Answer:
<h2>The scientist is observing an intensive property of a superconductor.</h2>
Explanation:
This is the answer because no matter how much of the superconductor material is present the resistance of the superconducting material still drops to zero when the material is cooled to very low temperatures
The average annual precipitation has been calculated by dividing the sum of average rainfall to the number of years. Thus, the given statement is true.
Precipitation has been given as the amount of water in the atmosphere that has been to fall off on the earth.
<h3 /><h3>Average Annual Precipitation</h3>
The average has been defined as the mid-value for the number readings. The average precipitation has been the approximate fall of water on the earth in the specified period.
The average annual precipitation has been calculated with the ratio of the sum of the average rainfall in the number of years to the total number of years. Thus, the given statement is true.

Answer:
I'm assuming you mean how many atoms total and not mass or anything, so it seems there are 27 atoms altogether. Unless you meant to capitalize the o in (Po4) then it would be 28 atoms.
Answer:
The correct option is b. false
Explanation:
The distance between the nucleus of an atom and it's outermost shell is called is atomic radius. The atomic radius of an Iron atom (Fe) is 0.126 nm or 1.26 angstrom. The distance between the nuclei of two Iron atoms will be 1.26 × 2 = 2.52 angstroms.
Since 2.52 angstroms is lower than 4 angstroms, the correct option is false
