option c is right

Answer 2

GIVEN; MASS OF OBJECT = 45 N

DIMENSIONS OF SURFACE OF OBJECT = 15 M × 20 M

TO FIND ; PRESSURE ON OBJECT GIVEN.

SOLUTION;

AREA OF OBJECT'S SURFACE = LENGHT × BREADTH = 15 × 20

=> 300 M^2

AS WE KNOW,;

PRESSURE OF OBJECT = FORCE / AREA

THEN, SUBSTITUTING GIVEN VALUES OF FORCE AND AREA IN FORMULA;

=> PRESSURE = 45 N / 300 M^2

=> PRESSURE = 0. 150 PASCALS

SO ,THE OPTION ( A ) IS CORRECT , PRESSURE ON OBJECT IS 0.150 PASCALS.

THANKS FRIEND, HOPE IT HELPS YOU .
