A meteorite approaching a planet of mass M collides with an automatic space station orbiting the planet in a circular trajectory
Jet001 [13]
We are given with
M = mass of planet
R = radius of circular trajectory of the satellite
ms = mass of the station
mm = mass of the meteorite
ms = 10 mm
R/2 = new orbit distance

The speed of the meteorite can be solved using the law of conservation of momentum
ms vs + mm vm = (ms + mm) v
Since the new orbit distance is half the original
v = 2 vs

Substitute and solve for vs

Which of the following are the result of developments in science ?
jasenka [17]

Hello!

Your answer is all of the above. Science is a very broad field, and it is the thing which has engineered most, if not all, of our technology today. Take for example microwave ovens. These could not have been possible without science, as it was science that realized that "microwaves" (a type of wave length) even existed.

Hope this helps!

What records the difference between still air and air that is being rammed into the system?
Alex Ar [27]

Answer:

Still air is at atmospheric pressure and atmospheric temperature whereas rammed air has a higher pressure, higher density than the atmosphere and as a result, its temperature also increases.

Explanation:

  • Still air is at atmospheric pressure and atmospheric temperature whereas rammed air has a higher pressure than the atmosphere and as a result, its temperature also increases.
  • Rammed air is under pressure and has a higher density. Rammed air has a greater mass in less volume.
  • The rammed air is used in compressors and gas turbines to produce energy in the desired form.
