A dentist's chair with a person in it weighs 1675 N. The output plunger of a hydraulic system starts to lift the chair when the
1 answer:
The ratio of the area of the plunger to the area of the piston will be 0.2323.
<h3>What is pressure?</h3>
The force applied perpendicular to the surface of an item per unit area across which that force is spread is known as pressure.
It is denoted by P. The pressure relative to the ambient pressure is known as gauge pressure.
The presure at the output remains the same
Hence, the ratio of the area of the plunger to the area of the piston will be 0.2323.

.
Explanation:
In a double replacement reaction, two ionic compounds exchange their ions to produce two different ionic compounds.
In this question, the two ionic compounds are:
, and
.
In particular,
ions and
ions, while
ions and
ions.
In a binary ionic compound, cations (positive ions) can only bond to anions (negative ions.)
.
.
Hence, the two products will be and
.
Note that charges on the ions must balance. For example, a ion carries twice as much charge as an
ion. As a result, each
ion would bond with twice as many
ions as
would in
