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
<span>The following that describes the intercepts on the graph is "The initial velocity of the runner was 4 m/s, and the runner stopped after 8 seconds." It is because the starting point of the line is at 4 and then the ending point is at 8.

A radioactive isotope will release alpha particles and become more stable, and becomes a different element.
Answer: 1A
Explanation: for an ideal transformer, the relationship between number of turns and current is given below as
Ip/ Is = Ns/ Np
Where Ip = current in primary loop = 3A
Is = current in secondary loop =?
Np = number of turns in primary loop = n
Ns = number of turns in secondary loop = 3n
By substituting the parameters, we have that
3/Is = 3n/n
3/Is = 3
3 = 3 × Is
Is = 3/3 = 1A
Current in the secondary loop is 1A
