How long does the eclipse of an earth-like planet in a 1 au orbit take? how much time passes between eclipses?

Answers

Answer 1
1) For a moon orbiting a gas giant which is in turn orbiting a star, I want to know how long the eclipse would last for an observer standing on the moon when the planet passes between the moon and the star.

The actual values I intend to use in the end are likely to vary from these, somewhat, but I like simplicity so here's the parameters for this simplified version:

The star = our Sun.

The planet = Jupiter radius, orbits the star at a distance of 1 AU (Earth's distance from the Sun) giving it an orbital year equivalent to an Earth year (or close enough to be a negligible difference, for simplicity)

The moon = orbits the planet at a distance of 4 million KM, which should give it an orbital time around the planet of about 42 days. It is not tidally locked and rotates on its axis at a rate that will make the same point on the surface face the star exactly once every 24 hours (again, for simplicity)

For simplicity (seeing the trend here?), assume all orbits and equators of all 3 bodies share a plane, and are circular, no eccentric or inclined orbits or tilted axes, etc., and the observer is standing on a point on the equator of the moon. Assume the eclipse "starts" when the star is directly over head (noon) of the observer, and the observer says in the same location until the eclipse ends.

Please let me know if I left out any necessary variables, I probably have them available and just forgot to include them or didn't realize they were necessary.
Answer 2

The moon orbits the planet at a distance of 4 million kilometers, giving it an orbital duration of around 42 days. It is not tidally locked and rotates on its axis at a rate that causes the same place on its surface to face the star once every 24 hours (again, for simplicity)

What is the distance?

Distance is a numerical or qualitative measurement of the distance between two objects or places. The distance can refer to a physical length or an estimate based on other criteria in physics or common usage (e.g., “two counties over”). Because spatial cognition is a rich source of conceptual analogies in human thought

.The moon orbits the planet at a distance of 4 million kilometers, with an orbital period of around 42 days. It is not tidally locked and rotates on its axis at such a rate that the same spot on its surface faces the star once every 24 hours (again, for simplicity)

Therefore, The moon orbits the planet at a distance of 4 million kilometers, giving it an orbital duration of around 42 days

How does flooding rice fields reduce the need for herbicides and pesticides in rice farming? a. while rice has a submerged growth state, most weeds and pests do not. b. flooding the fields causes the soil to degrade so weeds cannot take root. c. residual herbicides and pesticides from previous seasons dissolve in the water. d. all of the above please select the best answer from the choices provided a b c d

Answers

The Correct Answer : Flooding the fields causes the soil to degrade so weeds cannot take root.

Rice has a submerged growth state while most weeds do not. Therefore, flooding rice fields reduces the growth of these less robust pests without negatively affecting the rice crop. Flooding the fields also deters many kinds of vermin that would otherwise live in the soil and harm the rice plants because they cannot breathe underwater.

What is Pesticides?

Pesticides are chemicals that may be used to kill fungus, bacteria, insects, plant diseases, snails, slugs, or weeds among others. These chemicals can work by ingestion or by touch and death may occur immediately or over a long period of time.

What is Herbicides?

Herbicides are used to kill undesirable plants or “weeds”. Some herbicides will kill all the plants they touch, while others are designed to target one species.

Therefore, we can conclude that the correct option is B.

Identify the various levels of atmosphere. troposphere mesosphere exosphere stratosphere thermosphere

Answers

The earth’s atmosphere consists of five layers. These layers are exosphere, thermosphere, mesosphere, stratosphere and troposphere.

What do you know about the different layers of the atmosphere? Troposphere:  is the lowest layer of the atmosphere and it extends up to 10km above the sea level. It starts from the ground level. The uppermost layer of the troposphere is the tropopause and the lowest layer is called the boundary layer. It contains 75% of all air present in the atmosphere. Stratosphere:  it lies above the troposphere. It extends up to 50km above the ground. The ozone layer is present in the stratosphere which protects us from the UV rays of the sun. Mesosphere:  it lies just above the stratosphere. The height of the mesosphere is around 85 km above the ground. The temperature gets really cold in this layer. Thermosphere: in this layer the temperature starts to increase again. It lies above the mesosphere and the satellites orbit the planet earth in this layer. Exosphere: The final layer of the earth’s atmosphere is the exosphere. The air from earth leaks a bit in the exosphere and this is where the earth’s atmosphere meets the space.

What would happen if water infultrated to the depths of the clay lens at point a:______.

Answers

Infiltration would happen if water infultrated to the depths of the clay lens at point .

Cavitation is the movement of water through the soil. Eventually, as water seeps into the deeper layers of the soil, it reaches aquifers, i.e. water below the surface. The upper surface of this aquifer is called the "groundwater".

Infiltration occurs when water seeps into the ground from the ground. It moves underground and moves between soil and rock. Part of the water will be absorbed by the roots to help the plant grow. The leaves of the plant will eventually release water into the air through the plant and out as waste.

The process by which water seeps into the ground to become groundwater is called groundwater recharge. The area on the surface where water infiltrates is called the recharge area. Groundwater can be recharged by rain in a number of ways: Rain seeps into where it falls and recharges aquifers from groundwater.

The Rate of movement of the Pacific Plate will be 37.87cm per year.

Underneath the Pacific Ocean is an oceanic tectonic plate known as the Pacific Plate. It is the largest tectonic plate at 103 million km2. The Farallon, Phoenix, and Izanagi Plate triple junction are where the plate initially formed 190 million years ago.

From the information given, the following can be deduced:

Distance = 500 km = 50000000cm

Time = 1.32 million years = 1320000 years.

Which stage in thunderstorm formation is characterized by updrafts accompanied by downdrafts induced by falling precipitation?.

Answers

The stage of thunderstorm formation which is characterized by updrafts accompanied by downdrafts induced by falling precipitation is called "mature stage."

What is thunderstorm?

Thunderstorms are ferocious, brief meteorological disturbances that are nearly always accompanied by lightning, thunder, thick clouds, significant amounts of rain or hail, with strong gusts of wind.

Some characteristics of thunderstorm are-

Layers of warmer, moist air travel in a strong updraft to cooler areas of the atmosphere, whereupon thunderstorms form. At that location, the updraft's moisture condenses to create imposing cumulus clouds and, subsequently, precipitation. Cooled air columns then descend to the ground and are met by powerful downpours and horizontal winds. In parallel, electrical charges build up on cloud molecules (water droplets with ice). When the electric charge that has collected is sufficiently high, lightning discharges happen. When lightning strikes, it instantly and intensely warms the surrounding air, creating shock waves that sound like thunderclaps and rolls. Occasionally, air vortices that are spinning and powerful enough just to create tornadoes are present with intense thunderstorms.
