Explanation:
<h2>Right answer: a number and a unit</h2>
The measurement consists in <em>comparing a selected pattern with the object or phenomenon whose physical magnitude is going to be measured, to find out how many times the pattern is contained in that magnitude.</em> That is, it is about identifying or quantifying a particular characteristic or aspect of a particular object or construct.
Now, a well done measurement has two parts:
-The number gives us information about the quantity of the measurement, or in other words, the magnitude of the measurement and its precision.
-The units gives us information about the property that is being measured. This is quite important, because a measurement or result with no units is useless.
Note the units may be expressed with letter or symbols, depending on what we are measuring.
Why would we assume that Earth is the center of the the Universe in the first place?
Besides the fact the Earth contains life, it is no different from any other planet that we have ever seen, nor is the solar system in which it resides. There is no reason in the first place to assume its placement in the universe is different either.
The percentage of the iceberg that is visible above the water's surface will be 11.5%.
<h3>What is density?</h3>
Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.
The mass and density relation is given as
mass = density × volume
Density of ice = 917 kg/m³
Density of the seawater=1025 kg/m³
The ratio by which the iceberg submerge is found as;
Hence,89.5 % of the ice is submerged.
The percentage of the iceberg that is visible above the water's surface is;
⇒1-.89.5 %
⇒11.55 %
Hence, the percentage of the iceberg that is visible above the water's surface will be 11.5%.
