Answer:
The value is 
Explanation:
From the question we are told that
The number of turns is N = 1000
The length is L = 50 cm = 0.50 m
The radius is r = 2.0 cm = 0.02 m
The current is I = 18.0 A
Generally the magnetic field is mathematically represented as

Here
is the permeability of free space with value

So

=> 
Answer:
As much I know the gravity on moon is 1.62m/s२.
Momentum = mass x velocity
So both mass and velocity affect an object's momentum.
