I HAVE A QUESTION!
TYPE OF QUESTION: computing science
YOUR QUESTION: I have to write out 4 standard algorithms into python functions. (ie create a function that runs a standard algorithm and then just do the same for the other 3)
i have got the four functions (linear search, counting occurences, finding maximum value, finding minimum value) in python & working but as soon as i try to put it into a function (ie
def linearSearch( ):
-linear search program here- )
it doesnt work/output anything. ive tried adding variables in the brackets but it still doesnt work. ive tried googling it but it didnt help ):
this is about a week late & due in tomorrow.
thanks!!!!

You probably already found this since you googled, but maybe this will help: https://pythonschool.net/data-structure ... ar-search/
I avoided cs since it's my father's field, so I can't help anymore than that.

TYPE OF QUESTION: Government
YOUR QUESTION:
I am doing a project for my Government class, we are given an Amendment and have to give facts about it/brief explanation.
But I'm the type of person who likes to go all out on my projects, so I need your help.
I've got a lot of facts down, but I'm wondering if anyone else has anything else to give me?
I'll look over it and see what I can use and what I've already gotten.

Also I need to explain how this Amendment affects our lives today.

I'm also having a little trouble finding photos to go along with the Amendment, so any photos will help too.
My Amendment is #5.

I'm not sure if you are in AP US gov, but if you are, the course absolutely loves it when you attach amendments and policies back to court cases. Even in a lower civics class, I'm sure the teacher would be thrilled to see the connection.

Miranda v. Arizona is the biggest one for the 5th amendment I do believe. This is where we get our "Miranda warning/rights" from ("You have the right to remain silent. Anything you say can and will be used against you in a court of law....etc "). You might be able to find some good photos from the court cases you look up too.

You should talk about the legal system when doing the part about today. Talk about the Miranda rights, and talk about how people cannot be retried for a crime they were declared innocent of. Basically, focus on the rights of the accused.

I hope this gives you a couple more ideas!

YOUR QUESTION: Monica left Montreal driving at 30 km/h. Wendy left 2 h later and traveled the same road at 40 km/h. At what distance from Montreal will Wendy overtake Monica?

The answer is 240 km, but I'm not sure how to get there using 2 equations with 2 different variables. I've seen solutions for the question before but they only had 1 variable.

Thank you so much

You don't really need two variables. The idea is actually to simplify two equations with two variables into one solvable equation with one common variable. c:

Let's start with Wendy.
Wendy - y = 40x, where x=time and y=distance from Montreal.
Monica - y = 30x + 60.
Why +60? Because when Wendy starts moving, Monica has already driven 60km down the same road.
(You could also use Monica's location when Wendy starts driving as your reference point, make Wendy = 40x - 60, and Monica = 30x, but I find it more straightforward to use the original location.)

Now you have two equations, and you want to find the intersection/time of when Wendy catches up to Monica. The y coordinate is location, and they will be at the same location when Wendy catches up, so y1 and y2 are equal. Equate them to each other and you get: 40x = 30x + 60, solve.
x is still time, so that's when Wendy and Monica are in the exact same spot.
Substitute x into either of the original equations and you get the distance either has travelled from Montreal (y).

Good luck!~

I HAVE A QUESTION!

TYPE OF QUESTION:
biology

YOUR QUESTION:
I need to make a Venn diagram comparing DNA and RNA, and I got a few differences and similarities, but now I'm stuck and not sure if it's enough or not. Here's what I've got:

• includes the sugar Deoxyribose
• includes Thymine
• contains 2 base strands
• holds genetic information

• include phosphate groups and nitrogenous bases
• include Adenine, Cytosine, and Guanine

• includes the sugar Ribose
• includes Uracil
• contains 1 base strand
• transcribes and translates information found in DNA for protein synthesis

Is everything I have so far correct? Am I missing anything major? Keep in mind this is a high school course, so the lessons cover just the basics for the most part.

Thank you! ;w;

ETA: apparently I need at least 3 similarities between them but I can't think of what the last one is?

For both: Include 5 carbon sugars, have nucleotides
DNA: found in cell nuclei
RNA: functions in protein production

Hope this can help a little bit, but you covered most of it

TYPE OF QUESTION:Chemistry
YOUR QUESTION:

Ammonia can also be synthesized by the reaction:
3H2(g)+N2(g)→2NH3(g)
What is the theoretical yield of ammonia, in kilograms, that we can synthesize from 5.54 kg of H2 and 32.2 kg of N2?

I am not even sure how to tackle this question since our teacher hasn't taught us how to do these questions, yet homework is done on Sunday night.

I am not even sure how to tackle this question since our teacher hasn't taught us how to do these questions, yet homework is done on Sunday night.

This problem is called a limiting reaction where the amount of the product (NH3) is made by it's limiting reactant (which is what you have to find: is it the H2 or the N2)

Here's a link to notes that I used which does an example of that problem, (note the measurements are in grams)

Your answer would be the reactant that is the smallest number or amount

and if you need more help I'll be happy to help you further it's just that I don't know if you've done stoichiometry (ex; grams to moles)
Hope this helps! <3 (Edit I worked out the problem and it's on the page of notes if you want to see it please excuse the poor lighting >.<)

Thank you so much! I need all the help I can get since I'm struggling. We haven't really gone over stoich yet, but we are supposed to know how to do it.

So the limiting reactant would be the smallest amount of grams right? So if you know the limiting reactant how would you figure out how many grams a product would be?
