Explanation 1) Concept: Magnitude of the vectors can be found by performing simple mathematical operations on the given vectors using the law of vector addition. Magnitude can be found by using the formula for magnitude. 2) Formulae: i. A → + B → = A x + B x i → + A y + B y j → ii. A → - B → = A x - B x i → + A y - B y j → iii. A → = A x 2 + A y 2 3) Given: i. A → + B → = 6.0 i ^ + 1.0 j ^ ii. A → - B → = - 4.0 i ^ + 7.0 j ^ 4) Calculations: To determine the magnitude of A → , we need to find the A → first. We add the two equations in vectors as follows: A → + B → = 6.0 i ^ + 1.0 j ^ + A → - B → = - 4

Kinetic Theory of Gas

The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all dire…
