Question Discussion & Solution

The correct answer is Boy pushing wall in a room.

Key Points

• Boy pushing the wall in the room is not an example of work done.
  • When a boy pushes a wall, he is applying force on the wall. We see that the wall shows no displacement.
  • Work is given as the product of the forces and the displacement in the same direction.
  • Hence the work done is zero.

Additional Information

• Work is done when a force moves. Everyday examples of work include walking up a flight of stairs, lifting heavy objects, pulling a sled and pushing a shopping trolley, Applying pressure on a pebble lying on the surface, raising a book to a height.
  • Work is not done when holding a bag stationary or a book at arm's length because although a force is being applied, the force does not move.

The correct answer is Select, where, group by, having.

Additional Information

Six Operations to Order: SELECT, FROM, WHERE, GROUP BY, HAVING, and ORDER BY. Because the database executes query components in a specific order,

SELECT select_list [ INTO new_table ]  [ FROM table_source ]

[ WHERE search_condition ]

[ GROUP BY group_by_expression ]

[ HAVING search_condition ]

[ ORDER BY order_expression [ ASC | DESC ] ]

Hence Option 4 is correct

Statement: Should electric two wheelers be subsidized?

Argument:

I. Yes, Should electric two-wheelers be subsidized because electric two-wheelers do NOT create pollution. It prevents our country from pollutions and diseases related to pollution. Therefore, Argument I is strong.

II. Charging takes much longer than filling petrol. It means the charging process takes more time to charge and also consumes more electrical power and more time taking in comparison to petrol filling, but its cost is less than petrol. So, Argument II is not strong.

Here, we can say " Only Argument I is Strong".

Hence, "Only Argument I is Strong" is correct answer.
