Answer: A.The moon doesn’t have an atmosphere to burn up the rocks before hitting the surface.
Explanation:
Unlike the Earth, the Moon does not have an atmosphere, this leads to at least to facts:
1) Since the atmosphere (in the case of Earth) is mainly composed of gases (including oxigen) that can make combustion; when a meteor enters in the atmosphere and gets in contact with oxigen it becomes flamable and part of it is burned and separated. Then, if the meteor was large enough, the parts that were not separated will impact on the Earth Surface.
In the Moon, meteors completely impact the surface.
2) In our planet, after the meteorite impact, the crater formed will gradually fade due to erosion caused by the atmosphere. In the case of the Moon, the craters remain intact, since there is not erosion on its surface.
Answer:
D) the bending of a wave as it moves around an obstacle or passes through a narrow opening
Explanation:
Even though light travels in straight line, it will bend around objects if their size is comparative to its wavelength. This phenomenon is called diffraction.
Light will also bend if the light travels from one medium to another medium at an angle, but that is called refraction.
Diffraction occurs in one medium. Refraction occurs when light travels from one medium to another.
In physics, weight is a measure of the force exerted by gravity on a mass.
You probably know that you weigh less on the Moon than on Earth. For instance, if you weigh 100. pounds on Earth, you will weigh 16.6 pounds on the Moon. But, if your mass on Earth is 100 kg, your mass on the Moon is... also 100 kg. Because the amount of matter you have does not change from the Earth to the Moon, but the gravitational force on the Earth is stronger than on the Moon, so you weigh more on Earth.
You can think of gravity pulling a mass toward the center of an object like the Earth. It pulls a lot harder for more massive objects like the Earth than for the Moon. That's why there's a difference in weight.
As a caveat, adding energy or mass to an object will affect its mass. Additionally, general relativity informs us that when something as traveling very near the speed of light, the whole idea of mass equivalency is not exactly true...
