Is this correct guys?

The correct descriptions that help to define luminosity are How much energy is emitted per second, How much surface area the object has, and The amount of brightness of an object.

An object's luminosity, which is the quantity of energy it emits over a predetermined period, is a measurement of its inherent brightness. Since it simply measures the object's power output, it can be expressed in units like Watts.

A star's luminosity, or the total amount of energy it emits each second, is determined by two factors: The stellar photosphere's "Effective Temperature," T. the star's total surface area, which is influenced by its radius, R.

The size, temperature, and distance of a star are the three variables that determine how bright it seems to us on Earth. The brilliance of a star is measured by its magnitude.

Answer:

Without oceans and land (hydrosphere and geosphere), there would be no wind (as winds are produced by differences of air temperature between the land and oceans). This rock cutting shows the rocks that have formed on the surface of the Earth. Last of all, without the geosphere, there would be no world to live on!

Answer:

Surface currents affect climate by moving cold and warm water around the globe. In general, currents carry warm water from the tropics toward the poles and bring cold water back toward the equator. A surface current warms or cools the air above it, influencing the climate of the land near the coast.

The one with one parent and five offspring represents asexual reproduction. Asexual reproduction only requires one parent, so the offspring are genetically identical to the parent. The advantage is that organisms can reproduce much quicker using this method.

The organizer with two parents and one offspring represents sexual reproduction. Again, sexual reproduction requires two parents.

B. Consisting of billions of galaxies

Hope this helps :)

Answer:

The correct answer is - 0 m/s.

Explanation:

In this position-time graph or distance-time graph, there are three different part that shows three different velocities one in increasing as it moves from a lower position in relative to time and one is stationary and the third is decreasing.

'Straight lines' on a distance-time graph suggest that the movement of the object is constant. During 'Part B' of the journey the object travels 0m in 3s. It is stationary for 3 seconds so the velocity will be zero as well.
