Answer:
<h3>Yes</h3>
Explanation:
If you build thing "a" and thing "a" builds thing "b" you <u>indirectly</u> build thing "b".
Answer:
The instantaneous axis of rotation=
x = 0 ; z = 8.4 ft
Explanation:
Given:
Speed of helicopter, Vo= 120 mi/h, converting to ft/sec, we have:
= 176 ft/s
Angular velociyy, w = 220 rpm, converting to rad/sec, we have: 
The helicopter moves horizontally in the x direction at a speed of 120 mi/h, this means that the helicopter moves in the positive x direction at 120mi/h
To find the instantaneous axis of rotation of the main blades, we have:
Where Vc = 20.95 rad/s
Vo = 176 ft/s
= 8.4 ft
Therefore the axis of rotation=
x = 0 ; z = 8.4 ft

Answer:
Under no circumstances
Explanation:
I'm not 100% sure why, but I remember hearing that you're not suposed to go over the speed limit no matter what
The initial void ratio is the <em>parameter </em>which is used to show the structural foundations for each <em>specimen of sand </em>so that the method and speed of compression would be <em>measured</em>.
Relative density is the mass per unit volume of each specimen of sand which is <em>measured </em>and it has to do with the<em> relative ratio</em> of the density of the sand.
Unit weight is the the exact weight per cubic foot of the sand which is measured.
Please note that your question is incomplete so I gave you a general overview to help you better understand the concept
