A hydraulic press consist of of two cylinders of cross sectional areas
0.2m2 and 5m². The piston in the
smaller cylinder is pushed down
with a force of 100N through a
distance 0.2m. calculate

The pressure transmitted
(ii)
The force exerted by the
piston in the larger cylinder. ​

Explanation:

i )

area of small piston = 0.2 m²

Force = 100 N

pressure created on small piston

= 100 / .2 = 500 N/m²

According to Pascal's law , this pressure will be transmitted to larger cylinder .

area of larger cylinder = 5 m²

ii )

pressure = force / area

force in the large cylinder = pressure x area of large cylinder

= 500 x 5

= 2500 N .

the closer the planet is to the sun, the larger the gravity

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
