Answer: b
Step-by-step explanation:
You know the formula of a triangle is: (base*height)/2
So: 4*8=32
32/2=16cm^2
Since its a parallelogram, you could say that there are two of these triangles, so: 16*2=32cm^2
Now we're left with the part in the middle. The sides are now 8 by 8 because we took away 4 from 12, so: 8*8= 64cm^2
Now you just add all your values together, so: 32+64=96cm^2
The answer is 26 Pa.
<span>The ideal gas law can be presented as:
PV = nRT
where
P - pressure of the gas,
V - volume of the gas,
n - amount of substance of gas,
R - gas constant,
T - temperature of the gas.</span>
But, we do not need to know all of the equation members since the right side of the equation is not affected and will remain the same. It is enough the left side of the equation:
P₁V₁ = P₂V₂
It is given:
P₁ = 104 Pa
V₁ = 108 L
V₂.= 432 L
The unknown is P₂ = ?
P₁V₁ = P₂V₂.
104 Pa × 108 L = P₂ × 432 L
11,232 Pa L = P₂ × 432 L
P₂ = 11,232 Pa ÷ 432
<span>P₂ = 26 Pa</span>
<span>
</span>
<span>Therefore, the new pressure will be 26 Pa.</span>
