Answer:
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. Wikipedia
In SI base units: kg·m/s2
Other units: dyne, pound-force, poundal, kip, kilopond
Derivations from other quantities: F = m a
SI unit: Newton
Explanation:
We know that: If A is a square matrix of order n and its determinant is |A| Then for any scaler k , |kA| = k^n|A| Here n is 3 , so |3A| = 3^3|A| = 27|A|
