UK where it is often very cloudy.

Answer:

In the clarification portion elsewhere here, the definition of the concern is mentioned.

Explanation:

So like optical telescopes capture light waves, introduce it to concentrate, enhance it, as well as make it usable through different instruments via study, so radio telescopes accumulate weak signal light waves, introduce that one to focus, enhance it, as well as make this information available during research. To research naturally produced radio illumination from stars, galaxies, dark matter, as well as other natural phenomena, we utilize telescopes.

Optical telescopes detect space-borne visible light. There are some drawbacks of optical telescopes mostly on the surface:

  • Mostly at night would they have been seen.
  • Unless the weather gets cloudy, bad, or gloomy, they shouldn't be seen.

Although radio telescopes monitor space-coming radio waves. Those other telescopes, when they are already typically very massive as well as costly, have such an improvement surrounded by optical telescopes. They should be included in poor weather and, when they travel through the surrounding air, the radio waves aren't obscured by clouds. Throughout the afternoon and also some at night, radio telescopes are sometimes used.

When an automobile moves with constant speed down a highway, most of the power developed by the engine is used to compensate for
GaryK [48]

Answer:

F=4945.7N

Explanation:

Most of the power developed by the engine is used to compensate for the mechanical energy loss due to frictional forces because these are the only forces on the horizontal direction the automobile is subjected to, besides of that generated by the engine itself. If the automobile is moving at constant speed, then these the force the engine provides is equal to the total friction force acting on the car.

We calculate then the force the engine provides. We know that power relates to work by the equation P=\frac{W}{t}, and that work relates to force by the equation W=Fd, so combining them we have:

P=\frac{Fd}{t}=Fv

Which can be written as:

F=\frac{P}{v}

And since 179hp are 179hp(\frac{746W}{1hp})=133534W, for our values the force the engine provides is:

F=\frac{133534W}{27m/s}=4945.7N

Which is also then the total friction force acting on the car.
