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
One path because in a series circuit it is only one path while in a parallel circuit you have 2 or more. Our houses use parallel so that is why you can turn off one light and the rest would stay on.
Answer
given,
mass of an object = 5 Kg
mass of the other object = 5.98 x 10²⁴ Kg
radius of earth = 6371 Km = 6.371 x 10⁶ m
comparison between gravitational force between two object and weight of the object.
gravitational force between two objects


F = 49.134 N
weight of the object on the earth surface
F = m g
F = 5 x 9.81
F = 49.05 N
From the above two calculation we can conclude that gravitational force is approximately equal to weight of the body.
The equations are
