TLDR: The kinetic energy is determined to be zero.
Kinetic energy is energy of motion; when an object is moving (i.e. it has speed or velocity), it has some amount of kinetic energy. The equation itself looks like so:
KE=1/2(m)(v)^2,
where "m" represents the mass of the object and "v" represents the objects speed or velocity. In this example, the ball has stopped, meaning it has no speed/velocity. This means that the final kinetic energy is determined to be zero or none, due to the lack of motion. Mathematically, you can see this by substituting "0" in for "v" (the ball is stopped):
KE=1/2(m)(v)^2
KE=1/2(m)(0)^2
KE=1/2(m)*0
KE=1/2*0
KE=0 J,
or zero kinetic energy.
Hope this helps! :)
The principal thing that one can read from a periodic table is the atomic number which is the number in the box that the element symbol appears and it means the number of protons in the nucleus of its atom and this number determines its chemical properties and is unique for each chemical element. The table is color coded to show the different types of elements ie "transition metals, alkali metals, noble gases" etc. and these different types are grouped together.
Answer:
The first claim is false. Natural resources can most definitely exist without synthetic products.
Explanation:
All synthetic products are derived from natural resources as everything has to come from a source in the beginning. However, most natural resources themselves are the source, make sense? For example, water is a naturally occurring resource, but even water is derived from specific components, however it doesn't need anything synthetic to exist. Now take hairspray, to make hairspray you need water and synthetic resources, see where I'm going with that?
Answer:
Explanation:
No atoms of Mg have a mass of 24.3050 u. That is the average mass of all the isotopes of Mg.
However, the most common isotope of Mg is ₁₂²⁴Mg (mass = 23.99 u)
The atomic number of Mg is 12. It has 12 protons.
The atomic mass of ²⁴Mg is 24. That's the total number of protons and neutrons.
p + n = 24
12 + n = 24
n = 12
An atom of ²⁴Mg has 12 neutrons.
If the atom is neutral, the number of electrons equals the number of protons.
e = p = 12
