<span>The military is able to see in complete darkness using infrared night vision googles. They have the ability to see in low light conditions. The most popular night vision goggle format is AN/PVS7 used for the US military and in other demanding environments all over the world.</span>
Well, just for fun, let's see hat the form of the limit is
<span>v = dx/dt = b + 3 c t^2 </span>
<span>= 1.5 + 1.92 t^2 </span>
<span>========================= </span>
<span>now </span>
<span>from 1 to 3 </span>
<span>x(3)= 1.5*3 +.64*27=4.5+17.28 </span>
<span>= 21.78 </span>
<span>x(1) = 1.5+.64 = 2.14 </span>
<span>so </span>
<span>x(3)-x(1) = 19.64 </span>
<span>delta t = 3 - 1 = 2 seconds </span>
<span>so </span>
<span>v during interval = 19.64/2 </span>
<span>= 9.82 m/s </span>
<span>now check that with calculus v in the middle of that range </span>
<span>v(2) =1.5+ 1.92 (4) = 9.18 m/s </span>
<span>that makes sense, the parabola is headed up so the instant speed i the middle should be a bit less than average. </span>
Answer:
because the electricity always looking for a way to get to the ground
Answer:
The greater the luminosity of a star, the longer its period of oscillation.
Answer:
Option D.
A fan is turned from high speed to low speed.
Explanation:
It is important to note that air is also a fluid.
In a system, static pressure of air increases with the speed of rotation of the fan. This is because when the speed of the fan is increased, the force with which it is pushing the air molecules is increased. Since pressure is a relationship between force and area, the pressure of the air molecules will be increased.
Conversely, when the speed of the fan is reduced, the priming force on the air molecules will be reduced, hence the pressure of the air will drop.
This makes option D the correct option
