A satellite with a mass of 100 kg fires its engines to increase velocity, thereby increasing the size of its orbit about Earth. As a result, it moves from a
circular orbit of radius 7.5 x 106 m to an orbit of radius 7.7 x 106 m. What is
the approximate change in gravitational force from Earth as a result of this
change in the satellite's orbit? (Recall that Earth has a mass of 5.97 x 1024 kg
and G = 6.67 10-11 N·m2/kg2.)
O A. -36 N.
O B. -16 N
O C. -24 N
D. -SN

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)
