It depends if your talking about science or math but It could be both if it says something about weathering which is what causes a rock to break it might be chemical ill comment and tell you the correct answer
Number protons is what determines the element.
16 protons determines that the substance is sulphur.
The number of neutrons can vary according to the isotope. The mass number is the total count of neutrons and protons, so sulphur with a mass number of 34 has 34-16=18 neutrons.
32.065 is the weighted average of the atomic weights of different isotopes, so does not apply to a single isotope.
We see that colour which is reflected by the surface because the object is made up of that colour.
<h3>What is the colour of lemon in white light?</h3>
A lemon in white light appears yellow to the human eye because yellow light is reflected by the lemon's surface while all other wavelengths of light are absorbed.
If the same lemon is placed into red light. It will appear to look red. This occurs because the red light will be transmitted by the lemon's surface and red light will be reflected to your eye.
So we can conclude that we see that colour which is reflected by the surface because the object is made up of that colour.

When we can get the Kinetic energy from this formula KE= 1/2 M V^2
and we can get the potential energy from this formula PE = M g H
we can set that the kinetic energy at the bottom of the fall equals the potential energy at the top so,
KE = PE
1/2 MV^2 = M g H
1/2 V^2 = g H
when V is the velocity, g is an acceleration of gravitational force and H is the height of the fall.
∴ v^2 = 2 * 9.8 * 8 = 156.8
∴ v= √156.8 = 12.5 m/s
