Question 6 Exercise 2C

A body starts from rest with a uniform acceleration of 2m/s. Find the distance covered by the body in 2s.

Answer:

Given:

u=0; a=2m/s^2 ; t=2s

v = u + at

= 0 + 2 x 2

v = 4m/s

distance travelled, s=ut+\frac{1}{2}at^2

= 0(2) + ½ (2) (2.2)

= 0 + 4

= 4m

hello welcome to leader today we are going to see in which arrangement are the appealances connected in a circuit of the out home series are parallel okay series are parallel and view reasons appealing in our home are arranged in parallel circuits heads are going to be error like this it's going to be a parallel circuit like this it's not going to be a c circuit but it's going to be in a parallel okay it's going to be a battery it is going to be parallel parallel circuits and which is why our opinions work independently it's going to be like independent right it does not depend on these to work like this okay sometimes you are only on the fan and you don't earn pulp okay if you want to only on the fan you're running this thing okay if you if it is connected in series what happens you know if you on fan it's going to on all the things okay other things are going to be on so we do not require like this right so we are going to connect that to avoid this interruption we are going to connect in the parallel circuits okay so i hope you understood this video subscribe to the channel for regular updates and thanks for watching this video
