Plate tectonics may affect organic evolution because movement of plates may cause a change in the environment
Answer: 8.242 × 10 exp -8 N
Explanation: F = G *m* M/r^2
r = √(13-5)^² + (51-15)^² + (0-0)²
r = 8; the distance between the masses
G =6.673 × 10 -¹¹ Nm²kg-²
F = gravitational force of attraction of m(51kg) on M {1550kg)
This would be an example of active immunity
