The main purpose of the turbine in the turbojet engine is to A. drive the compressor.
B. reduce the temperature of the exhaust gas.
C. increase the velocity of the exhaust gases.
D. compress the air. ~IT is NOT D.

Answers

Answer 1
Answer: The correct answer is A. drive the compressor. It's not D because the compressor compresses it, not the turbine. The temperature and the velocity of gasses are unrelated to this. There are in fact two turbines, and the first one gets power from exhaustion, which is then used to power to turbine in the turbojet that is used to drive the compressor. This is how turbojets commonly work.

The weight of an object on a planet depends not only on its mass, but also on its distance from the planets center. Uranus has more than 14 times as much mass as earth, yet the gravitational force is less. Explain how this could be. Pleas answer cause idk what it means.

Answers

The further an object is from the centre of a planet, the lower it's gravitational force. Uranus had 14 times as much mass as earth, but it's also a lot bigger than earth. So assuming an object is on the surface of Uranus, it would be really far away from the centre of Uranus, therefore the gravitational force is less.

Hope this helps!

What is the magnitude of the electric field at a point 0.0075 m from a 0.0035 C charge? 

Answers

In an electric field force,F= q₁q₂/4πε₀ r²  (coulomb's law)  as we know,F=qE  E=F/q
E=q/4πε₀ r²
here,r= 0.0075 m
       q= 0.0035 C
      1/4πε₀  = 9×10⁹
        E=  9×10⁹× 0.0035/(0.0075)²

As the wavelength of electromagnetic radiation increases _______.

Answers

The wider the waves are spread out, the longer it takes for each cycle to pass a given point. It's this—how FREQUENTLY waves pass a point—that determines the value of 'frequency'. If they are going by less frequently past that point, then the 'frequency' is less: it decreases.

Answer:

'frequency' is less: it decreases.
