Answer:
See the explanation below
Explanation:
There are several measures for the international system of measures. Let's name some and their representation symbol.
meter = [m]
time = [s] = seconds
mass = [kg] = kilograms
Temperature = [°C] = celcius degrees
Power = [W] = watts.
Force = [N] = Newtons
Answer:
Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. A common example is oil and water. Oil contains molecules that are non-polar, thus they do not dissolve in water.
Explanation:
The masses amount of a proton and neutron are 1.0087 and 1.0073 amu respectively.
<h3>What is a Proton?</h3>
This is defined as sub atomic particle which is positively charged and is present in the nucleus while the neutron is also a particle present in the nucleus but has a neutral charge.
Electrons on the other hand are found outside the nucleus and are negatively charged. It is the sub atomic particle which is actively involved in a chemical reaction.
The masses of neutron and proton are 1.0087 and 1.0073 amu respectively and was discovered by scientists thereby making it the most appropriate choice.

The correct statements are:
B. a small rock sitting on top of a big rock
As the rock is at a height with respect to ground it has potential Energy
and
C. a stretched rubber band
A stretched rubber band has elastic potential energy
The others are actually moving and hence would consist of Kinetic energy. Potential energy is stored in objects that do not move and are stationary.
