The frequency of the wave increases as it is the number of oscillations per second.
You would convert from grams to
moles by using the molar mass of the substance. The answer is letter B. for
example, the molar mass Carbon dioxide is 44.01 g/mol. It means that for 1 mole
of carbon dioxide, it contains 44.01 grams of Carbon dioxide.
The answer is D- it has a high resistance and is a conductor
hope this helps !
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
= 26.3 * 
= 2.63 *
N
