Applying Dalton's Law: From Popcorn Launchers to Innovative Products

Click For Summary
The discussion revolves around a student's assignment to apply Dalton's Law to improve an existing product or create a new one. An example provided is a popcorn launcher, illustrating the challenge of finding practical applications for the law. The student expresses frustration at the perceived limitations of Dalton's Law in fostering innovative ideas. Responses emphasize academic integrity, discouraging attempts to use the forum for homework help without personal input. The thread ultimately highlights the importance of creativity and original thought in applying scientific principles.

Summary: TL;DR: Doing an assignment in which we are to apply Dalton's Law to a product to improve/ better it OR create a completely new product using the law. Let your creativity run wild!

Hi there! I am doing an assignment in which we are to apply Dalton's Law to a product to improve/ better it OR create a completely new product using the law.

An example of a new product could be a popcorn launcher (a "gun" that shoots kernels out of it). The group that is doing this is doing the Ideal Gas Law. In my case, I am doing "Dalton's Law," which seems to be a pretty intuitive, somewhat useless law to apply to an innovative product.

Desperate for ideas! Let your creativity run wild!

Ah, the plot thickens. The OP apparently tried to delete his first post, perhaps because he didn't like that his attempt at cheating on his schoolwork exposed. Little does he know that Mentors have superpowers. Wait one...

Thread 'Chain falling out of a horizontal tube onto a table'
My attempt: Initial total M.E = PE of hanging part + PE of part of chain in the tube. I've considered the table as to be at zero of PE. PE of hanging part = ##\frac{1}{2} \frac{m}{l}gh^{2}##. PE of part in the tube = ##\frac{m}{l}(l - h)gh##. Final ME = ##\frac{1}{2}\frac{m}{l}gh^{2}## + ##\frac{1}{2}\frac{m}{l}hv^{2}##. Since Initial ME = Final ME. Therefore, ##\frac{1}{2}\frac{m}{l}hv^{2}## = ##\frac{m}{l}(l-h)gh##. Solving this gives: ## v = \sqrt{2g(l-h)}##. But the answer in the book...
