Answer:

P₁ = 219.3 Pa

Explanation:

This fluid mechanics problem, we can use that the pressure is distributed with the same value throughout the system, which is Pascal's principle.

Let's use the subinidce1 for the small diameter and the subscript 2 for the larger diameter.

              P₁ = P₂

pressure is defined by

             P = F / A

we subtitute

             F₁ / A₁ = F₂ / A₂

             F₁ = F₂ A₁ / A₂

the area in a circle is

             A = π r² = π d² / 4

we substitute

            F₁ = F₂ (d₁ / d₂)²

we calculate

           F₁ = 17640 (2/32)²

           F₁ = 68.9 N

Having the force to be applied we can find the air pressure on the small plunger

          P₁ = F₁ / A₁

          P₁ = F₁ 4 / π d₁²

let's calculate

          P₁ = 68.9 4 / (π 0.02²)

          P₁ = 219.3 Pa

A food refrigerator is to provide a 15,000 kj/h cooling effect while rejecting 22,000 kj/h of heat. calculate the cop of this re
svp [43]
Coefficient of performance or more commonly known as COP is calculated through the equation,
                                 COP = ((T₂)/(T₂ - T₁)) 
where T₂ is the hot temperature and T₁ is the cold temperature. Similarly, these can also be,
                      COP = heat ejected / (heat ejected - heat provided)
 Substituting,
                     COP = 22,000 / (22,000 - 15,000) = 3.14
Thus, the value of the COP is approximately 3.14.

Iron filings scattered around a magnet will be most strongly drawn toward the _____.
victus00 [196]
<span>The answer is towards <span>the poles. This is because, at the poles of the magnet, the magnetic field lines get closer together hence indicating that the magnetic force is stronger here. The fields are closest together at the center of the magnet and farthest at the outside side of the magnet. </span></span>
