Explanation:
The relay is an electromagnetic device, which is stimulated by a very weak electrical current to open or close a circuit. It functions as a switch controlled by an electrical circuit in which, by means of a coil and an electromagnet, a sequence of one or several contactors is activated that allow to open or close other electrical circuits independent of the one that controls it.

Acceleration, in physics, is the rate of change of velocity of an object. An object's acceleration is the net result of any and all forces acting on the object, as described by Newton's Second Law.
Pluto is a dwarf planet that's why
The position of John at time of 4.35 s is -1.13 m
From the given chart;
- at time, t = 0, the initial velocity, u = - 2 m/s
- at time, t = 5 s, the final velocity, v = 2 m/s
The average acceleration is calculated as follows;

The position of John at time, t = 4.35 s is calculated as follows;
Thus, the position of John at time of 4.35 s is -1.13 m
