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…

Four capacitors are connected as shown in the figure below. (Let C = 12.0 µF.) A circuit consists of four capacitors. It begins at point a before the wire splits in two directions. On the upper split, there is a capacitor C followed by a 3.00 µF capacitor. On the lower split, there is a 6.00 µF capacitor. The two splits reconnect and are followed by a 20.0 µF capacitor, which is then followed by point b. (a) Find the equivalent capacitance between points a and b. µF(b) Calculate the charge on each capacitor, taking ΔVab = 16.0 V. 20.0 µF capacitor µC 6.00 µF capacitor µC 3.00 µF capacitor µC capacitor C µC
