Which of the following statements about pitot-static systems is FALSE? a). A pitot probe measures the Total Pressure of the free

Pavlova-9 [17]

Answer:

C

Explanation:

Pitot tube:

Pitot tube is a device which is used to measure the velocity of flow by measuring pressure difference between the points.

As we know that stagnation pressure is the summation of dynamic and static pressure.

Stagnation pressure = Static pressure + Dynamic pressure

So

Dynamic pressure = Stagnation pressure - Static pressure

We know that dynamic pressure

$P_{dynamic}=\dfrac{\rho V^2}{2}$

On the other hand Pitot tube measure the dynamic pressure.

So option C is correct.

As resistors are added in series to a circuit, the total resistance will

The equivalent of the resistance connected in the series will be Req=R₁+R₂+R₃.

<h3>
What is resistance?</h3>

Resistance is the obstruction offered whenever the current is flowing through the circuit.

So the equivalent resistance is when three resistances are connected in series. When the resistances are connected in series then the voltage is different and the current remain same in each resistance.

V eq = V₁ + V₂ + V₃

IReq = IR₁ + IR₂ + IR₃

Req = R₁ + R₂ + R₃

Therefore the equivalent of the resistance connected in the series will be Req=R₁+R₂+R₃.

A market research survey has 15 questions and will be sent to 500 people. What is the total cost to conduct survey if it has a $

Dimas [21]

Answer:

$39,500

Explanation:

In order to find the total cost, we proceed as follows:

1)

First, the base fee is:

$b=\$1000$

2)

Then we calculate the total number of questions: we have 15 questions per survey, and a total of 500 surveys (for 500 people), therefore the total number of questions is

$Q=15\cdot 500 =7500$

Since the cost is $5 per question, the total cost of the questions is

$q=\$5\cdot 7500 =\$37,500$

3)

Finally, we have 500 persons, and there is a cost of $2 per each person, so the cost due to this is

$p=\$2\cdot 500 = \$1000$

Therefore, the total cost is:

$T=b+q+p=1000+37,500+1000=\$39,500$
