Which of the following conditions would always result in a net force of 0N?
2 answers:
A condition which would always result in a net force of zero (0) Newton is: A. Two equal but opposite forces act on an object.
Newton's Second Law of Motion states that the acceleration of an object is inversely proportional to its mass and directly proportional to the net force acting on the physical object.
Mathematically, Newton's Second Law of Motion is given by this formula;
According to Newton's Second Law of Motion, the acceleration of a physical object occurs when there is a net force on an object while a net force (sum of all the forces) zero (0) causes no acceleration.
In Science, an object is said to be at equilibrium when two equal but opposite forces are acting on it and this would always result in a net force of zero (0) Newton.

Answer:
Therefore the escape velocity from Mar's gravity is m/s.
Explanation:
Escape velocity: Escape velocity is a the minimum velocity that a object needs to escape from the gravitational field of massive body.
Escape velocity
G=Universal gravitational constant = 6.673×10⁻¹¹N m²/Kg²
M= mass of Mars = 6.42×10²³ kg
R = Radius of the Mars = 3.40×10³m
The escape velocity does not depend on the velocity of a object.
m/s
Therefore the escape velocity from Mar's gravity is m/s.
