1.  A rectangular loop of wire (0.2 m wide and 0.3 m tall) carrying a current of 0.6 A is in the xy plane, with its right edge along the +y axis. A magnetic field (uniform, B = 1.2 T) exists along a direction that is 74° from the +z axis in the xz plane. What magnitude of torque will act on the loop of wire at that moment ? a) 0.42 Nm b)0.15 Nm c) 0.04 Nm d) 0.09 Nm

2. If the B-field in the previous problem was oriented at 50° from +x in the xz plane determine the magnitude and direction of the torque on a 150 turn loop of the same size as the coil in question#1. a) 4.2 Nm, along +y b) 2.8 Nm, along +y c) 1.1 Nm, along +z d) 0.5 Nm, along +z

3. Will the plane of the coil of wire in question #2 initially swing toward the +z or the -z axis? a) +z b) -z c) Neither +z nor -z

4. For the torque on a current carrying loop to be maximized, the angle between the normal to the plane of the loop and the B-field must be: a) zero. b)45°. c) 90° d) 180°

In Java, write a program that solves the following problem.

An arena can seat 12,000 people for an event. If the arena was full and you were to poll everyone for which day of the year (between 1 and 365, inclusive) they were born, determine which days had the most birthdays and which days had the fewest birthdays.

Write a program that will generate 12,000 random birthdays (integer numbers) between 1 and 365 and count how many people have that same birthday. Output a listing of the days that have the most birthdays and the days that have the fewest birthdays. You do not need to convert a number like 32 to an actual date (February 1^st).

Do NOT change your class name from "Main". Your filename should be "Main.java".

Your code will have two classes:

• the Main class will hold the main() method.
  • From this class, you will create an object of the Arena class.
  • This object will call responsible methods in the Arena class to print the MAX and MIN birthday dates.
• the Arena class will have a random number generation method.
  • This class's constructor will take #of people in the area as an input.
  • With this number, you will create an array and a method will put random numbers between 1 and 365 in this array.
  • Two other methods in this class will determine the days with MAX and MIN birthdays.
  • Make sure to print ALL maximum and minimum birthdate days.

The two classes can be part of the same file. A naive example structure is shown below.

public class Main{

public static void main(String args[]){
Arena a = new Arena();
a.printArena();
}
}

class Arena{
void printArena() {
System.out.println("I am arena");
}
}

Sample Output

The following days have 75 people:

147

The following days have 35 people:

The solute HCl(A) is diffusing through a 2-mm thick film of water (B) at 283 K. The concentration of HClat point 1 at one boundary of the film is 12 wt% HCl(density r1=1060 kg/m3), and at the other boundary at point 2 it is 6 wt% HCl(r2=1030.3 kg/m3.) Take diffusion coefficient of HClin H2O as 2.5e-9 m2/s, assume steady state and one boundary impermeable to water. Calculate the flux of HCl ( in mol/m^2*s)

The production of yogurts is carried out by adding a specific strain of bacteria to pasteurised milk. The bacteria consumes lactose in the milk to produce lactic acid. Assume the fermentation reaction can be simplified by the following reaction:

Lactose (A) + bacteria cells (C) à more bacteria cells (C) + lactic acid (R)

The data below shows the concentration of lactose from a 2 L mixed flow reactor at 40 ^oC.

First, create a class object named SequenceMap that has as private data members the following two:

string recognition_sequence_ ;

vector enzyme_acronyms_;

Other than the big-five (note that you can use the defaults for all of them), you have to add the following:

a) A constructor SequenceMap(const string &a_rec_seq, const string &an_enz_acro),that constructs a SequenceMap from two strings (note that now the vector enzyme_acronyms_ will contain just one element, the an_enz_acro).

b) bool operator<(const SequenceMap &rhs) const, that operates based on the regular string comparison between the recognition_sequence_ strings (this will be a one line function).

c) Overload the operator<< for SequenceMap.

d) void Merge(const SequenceMap &other_sequence). This function assumes that the object’s recognition_sequence_ and other_sequence.recognition_sequence_ are equal to each other. The function Merge() merges the other_sequence.enzyme_acronym_ with the object’s enzyme_acronym_. The other_sequence object will not be affected.

Please test it with your own test functions to make sure that it operates correctly.

Please also show the test functions that you utilize so I can also implement it.

thank you.
