1.	Whichof the diagrams in figure correctly shows the change in kinetic energy of an iron sphere falling freely in a lake having sufficient depth to impart it a terminal velocity ?
Answer» Solution :INTIALLY ,velocity of the ironsphere increases and after SOMETIME becomes constant ,called TERMINALVELOCITY .Hence ,INITIALLY KE increases and then becomes constant which is REPRESENTED by .
