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>

Select the statements below that are true for the aviation combat element of a MAGTF. Select all that apply.

GaryK [48]

The statements that are true for the aviation combat element of a MAGTF are:

The aviation combat element is usually composed of an aviation unit headquarters and various other aviation units or their detachments.
It can vary in size from a small aviation detachment of specifically required aircraft to one or more Marine aircraft wings.

<h3>What is Aviation?</h3>

This refers to the movement of goods, people, and weapons from one location to another, through aircraft.

Hence, we can see that based on the given description of the functions of the MAGTF, we can see that they are in overall control of the aviation combat elements and they have a unit headquarters and detachments.
