The nucleus of the hydrogen atom has a radius of about
1 x 10^-15 m. The electron is normally at a distance of about 5.3 x
10^-11 m
from the nucleus. Assuming that the hydrogen atom is a sphere with
a
radius of 5.3 x 10^-11 m, find (a) the volume of the atom, (b)
the
volume of the nucleus, and (c) the percentage of the volume of
the
atom that is occupied by the nucleus.The nucleus of the hydrogen

Write a java program, creating three threads, to sort two arrays and merge them into a third array. More specifically:
Create a thread to sort the first array. Create a thread to sort the second array. Create a thread to merge the arrays into the third array. Let the main method prints the merged array.
i want three threads to be created .
You must call the two sorter threads together. In other words, if we name these threads sorta, sortb, and merge, you must call the start methods in the following sequence: sorta.start(); sortb.start(); Some java code merge.start();
I post the sequential program for this assignment. Note that you need to change the classes Sorter and Merger to make them suitable for threads.
import java.util.Random;
public class Main{
public static void main(String[] args) {
Random rand = new Random();
int size = rand.nextInt(50) + 1;
int a[] = new int[size];
size = rand.nextInt(50) + 1;
int b[] = new int[size];
for(int i = 0; i < a.length; i++)
a[i] = rand.nextInt(999);
for(int i = 0; i < b.length; i++)
b[i] = rand.nextInt(999);
new Sorter(a);
new Sorter(b);
int[] c = new int[a.length + b.length];
new Merger(a, b, c);
for(int i = 0; i < c.length; i++)
System.out.print(c[i] + " ");
}

On planet Tehar, the free-fall acceleration is the same as that on Earth, but there is also a strong downward electric field that is uniform close to the planet's surface. A 1.86-kg ball having a charge of 5.04 μC is thrown upward at a speed of20.1 m/s. It hits the ground after an interval of 4.10 s. What is the potential difference between the starting point and the top point of the trajectory? (Use 9.8 m/s2 for the acceleration due to gravity.)

Stoichiometry Problems for Reaction in Aqueous Solutions
-.The quantity of Cl– in a municipal water supply is determined by titrating the sample with Ag+. The precipitation reaction taking place during the titration is Ag(aq) + Cl(aq) ->AgCl(s)
The end point in this type of titration is marked by a change in color of a special type of indicator. (a) How many grams of chloride ion are in a sample of the water if 20.2 mL of 0.200 M Ag+ is needed to react with all the chloride in the sample? (b) If the sample has a mass of 15.0 g, what percentage of Cl– does it contain?
-.A mysterious white powder is found at a crime scene. A simple chemical analysis concludes that the powder is a mixture of sugar and morphine (C17H19NO3), a weak base similar to ammonia. The crime lab takes 10.00 g of the mysterious white powder, dissolves it in 100.00 mL water, and titrates it to the equivalence point with 2.84 mL of a standard 0.100 M HCl solution. What is the percentage of morphine in the white powder?
-.A sample of an iron ore is dissolved in acid, and the iron is converted to Fe2+. The sample is then titrated with 57.20 mL of 0.05240 M MnO4– solution. The oxidation-reduction reaction that occurs during titration is
MnO4(aq) + Fe^2+(aq) +8H(aq) -> Mn^2+(aq) +5Fe^3+(aq) + 4H2O(l)
How many moles of MnO4– were added to the solution? (b) How many moles of Fe2+ were in the sample? (c) How many grams of iron were in the sample? (d) If the sample had a mass of 2.8890 g, what is the percentage of iron in the sample?
-A sample of 70.5 mg of potassium phosphate is added to 25.0 mL of 0.050 M silver nitrate, resulting in the formation of a precipitate. (a) Write the molecular equation for the reaction. (b) What is the limiting reactant in the reaction? (c) Calculate the theoretical yield, in grams, of the precipitate that forms.
