The gravitational force exerted by an object is given by f 5 mg where f is the force in newtons, m is the mass in kilograms, and g is the acceleration due to gravity, 9.81 m/s². calculate the force exerted per unit of area by a column of mercury (density 5 13.59 g/cm³) that is 76.0 cm high. how high would a column of water (density 5 1.00 g/cm³) have to be to exert the same force?

Part a)

Part b)

Explanation:

As we know that force due to gravity is given as

now for force per unit area is given as

so for mercury we will have

Part b)

Now if water also apply same force per unit area

then we will have

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
