A hammer pounding a nail into a board is an example of Newton’s Third law.
Newton’s third law states that for every action there is an equal and opposite reaction. Meaning, when you hit the hammer on the board the same amount of energy that is going into the board, is going into the hammer. Causing the hammer to bounce off the board.

Answer:
Explanation:
The De Broglie's wavelength of an object is given by:
where
h is the Planck constant
m is the mass of the object
v is the speed of the object
In this problem, we have:
is the mass of the pellet
is the speed of the pellet
Substituting into the equation, we find the wavelength of the pellet:
The correct answer is letter C, regular reflection.
<span>An image seen in a smooth dinner plate is an example of a
regular reflection. This phenomenon only occurs in smooth and polished surfaces.
During this stage light occurs at a certain angle and is reflected back at the
same angle producing reflections in a way like a mirror does this commonly.</span>
By how many neutrons are in the atom
Here, We know, Density = Mass / Volume
Here, mass = 249.8 g
volume = 92.5 cm³
Substitute their values,
d = 249.8 / 92.5
d = 2.7 g/cm³
In short, Your Answer would be "Aluminum"
