Mass<span> is the amount of matter in an object. Move to a different planet and an object's weight will change, but its </span>mass<span> will be the same. </span>
Answer:
Answer is A
Explanation:
Now we know that an atom wants to complete its outer shell while keeping electrons in pairs of two now in A there are four electrons which which can be ejected while in B will want to accept 3 electrons to complete its shell as ejecting five will take lot of energy similar case will be for C,D and E which would want to accept 2,1,0 electrons respectively
The enamel is the strongest substance in our bodies mainly inside your mouth.
In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.
According to the kinetic theory of matter, the molecules that compose matter are in constant random motion. The nature of this motion varies in the three states of matter which are;
In the solid state, the molecules do not translate, they only vibrate and rotate about their mean positions. In the liquids state, the molecules translate but they still have restricted degrees of freedom due to intermolecular interactions. In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.

Answer:
Much younger than Earth
Explanation:
The moon is believed to be much more younger than the earth.
The moon is earth's only natural satellite.
It is hypothesised that a planetary body as big as Mars collided with earth. The impact causes vapourization and hauling of materials from the earth crust and mantle.
The blasted particles and the matter were pulled together by gravity. These ones formed our satellite, the moon.
Some of the matter fell back to the earth surface.
The moon was formed after earth was formed and it is much younger than our blue planet.
