In a metabolic experiment a 229 gm rat consumed 30 ml of oxygen in 7 min. Calculate the oxygen consumption per hour. Calculate the metabolic rate in ml O2/Kg/hr.

A motivational speaker claims that wearing red on the day of an exam “energizes” the brain and improves performance. Your psychology professor doubts that this is true. Design an experiment that would test whether the speaker is correct.

Is there any general relation between the amount of charge possesses and its range in air? Were any bremsstrahlung produced in an experiment of absorption of beta particles ? How may bremsstrahlung production be minimized?

Intro to Python

I'm getting trouble obtaining the solution for the following questions:

"How many babies were born with names starting with that least-common letter?" For the file used it is "U"

"How many babies were born with names starting with that-common letter"? For the file used it is "A"

"How many people have that name?" (This follows the question "By default, the Social Security Administration's data separates out names by gender. For example, Jamie is listed separately for girls and for boys. If you were to remove this separation, what would be the most common name in the 2010s regardless of gender?" And the file I used it is "Isabella")

"What name that is used for both genders has the smallest difference in which gender holds the name most frequently? In case of a tie, enter any one of the correct answers."

This is the problem:

#-----------------------------------------------------------
#The United States Social Security Administration publishes
#a list of all documented baby names each year, along with
#how often each name was used for boys and for girls. The
#list is used to see what names are most common in a given
#year.
#
#We've grabbed that data for any name used more than 25
#times, and provided it to you in a file called
#babynames.csv. The line below will open the file:

names_file = open('../resource/lib/public/babynames.csv', 'r')

#We've also provided a sample subset of the data in
#sample.csv.
#
#Each line of the file has three values, separated by
#commas. The first value is the name; the second value is
#the number of times the name was given in the 2010s (so
#far); and the third value is whether that count
#corresponds to girls or boys. Note that if a name is
#given to both girls and boys, it is listed twice: for
#example, so far in the 2010s, the name Jamie has been
#given to 611 boys and 1545 girls.
#
#Use this dataset to answer the questions below.

#Here, add any code you want to allow you to answer the
#questions asked below over on edX. This is just a sandbox
#for you to explore the dataset: nothing is required for
#submission here.

//

This is the format of the file but this is not file the problem is based on:

Isabella,42567,Girl
Sophia,42261,Girl
Jacob,42164,Boy
Emma,35951,Girl
Ethan,34523,Boy
Mason,34195,Boy
William,34130,Boy
Olivia,34128,Girl
Jayden,33962,Boy
Ava,30765,Girl

I found the solution and it's this:

baby_list.append([name,count,gender])

Summary

Figure 3–79 shows an example page containing two applications of floating objects. In the first line of Lincoln’s second inaugural speech a drop capital is created by floating the first letter of the first paragraph next to the surrounding text. The text of the speech is wrapped around the image of Lincoln using an irregular line wrap. This effect is created by cutting the Lincoln image into separate strips which are floated and stacked on top of each other. In this Coding Challenge you will explore how to create both effects.

^{Figure 3-79}

Do the following:

1. Open the files code3-1.html and code3-1_float.css and in the comment section enter your name (First + Last) and the date (MM/DD/YYYY) into the Author: and Date: fields of the file.

2. Go to the code3-1.html file in your editor. Within the head section insert a link element linking the page to the code3-1_float.css style sheet file. Take some time to study the content of the page.

3.lOpen the file code3-1_float.css, and for all img elements create a style rule to set the height of the image to 3.3em. Float all img elements on the right margin, but only when the right margin is first cleared of any floats. (Hint: clear: right).

4. To create a drop cap insert a style rule for the selector p:first-of-type::first-letter and add the following styles:

1. Float the element on the left margin.
2. Set the font size to 4em and the line height to 0.8em.
3. Set the size of the right margin and padding space to 0.1em. Set the bottom padding to 0.2em.

5. Display the first line of the speech in small caps by adding a style rule for the selector p:first-of-type::first-line that changes the font variant to small-caps and the font size to 1.4em.

6. Open the page in the browser preview and verify the layout of the page resembles that shown in Figure 3-79.

      it must needs be that offenses come; but woe to that man by whom the offense

      in the providence of God, must needs come, but which, having continued through his

      appointed time, he now wills to remove, and that he gives to both North and South

      this terrible war, as the woe due to those by whom the offense came, shall we discern

      therein any departure from those divine attributes which the believers in a living

      God always ascribe to him?

   <p>Fondly do we hope &mdash; fervently do we pray &mdash; that this

      mighty scourge of war may speedily pass away. Yet, if God wills that it continue

      until all the wealth piled by the bondsman's two hundred and fifty years of unrequited

      toil shall be sunk, and until every drop of blood drawn by the lash shall be paid by

      another drawn with the sword, as was said three thousand years ago, so still it must

      be said, "The judgments of the Lord are true and righteous altogether."

   <p>With malice toward none; with charity for all; with firmness in the right, as God

      gives us to see the right, let us strive on to finish the work we are in; to bind up

      the nation's wounds; to care for him who shall have borne the battle, and for his

      widow, and his orphan &mdash; to do all which may achieve and cherish a just and lasting peace

      among ourselves, and with all nations.
