Answer:
atm
Explanation:
The pressure at the bottom of any liquid column is equal to product of density of the liquid , gravitational acceleration constant (g) and height of the water column
Thus,
Substituting the given values, we get -
kg/m3
m/s^2
meters
atm
The Correct choice is ~

Answer:
Explanation:
The amount of work done by Devin when moving the lawn is given by:
where
F is the average force applied
d is the displacement of the lawn
is the angle between the direction of the force and the displacement
Assuming that Devin moves the lawn by applying a force parallel to the displacement, we have:
F = 75 N
d = 1.5 km = 1500 m
Therefore, the work done is
