Homework help : What object rotates at 90 RPM?

AI Thread Summary
An object with an angular velocity of 3π radians per second translates to approximately 90 RPM. To identify such an object, it's suggested to convert the angular velocity into more common units and conduct a Google search for "90 RPM." Participants are encouraged to demonstrate their effort in solving the problem before seeking assistance. The discussion emphasizes the importance of research and conversion in understanding angular velocity. Engaging with the problem through these methods can lead to identifying suitable objects that rotate at this speed.

What do you think? Per the forum rules, you must show that you've put some effort into the problem before getting help.

As per the instructions, try converting the 3 \pi \ \mathrm{\frac{rad}{sec}} to more common, everyday units. Then do a google search. See what you come up with.
 
I apologize, I’m new to the forum but this is what I’ve gotten so far, I am not able to identify an object that has an RPMof 90.

Okay, good so far.

Type in "90 rpm" into google search, and see what hits you get.

Thread 'Minimum mass of a block'
Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...
TL;DR Summary: Find Electric field due to charges between 2 parallel infinite planes using Gauss law at any point Here's the diagram. We have a uniform p (rho) density of charges between 2 infinite planes in the cartesian coordinates system. I used a cube of thickness a that spans from z=-a/2 to z=a/2 as a Gaussian surface, each side of the cube has area A. I know that the field depends only on z since there is translational invariance in x and y directions because the planes are...
