deff fn [24]

Explanation:

Kirchhoffs Voltage Rule, or KVL, explains that "the overall voltage throughout the circuit in any closed loop network is equal to the sum of all voltage decreases inside the same loop" which is equivalent to zero. In other words, the mathematical sum of all within the loop voltages must be equal to zero.

Two containers have a substantial amount of the air evacuated out of them so that the pressure inside is half the pressure at se

adoni [48]

Answer:

$(a)\ F_{No} = [P_{No} - \frac{P_{area}}{2}]* A$

$(b)\ F_{No} = 771.125N$

Explanation:

Given

$d_D = 6000ft$ ---- Altitude of container in Denver

$A = 0.0155m^2$ -- Surface Area of the container lid

$P_D = 79000Pa$ --- Air pressure in Denver

$P_{No} = 100250Pa$ --- Air pressure in New Orleans

<em>See comment for complete question</em>

Solving (a): The expression for $F_{No$

Force is calculated as:

$F = \triangle P * A$

The force in New Orleans is:

$F_{No} = \triangle P * A$

Since the inside pressure is half the pressure at sea level, then:

$\triangle P = P_{No} - \frac{P_{area}}{2}$

Where

$P_{area} = 101000Pa$ --- Standard Pressure

Recall that:

$F_{No} = \triangle P * A$

This gives:

$F_{No} = [P_{No} - \frac{P_{area}}{2}]* A$

Solving (b): The value of $F_{No$

In (a), we have:

$F_{No} = [P_{No} - \frac{P_{area}}{2}]* A$

Where

$A = 0.0155m^2$

$P_{No} = 100250Pa$

$P_{area} = 101000Pa$

So, we have:

$F_{No} = [100250 - \frac{101000}{2}] * 0.0155$

$F_{No} = [100250 - 50500] * 0.0155$

$F_{No} = 49750* 0.0155$

$F_{No} = 771.125N$
