An iron ball falling form a height of 100m. Calculate the time taken by the iron ball to reach the ground.
Answers
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....................................
