All you have to do is explain the relationship between years and inches. The most rain was in 2004 with 10 inches and the least was in 1998 with 4 inches. In recent years there has been more rain than in the past. For the analysis just summarize that.
Copper has a FCC i.e. face centered cubic crystal structure. The 100 plane is essentially a planar section of the cubic cell where 4 Cu atoms occupy the 4 corners of the plane along with 1 Cu atom at the center of that plane. Each of the Cu atoms in the corners is shared by 4 adjacent unit cells. Thus, there are 2 Cu atoms present in the 100 plane (4*1/4 + 1 = 2).
Now, the planar density PD along the 100 plane is given as:
PD(100) = # atoms in the 100 plane/Area of 100 plane
= 
Here R = radius = 0.128 nm = 
PD = 
Answer:
Why some elements are radioactive (unstable). When the atoms of an element have extra neutrons or protons it creates extra energy in the nucleus and causes the atom to become unbalanced or unstable. Whether radioactive elements can become stable and if so, how. The unstable nucleus of radioactive atoms emit radiation.

Answer:
Conductors
Explanation:
Metals that are conductors let electric currents flow freely. Insulators have a resistance of a charge to flow through them.
