Q = 1/2 nv2

SAT
1 answer:
ArbitrLikvidat [17]4 years ago
6 0

Answer:

<em>2.25 or 9/4.</em>

Explanation:

To solve this problem, you need to set up to equations with variables. Let q1 be the dynamic pressure of the slower fluid moving with velocity v1, and let q2 be the dynamic pressure of the faster fluid moving with velocity v2. Then,

v2 = 1.5v1

Given the equation q =  1 /2

nv2, substituting the dynamic pressure and velocity of the faster fluid gives q2 = 1 /2  n(v2)^2. Since v2 = 1.5v1, the expression 1.5v1 can be substituted for v2 in this equation, giving q2 =  1 /2  n(1.5v1)^2. By squaring 1.5, you can rewrite the previous equation as:

q2 = (2.25)( 1 /2 ) n(v1)^2=(2.25)q1

Therefore, the ratio of the dynamic pressure of the faster fluid is

q2 /q1  =  2.25q1 /q1  = 2.25

<em>The final answer is 2.25 or 9/4.</em>

Two friends are planning for a gathering. the food budget is modeled by one half times the absolute value of the quantity x minu
Georgia [21]

The least and greatest amounts that the two friends could spend on food would be 114 and 146.

We have,

The food budget is modeled by an equation,

i.e.

\frac{1}{2} |x - 130| = 8

Here,

x = the amount spent on food

So,

Now,

According to the question,

To find the least and greatest amounts that the two friends could spend on food,

We have to,

Find absolute value of the quantity x,

i.e.

\frac{1}{2} |x - 130| = 8

We get,

|x - 130| = 16

i.e.

x - 130 = ± 16

So,

The least amount will be, when we take negative value,

i.e.

x - 130 = - 16

On solving we get,

x = 114,

NOw,

The greatest amount will be, when we take positive value,

i.e.

x - 130 =  16

On solving we get,

x = 146,

So,

The least amount is 114 and greatest amount is 146.

Hence we can say that the least and greatest amounts that the two friends could spend on food would be 114 and 146.

I need a recent example of President Trump acting as Commander in Chief
Lapatulllka [165]

Answer:

WASHINGTON — He canceled a trip to a cemetery in France where American soldiers from World War I are buried. He did not go to the observance at Arlington National Cemetery on Veterans Day. He has not visited American troops in Iraq or Afghanistan.

And shortly after becoming commander in chief, President Trump asked so few questions in a briefing at MacDill Air Force Base in Tampa, Fla., that top military commanders cut the number of prepared PowerPoint slides to three — they had initially planned 18 — said two officials with knowledge of the visit.

The commanders had slotted two hours for the meeting, but it lasted less than one.

Rhetorically, Mr. Trump has embraced the United States’ 1.3 million active-duty troops as “my military” and “my generals” and has posted on Twitter that under his leadership, the American armed forces will be “the finest that our Country has ever had.” But top Defense Department officials say that Mr. Trump has not fully grasped the role of the troops he commands, nor the responsibility that he has to lead them and protect them from politics.

“There was the belief that over time, he would better understand, but I don’t know that that’s the case,” said Col. David Lapan, a retired Marine who served in the Trump administration in 2017 as a spokesman for the Department of Homeland Security. “I don’t think that he understands the proper use and role of the military and what we can, and can’t, do.”
