Optical astronomers need a clear, dark sky to collect good data. Explain why radio astronomers have no problem observing in the

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.

Match each method of erosion with the correct definition
Katena32 [7]
In this item, we are asked to determine the correct definition for the terms. It is unfortunate that they meanings to which we could match them are not given. With that, the answers written here are the well-researched ones.

Solution --> This type of erosion happens when the components found in the rocks (i.e. limestone) are dissolved through the acid components of acid rain.

Abrasion --> This is a process by which the rocks that are eroded to the riverbanks wear down other components of the bed.

Saltation --> This process involves the movement of the particles through a series of bounces that are short and are along the surface of the ground. This results to dislodging the other particles.

Explain how the graphic organizer helped you formulate your decision and participate in the discussion.
nekit [7.7K]

Answer:

The graphic organizers help to keep track of the details. They are a visual representation of knowledge that rescue the important aspects of a concept using labels within a scheme. They also present information in a concise manner, highlighting the organization and the relationship of the concepts. Graphic organizers help students organize their thinking process and their writing.

A rookie quarterback throws a football with an initial upward velocity component of 17.0 m/s and a horizontal velocity component
vitfil [10]

Answer:

(a) 1.73 s

(b) 14.75 m

(c) 3.36 s

(d) double

(e) 63.32 m

Explanation:

Vertical component of initial velocity, uy = 17 m/s

Horizontal component of initial velocity, ux = 18.3 m/s

(A) At highest point of trajectory, the vertical component of velocity is zero. Let the time taken is t.

Use first equation of motion in vertical direction

vy = uy - gt

0 = 17 - 9.8 t

t = 1.73 seconds

(B) Let the highest point is at height h.

Use III equation of motion in vertical direction

v^{2}=u^{2}-2gh

0 = 17 x 17 - 2 x 9.8 x h

h = 14.75 m

(C) The time taken by the ball to return to original level is T.

Use second equation of motion i vertical direction.

h = ut + 0.5at^2

h = 0 , u = 17 m/s

0 = 17 t - 0.5 x 9.8 t^2

t = 3.46 second

(D) It is the double of time calculated in part A

(E) Horizontal distance = horizontal velocity x total time

d = 18.3 x 3.46 = 63.32 m
