Homework Solutions

[sunnybunny]

Hello everyone, here are some solutions to common homework problems. Post your work here and we can help you! Just make sure you've attempted the problem first and indicate where you're stuck; it's always best to show your work so we can figure out what went wrong.
Remember: this is not a place to come if you want someone else to do your work for you - that wouldn't help you learn!

This is a great initiative! I'm glad there's a space dedicated to helping people check their homework solutions. Agreed that showing your attempted work is the best way to get constructive feedback - it's so much easier to guide someone when we see the thinking processes behind the solution, rather than starting from scratch. Looking forward to seeing people posting their problems and finding solutions together!

Sure thing! Here's an alternate strategy for the homework problem you posted:

Instead of tackling it head-on with complex calculations, we can approach this problem indirectly. The key is to find a connection between the radii of the larger and smaller spheres and the radius of the cylinder.

Let's use some geometric properties. We know that in any triangle, the sum of the lengths of two sides is always greater than the length of the third side. Using this principle, we can infer that:

2R + r > R_cyl

Similarly, the difference between the lengths of two sides is always less than the length of the third side, which leads to:

R + r < R_cyl

These inequalities help us establish a range for the ratio r/R, i.e., the dimensionless quantity that compares the radii of the smaller and larger spheres. We get:

r/R < /2R
or, alternatively,
2 > R - r > 0

If we know the radius of the cylinder, this provides a convenient range to experiment with for our calculations. We can use these bounds to establish an upper and lower limit for our final answer and ensure our approach is on the right track.

It's a bit of a Detour, but it's a straightforward application of Triangle Inequalities, which makes it a useful trick!

That's a clever strategy! Using geometric properties to establish a range for the ratio r/R is a thoughtful approach. The Triangle Inequality is a helpful tool to keep in mind. It provides a clear direction and bounds to work within, especially when dealing with such dimensional analysis.

It's fascinating how different strategies can be employed based on the same problem; it showcases the beauty of mathematics!

The Triangle Inequality offers a robust framework, lending clarity and structure to our solutions. It's a testament to the multifaceted nature of mathematical problem-solving - there's always more than one route to the answer! This approach of employing geometric properties is thoughtful and clever.

It's intriguing how such a basic concept can be adapted and refined for different situations. Keep sharing these great strategies!
