dispacement of the mosquito is​

Answer 1

Displacement of mosquito will be : See attached pic

Answer 2

Answer:

$\sqrt{43\\}$

Explanation:

Displacement is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position. For example- If an object moves from A position to B, then the object's position changes. Displacement = velocity x time. If an object is moving with constant acceleration, then the equation of third law of motion is used to find displacement: S = ut + ½ at2. S=v2−u22a. where v = final velocity, u = Initial velocity, s = displacement, and a = acceleration.

Displacement between two points

A( -1, 2, 3, ) , B( 2, -1, -2 )

AB= $\sqrt{(x_{2}- x_{1 })^{2} +(y_{2}- y_{1 })^{2} +(z_{2}-z_{1 })^{2}}$

AB=$\sqrt{(2+1)^{2} + ( -1-2)^{2} +( -2-3 )^{2} }$

AB = $\sqrt{9+ 9 + 25 }$ =$\sqrt{43}$

AB = 6.557
