Answer: The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons. The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.

Answer:
Physics is the answer to all the forces in nature and it is important to know all of that in a day to day life to succeed in life
Explanation:
<span><span>To create a concept map for waves, you need to mention the different types of waves. Mechanical and EM waves are two examples. Mechanical waves
transfer mechanical energy and require a medium. EM waves transfer EM energy
but do not require a medium – they can pass through a vacuum. </span>Both types of waves have different speeds
transferring through different mediums.</span>
Other things that may be mentioned in the map include law of
reflection, idea of diffraction, standing waves and so on.
The work that need to do is 66.24 J.
<h3>Explanation :</h3>
Hello guys, before we can count how much the work that needed to pull the toy, we should know how formula to count it first. Because the movement is with the angle, so the formula is :
If :
- W = work (J)
- F = force (N)
- s = shift (m)
- θ = elevation angle (°)
We know that :
- x = the horizontal shift = 9,2 m
- θ = elevation angle = 15°
W = work = ... J
So, the work that need to do is 66.24 J.
