A force that cannot produce equilibrium with these two forces must be less than 7 N or greater 7 N.
The given parameters;
- <em>3 Newton force </em>
- <em>4 Newton force</em>
A body is said to be in equilibrium state when the net force on the body is zero.
A force that produce equilibrium among two forces acting concurrently is known as equilibrant force. This force is usually equal to sum of the two concurrent forces.
where;
- F₁ and F₂ are the concurrent forces
- F₃ is the equilibrant force
From the given parameters;
Thus, a force that cannot produce equilibrium with these two forces must be less than 7 N or greater 7 N.

Answer:
(D) all of the above
Explanation:
The molecules in a gas interact weakly with each other, without forming molecular bonds, because of this its highly compressible. A gas adopt the shape and volume of the recipient that contains them and tend to expand, due to the high amount of kinetic energy of their molecules.

Answer:
Tension, Ft = 79.91 N
Explanation:
The tension in the string is the resultant force that exists in the string due to the centripetal effect of the swinging ball.
From conservation laws, the tension in the string will be equals to the centripetal force acting on the string.
The tension in a string can be obtained using the formula:
where v = linear velocity of the metal ball which equals to the angular velocity of the ball X the radius of the ball.
The radius of the ball is given as 72 cm = 0.72m and the angular velocity = 1.02 rad/second.
Therefore, linear velocity, 
The tension in the string will now be equals to
