Answer:
Perfectly inelastic collision
Explanation:
There are two types of collision.
1. Elastic collision : When the momentum of the system and the kinetic energy of the system is conserved, the collision is said to be elastic. For example, the collision of two atoms or molecules are considered to be elastic collision.
2. Inelastic collision: When the momentum the system is conserved but the kinetic energy is not conserved, the collision is said to be inelastic. For example, collision of a ball with the mud.
For a perfectly elastic collision, the two bodies stick together after collision.
Here, the meteorite collide with the Mars and buried inside it, the collision is said to be perfectly inelastic. here the kinetic energy of a body lost completely during the collision.
75 percent off of water and please water the light water and water water and then go back and please water pollution please 880m
Answer:
The speed is equals to 22.49 m/s
Explanation:
Given Data:

Required:
Speed of Traverse wave = c =?
Solution:
As we know that

Now the equation for speed of traverse wave is calculated through:

=
Substituting the values

=22.49 m/s
Explanation:
According to Dalton's atomic theory, all the atoms are individual, all the atoms of the same element are identical in properties and mass, the compound is formed from two or more kinds of the atoms, all the matter is made up of small atoms and the chemical reaction is a rearrangement of the atoms.
The discoveries which contradicts the components of Dalton's atomic theory from the given discoveries are:
Nuclear reactions can change an atom of one element into an atom of another element.
Atoms of a given element can have different numbers of neutrons.
Atoms contain smaller particles: protons, neutrons, and electrons.
Answer:
An insulator holds charge within its atomic structure. Objects with like charges repel each other, while those with unlike charges attract each other. A conducting object is said to be grounded if it is connected to the Earth through a conductor.
