Centripetal force of satellite = gravitational force between earth and the satellite
(m•v^2)/r = (G•Me•m)/r^2
v^2 = (G•Me)/r
v^2 = 6.67x10^-11 x 5.598x10^24 / 7.5x10^7
v = 2231 m/s
so answer is B
The branch of science concerning heat flow and energy conversions is
called thermodynamics. The pattern that takes place in the ecosystem regarding the
flow of energy is from a higher energy state t a lower energy state. It follows
the second law of thermodynamics, the entropy in which all things go into the
chaotic state from a higher form into lower form.

The botany phenomenon that is primarily based on an understanding of physics is t<span>he way plant pollen is carried by wind to another plant. It has to do with motion and acceleration, which are all the things that physics studies. </span>
When you ride your bike around a corner at 10 m/s, you are accelerating. Acceleration is caused by any forces. Sliding friction keeps you in the seat when a car goes around a corner. If you throw a ball into the air, Earth exerts a force on the ball.
False, because I doesn’t matter if there is noise pollution the child will still able to learn the way words work
