Answer:

IF DENSITY IS GIVEN THEN WE SHOULD USE THE FORMULA OF

DENSITY =MASS/VOLUME

NOW, IF IT IS ASKED TO FIND MASS THEN MULTIPLE THE OTHER TWO OTHER THINGS LEFT AND ALSO THEN IF VOLUME DO SAME

Explanation:

NOW YOUR ANSWER

GIVEN:

HEIGHT OF IRON BALL FALLING IS 100 METRE

KNOW HERE !

DENSITY OF IRON IN KG M-³ IS 7800

DENSITY OF IRON IN G M-³ IS 7.8

SO, HERE WE ONLY TAKE KILOGRAM RULE

● ACCORDING TO FORMULA

● => WE GET ,

●=> (7800 KG M-³) / 100 M

●=> NOW HERE, 7800 (TWO ZEROS) AND HERE, 100 (TWO ZEROS) SO, BOTH ZEROS CANCELS OUT AND LEFT IS

●》78 AND THIS SIDE 1

●-》 NOW, 78 ×1

SO, WE GET FINAL ANSWER 78

VERY MUCH IMPORTANT

MANY A PEOPLE AFTER THEY DIVIDE THEN AGAIN DIVIDE 1 WITH 78 IN THIS CASE . BUT WE SHOULDN'T DO IT

REASON IS THAT

BODMAS RULE WE SHOULD FOLLOW

BODMAS STANDS FOR BRACKETS OF DIVISION ,MULTIPLICATION, ADDITION, SUBTRACTION

HOPE IT HELPS YOU....................................
