Question

match the following  section A with section B 

1)hydraulic lift
             a)charge is zero
2)purity of gold
              b)net charge is zero
3)acceleration
               c)pascal's law
4)energy
                      d)archimede's principle
5)neutral charge
           e)scalar quantity
             f)vector quantity

Answer 1

1) hydraulic lift                      a) charge is zero
2) purity of gold                    b) net charge is zero
3) acceleration                     c) pascal's law
4) energy                            d) Archimedes principle
5) neutral charge                  e) scalar quantity
                                           f) vector quantity

2 - d         Archemedes discovered the law, to find the purity of gold in the crown.
1 - c         Pascal's law - pressure is same at the same height in a liquid. 
               this is used to lift very heavy loads by hydraulic lift.
3 -  f          
5 -  b       uncharged particle means charge is 0.  neutral charge 
               means that there are equal and opposite charges present on a
               body  or at a location.
4   -   e

Answer 2

2 - d , 1 - c , 3 -  f , 5 -  b, 4   -   e
