Calculate the maximum pressure exerted by the cuboid of mass 800 gram having Dimensions 24cm, 20cm and 16cm respectively.(g=10ms-2).
Answers
Answer:
250Pascal
Explanation:
before answering this question i will ask you what is formula for pressure
it is FORCE/AREA.
WHAT IS area OF A RECTANGLE
IT IS l x b
WHAT IS FORMULA FOR FORCE
IT IS MASS X GRAVITATIONAL ACCELERATION.
THAT'S IT !!!
WE WILL USE THESE FORMULAS ONLY TO SOLVE THIS QUESTION!!
SO LETS CONTINUE WITH OUR QUESTION...
MASS=800G=0.8kg
g=10M/S²
MULTIPLY THEM
ANS IS 8Newton
we got our force!!!
next is area
now this is a cuboid so we have to choose 2 of the dimensions
it is given max pressure.
to get max pressure we have to choose min AREA.
NOW THE BOTH ARE IN CMS SO MAKE THEM INTO M
YOU WILL GET AS 0.20 AND 0.16 ,cos we want max pressure.
multiply them=0.032
divide them
8/0.032=8000/32=250
so the answer is 250 Pascal
hope it helps!!!!
pls mark my answer brainliest.
