Answer:

True

Explanation:

The statement is true because power data centers, cell towers, base stations, recharge mobiles, and so on emit electromagnetic waves which radiate to the space and causes ozone layer depletion which are harmful to both planet and human in such that it damage the ecosystem and release of ultraviolet rays causes skin cancers in human living in the environment.

The idling engines of a landing turbojet produce forward thrust when operating in a normal manner, but they can produce reverse
sertanlavr [38]

Answer:

T = 5416.67 N

T = -2083.5 N

T = 0

Explanation:

Forward thrust has positive values and reverse thrust has negative values.

part a

Flight speed u = ( 150 km / h ) / 3.6 = 41.67 km / s

The thrust force represents the horizontal or x-component of momentum equation:

T = flow(m_{exhaust})*(u_{exhaust} - u_{flight} )\\T = (50 kg/s ) * (150 - 41.67)\\\\T = 5416.67 N

Answer: The thrust force T = 5416.67 N

part b

Now the exhaust velocity is now vertical due to reverse thrust application, then it has a zero horizontal component, thus thrust equation is:

T = flow(m_{exhaust})*(u_{exhaust} - u_{flight} )\\T = (50 kg/s ) * (0 - 41.67)\\\\T = -2083.5 N

Answer: The thrust force T = -2083.5 N reverse direction

part c

Now the exhaust velocity and flight velocity is zero, then it has a zero horizontal component, thus thrust is also zero as there is no difference in two velocities in x direction.

Answer: T = 0 N

9. An orifice tube restriction is often indicated by:
andriy [413]

Answer:

I believe 80% the answer is low gage pressure.

Explanation:

while naturally a restriction of an orifice like placing your thumb on a water hose would cause a high pressure output, however in an entire system if the proper amount of fluid is not making its way through the system then there would be inadequate system pressure. I hope my train of thought is correct though. let me know either way

How to build a robot
Anuta_ua [19.1K]
Seriously? Ok

first, get some good quality metal, preferably aluminum, if you want to avoid rust.

build in the the shape of a robot, you can use a doll to help you if you are a beginner, but feel free to shape it the a Star Wars Character!

create an AI (now you said robot not AI) and fix everything up.
