A element or chemical that builds together
The greatest biodiversity on Earth is found in the tropical rainforest biome
Answer:0.61 m
Explanation:
Given
Initial velocity (u)=7.40 m/s
launch angle 
height of fence=0.7 m
Trajectory of Projectile is given by
For x=2.1 m
At x=2.1 m Y=1.31
therefore Fox clear fence by a margin =1.31-0.7=0.61 m
G=mg
649=10m
m=64,9kg
if we consider the gravitational acceleration 10m/s^2
