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
Answer:
is there suppose to be a pic?
Explanation:
Answer:
force exerted by the cat is 693 N
Explanation:
We know that total energy is the sum of work done by gravity and friction i.e.
solving for F
here -ve sign indicate work done in opposite direction
where, m is mass of cat = 4.00 kg
h = 2.00 m,
Putting all value in above equation
F = 692.53 N = 693 N
Therefore force exerted by the cat is 693 N
