Because light is degraded when it has to pass through air.

The best places for large telescopes would be on the Moon, in space,
or in orbit (like the Hubble, Kepler, and Webb space telescopes). 

If you can't manage any of those places, or can't afford them, then
the next best choice for a location is any place where the light doesn't
need to plow through a lot of air to reach your telescope.  Those places
are either on top of mountains or under giant helium balloons.  Both of
these ideas have been used extensively for the past 100 years.

_____ refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.
german

Answer:

Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.

Explanation:

Sensation helps us to detect changes in our physical environment.

Sensation occurs in three steps,

  • Sensory receptors, these detect stimuli.
  • Sensory stimuli are converted into electrical impulses to be decoded by the brain.
  • Finally, electrical impulses move along neural pathways to specific parts of the brain wherein the impulses are decoded into useful information.

Therefore, Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.

A 1325 kg car and a 2050 kg pickup truck approach a curve on a highway that has a radius of 255 m. At what angle should the high
Scorpion4ik [409]

Answer:

the banking angle of the road is 24.2⁰

Explanation:

Given;

speed of the vehicles considered, v = 75 mi/h

Speed in m/s ⇒ 1 mi/h --------> 0.44704 m/s

                         75 mi/h --------> ?

=   75 x 0.44704 m/s = 33.528 m/s

radius of the curve, r = 255 m

The banking angle of the road is calculated as;

\theta = tan^{-1} (\frac{v^2}{rg} )\\\\\theta = tan^{-1} (\frac{33.528^2}{255\times 9.8} )\\\\\theta  = tan^{-1}(0.44983)\\\\\theta  =24.2^0

Therefore, the banking angle of the road is 24.2⁰
