8. Rocks are sometimes used along coasts to prevent erosion. If a rock needs to weigh 2,000 kg in order
not to be shifted by waves, how big (what volume) does it need to be? You are using basalt, which has

Answer 1

Answer:

Answer:

IT DECREASES

Explanation:

as gravity acts upon it and try to pull the ball, back to earth

Explanation:

Answer 2

Answer:

0.625 $m^{3}$

Explanation:

mass=2000kg

density=3200

as density=$\frac{mass}{volume}$

   volume=$\frac{mass}{density}$

   volume=$\frac{2000}{3200}$

               =0.625 $m^{3}$
