the force of gravity is always towards the center of the Earth. At an altitude of 100 km, you would be so high that you would see black sky and stars if you looked upwards.

d they tend to lose electrons and become cations.

explanation:

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5
