Lighting gives a sense of scale (The sky)
Answer:
Depends how it is built and what it is made of.
Explanation:
very high
Answer:
The extent of greenhouse effect on mars is 
Explanation:
From the question we are told that
The albedo value of Mars is 
The albedo value of Mars is 
The surface temperature of Mars is 
The surface temperature of Venus is 
The distance of Mars from the sun is 
The distance of Venus from sun is 
The radius of the sun is 
The energy flux is 
The solar constant for Mars is mathematically represented as
![T = [\frac{E R^2 (1- A_1)}{\sigma d_m} ]](https://tex.z-dn.net/?f=T%20%3D%20%5B%5Cfrac%7BE%20R%5E2%20%281-%20A_1%29%7D%7B%5Csigma%20d_m%7D%20%5D)
Where 
is the Stefan's constant with a value 
So substituting values
So the greenhouse effect on Mars is
Answer:
6, 3, 2, 5, 4, 1
Explanation:
Let's describe them from smallest to largest. In fact the size order is not exact as there are exceptions.
An asteroid is a rocky body which lies in the asteroid belt between Mars and Jupiter. They are typically quite small object. The largest asteroid Ceres has been reclassified as a dwarf planet.
A moon is typically a rocky body which is in orbit around a planet. Some moons such as our Moon are quite large and are typically bigger than asteroid. Some moons can actually be smaller than some asteroids.
A planet is a nearly spherical body which is in orbit around the Sun. Planets are larger than moons.
A star is what planets orbit around. It is the source of light and heat. Our Sun is a star which is many times bigger than all of the planets.
A solar system is a star and all of its planets, asteroids, comets and other bodies. It is significantly bigger than a star.
A galaxy, such as our Milky Way Galaxy, is a collection of solar systems orbiting around a central core. Most galaxies have a supermassive black hole at their centres.
Galaxies also form clusters which are large scale structures.
The universe is everything. It contains billions of galaxies.
Answer:D-velocity
Explanation:
Given
Constant linear acceleration i.e. acceleration is constant
a=constant
and we know 
Thus velocity is changing uniformly to give constant acceleration
While displacement and distance are function of time thus they are not changing uniformly.
