Due to the Composition, different asteroids reflect different percentages of the light falling on them.
What are Asteroids:
- Asteroids are small, rocky objects that orbit the Sun. Although asteroids orbit the Sun like planets, they are much smaller than planets.
- Asteroids are generally made up of rocky material, metals and their size are large in comparison to comets. Asteroid belt is found between Jupiter and Mars.
Composition of Asteroids:
- Most of the asteroids in the Main Belt are made of rock and stone.
- The remaining asteroids are made up of a mix of these, along with carbon-rich materials. Some of the more distant asteroids tend to contain more ices.
We determine reflectivity of asteroids by comparing the brightness of light in the visible spectrum to the brightness of light in the infrared spectrum. The light shining from asteroids is reflected sunlight.
Hence we can say that,
Due to the Composition, different asteroids reflect different percentages of the light falling on them.

in which standard you are, i am typing your answer till please reply.
Answer:
Less gravity and Vacuum
Explanation:
As per the laws of gravity, acceleration due to gravity is independent of mass of an object. That means if you drop two objects of different mass form same height with zero initial speed, they will reach the ground at the same time.
Galileo had given this theory and proved it. But when you take one object as feather the presence of air makes it float and the law seems to fail. The law is correct but the only reason it fails is because the feather starts floating in the air.
To prove this we need a vacuum chamber with a great height to witness the free fall condition. Creating such a chamber on Earth is very difficult. David Scott had these advantages on the Moon. As Moon doesn't have any atmosphere so he got a natural vacuum environment.
Also, as the acceleration due to gravity on Moon is of that on the Earth, it will take less time to touch the surface and one can easily observe the free fall without any aid of high speed camera.
Answer:
A and B.
Explanation:
Answer C is wrong - there are no tall trees underwater
Answer D is wrong, there are mountain chains underwater due to plate tectonics.
<span>The answer is none. According to the first law of Newton, an object stays at the same speed in the same direction if there are not forces unbalancing the object. Without friction, the car would be moving forever, unless there is another force accelerating or stopping the car.</span>
