Answer:

Explanation:

ACCELERATION = <u>CHANGE IN VELOCITY </u>

                                          TIME  TAKEN

∴ a = <u>25 - 0 </u>

         10.5

∴ a =  <u> 50  </u>  

           21    

by using f = ma,

we get , f =   3950 ×  <u>50 </u>                                                                                  

                                     21

∴  A FORCE OF 9404.8 N IS NEEDED TO ACCELERATE A BUS OF 3950 KG.

krok68 [10]

Answer:

it is essential that the charge on the plates are of the same magnitude, but in the opposite direction

Explanation:

The configuration of parallel plates is called a capacitor and is widely used to create constant electric fields inside.

 To obtain this field it is essential that the charge on the plates are of the same magnitude, but in the opposite direction

This is so that the fields created by each plate can be added inside and subtracted from the outside of the plates
