A planet whose distance from the sun is 3 au would have an orbital period of how many earth-years?

Geography

<span>The orbital period will be 5.196 earth years. The period of an orbit is proportional to the square root of the cube of the semi-major axis. The semi-major axis of earth is 1 AU (actually 1.000001018 AU, but for this problem 1 is close enough). The hypothetical planet will have a semi-major axis of 3 AU. So making the ratios with earth's year being 1, earth's semi-major axis being 1, the planet's year being y, and the planet's semi-major axis being 3, we get the following ratio. 1 / 1^(3/2) = y / 3^(3/2) Raise the denominators to the 3/2 powers. 1/1 = y/5.196 Multiply both sides by 5.196 5.196 = y So the orbit period will be 5.196 earth years.</span>

What effect did the movement of glaciers have on the region? 1. caused the formation of fjords 2. created thousands of lakes 3.
insens350 [35]

Answer:

Option (1)

Explanation:

A fjord is usually defined as a contrasting geological landform, which is typically a U-shaped valley, that is formed due to the movement of the glaciers. It is generally narrow and forms steep-sided cliffs on both the sides and is mostly connected to the seas. They have huge depth, sometimes reaches up to a depth of about 1300 m. The downward flowing glaciers pushes the terminal moraine and allows it to remain underwater at its entrance, resulting in shallow water at the fjord's neck, in comparison to the main body of the fjord that is located behind it.

Thus, the correct answer is option (1).

Ranking Task: Sidereal and Synodic Periods
8_murik_8 [283]

Answer:

Sidereal Time is the shortest time of earth and Synodic time is longest time of the sun.

Explanation:

<u>shortest to the longest time. </u>

  • Sidereal day and one rotation of the earth on its axis.
  • Sidereal month and one full orbit around the earth.
  • Synodic month and one full cycle of the moon.
  • Solar day i.e Earth rotation on its axis so that the sun appears same on the sky.

As sideral refers to the events that occur on the same day with 23 hours 56 minutes 4.091 sec, and synodic day refers to the 24 hours and 2.5 ms aligned to astronomical bodies. Each synodic day the gradual motion is one degree eastwards. (360 degrees per year.)

The solar day is just one complete solar day. Time is calculated based on sun positioning of the solar clock i.e 24 hr format and the mean solar time is 12 hours.

Solar time does include the moon phases as this phenomenon is limited to the sidereal rotation of the earth on its axis. Aphelion and Perihelion are caused by the earth's rotational effects towards the sun being exposed at the time of day.
