<span>Boyle's Law states that there is an inverse relationship between volume and pressure when temperature is held constant. Therefore, according to this law, if the pressure of a balloon is increased, the volume of that balloon will subsequently decrease.</span>
Answer:
Explanation:
Calculating the exit temperature for K = 1.4
The value of
is determined via the expression:

where ;
R = universal gas constant = 
k = constant = 1.4


The derived expression from mass and energy rate balances reduce for the isothermal process of ideal gas is :
------ equation(1)
we can rewrite the above equation as :


where:



Thus, the exit temperature = 402.36 K
The exit pressure is determined by using the relation:



Therefore, the exit pressure is 17.79 bar
Answer:
Both forces are the same.
Explanation:
The problem states that:

The force exerted on the moon by earth is given by:
where K is the gravitational constant, and d is the separation distance between the earth and the moon.
The force exerted on the earth by moon is given by:
where K is the gravitational constant, and d is the separation distance between the earth and the moon.
The relation is therefore:

As you can see, they are the same.
P.E=0.0675 J
Explanation:
Elastic potential Energy=Force × distance of displacement
The formula to apply is;
P.E=1/2 ks²
where k is the spring constant given as; 1.5 *10^-2 N/m and s is the displacement
In this case,
s=3
P.E= 1/2 * 1.5 × 10^-2 ×3²
P.E=1.5×10^-2*4.5
P.E=0.0675 J

Incompletevquestion. However, I inferred from a general perspective about perpendicular lines.
<u>Explanation:</u>
Put simply, <u>perpendicular lines</u> are lines that are at right angles (90°) to each other. Thus, we could say based on this definition that for lines lll and mmm to be perpendicular they intersect and be at right angles (90°) to each other as <u>found on the attached image.</u>
