Click For Summary
The discussion centers on the factor label method, which is a technique used for unit conversion in calculations. Participants emphasize the importance of demonstrating understanding by explaining the method in one's own words before seeking help. A specific example involves calculating charges between companies while considering units. Additionally, there is a cautionary note about consulting experts for real-life applications, particularly regarding medication dosages, as mathematics alone may not suffice. The conversation highlights that the query is related to a homework problem rather than a practical scenario.

Homework Statement
1 .You want to have a 30 m2 room in your house retiled. A company called Wasta Tiles will do it for $50
per m2
. Another company, Zaki Floors, will do it for $4 per ft2
. Which company has the lower price?
Justify your answer using the factor label method. 1 m2 = 10.8 ft2



2. A patient needs 0.50 mg of a certain drug per 10.0 pounds of body weight. Each pill contains 4.00 mg of
the drug. If the patient weighs 73.0 kg, how many pills should the patient be given? (1 kg weighs 2.2
pounds). Use the factor label method
Relevant Equations
1 kg weighs 2.2 pounds

You need to show some work first. For instance, please tell us in your own words, what is the "factor label method".
 
For 1: Money charged by one company is already given. Calculating the charges by the other company (while keeping the unit in mind) will solve the problem.

For 2: Consult an expert! Only Mathematics is not sufficient to know the correct dosage of a medicine!

This is a homework problem, not a real-life case.

Thread 'Coulomb's force vs the Lorentz force'

Beams of electrons and protons move parallel to each other in the same direction. They ______. a. attract each other. b. repel each other. c. neither attract nor repel. d. the force of attraction or repulsion depends upon the speed of the beams. This is a previous-year-question of CBSE Board 2023. The answer key marks (b) as the right option. I want to know why we are ignoring Coulomb's force?

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...

Thread 'Speed of moth related to Doppler Effect'

I treat this question as two cases of Doppler effect. (1) When the sound wave travels from bat to moth Speed of sound = 222 x 1.5 = 333 m/s Frequency received by moth: $$f_1=\frac{333+v}{333}\times 222$$ (2) When the sound wave is reflected from moth back to bat Frequency received by bat (moth as source and bat as observer): $$f_2=\frac{333}{333-v}\times f_1$$ $$230.3=\frac{333}{333-v}\times \frac{333+v}{333}\times 222$$ Solving this equation, I get ##v=6.1## m/s but the answer key is...
