Vinyl Record Rpm

help please physics question?

An old-fashioned single-play vinyl record rotates on a turntable at 54.0 rpm. What are (a) the angular velocity in rad/s and (b) the period of the motion?

i really need to find out how to find serious collectors of vinyl 45rpm and 33 1/3 rpm records –?

physics question, help?

An old vinyl record rotates at 45 rpm. What is the time period (T) of this motion? Give your answer in seconds, and do not enter units.

Vintage vinyl…..45′s and 33′s……?

I have recently been purchasing old 45 RPM records for a decorating project. I have noticed that many of the 45′s I see for sale have had a small hole drilled through the paper label covered part–right beside the hole used for stacking the record on the turntable. Anybody have any idea why that would have been done? Could it be the equivalent of paperbacks with the front cover torn off? (when they were donated, etc instead of sold)
Rollover Mikey….Ah. I thought as much. Thanks for the info!

Physics question regarding angular speed and time period?

An old vinyl record rotates at 45 rpm. What is it’s angular speed in radians per second?

With reference to questions 1, what is the time period of the 45 rpm record? Please give answer in seconds?

Any help with this question is appreciated.

What are (a) the angular velocity in rad/s and (b) the period of the motion?

An old-fashioned single-play vinyl record rotates on a turntable at 34.0 rpm.

How To Clean Old Vinyls?

I have a bunch of old vinyl 33 rpm records that are old and dusty, what can I use to clean them?

RPM question.?

An old-fashioned vinyl record rotates on a turntable at 18 rpm.

Find the angular velocity of the motion in rad/s. And find the period of the motion. I have no idea how to do this problem.

Thank you!!
i think an RPM is 2pi

I had my little brother help, when we tried, we got

0.4719751 for the 1st question

and

300 or the period of motion, but these are wrong. :/

help with rpm and centripetal force question?

we havent done rpm so im confused with this question…grade 12 physics class.2 questions i need help with.

1. a coin is placed flat on a vinyl record, turning at 33 1/3 rpm. the coin is 13 cm from the centre of the record. What is the centripetal acceleration?

2. at distance of 25 km from the eye of a hurricane, the wind is moving at 180km/h in a circle. what is the magnitude of acceleration in meters per second squared, of the particles that make up the wind?

books answer is

1. 1.6m/s^2
2. 0.10m/s^2

i hope someone helps..

So I bought this 45 rpm record of Grateful Dead’s ‘Touch of Grey’…?

It’s awesome, it’s pressed in light gray vinyl and comes with a poster with a scene from the ‘Touch of Grey’ music video on one side and random stuff like tour dates on the other. My problem is that it has ‘Touch of Grey’ on the A AND B sides. Both sides are 4:14 long so it’s not even like it’s a shorter and longer version. The poster says it should have ‘Touch of Grey’ on the A side and ‘My Brother Esau’ of the B side. I tried to look it up online and found this website [ http://www.lonestardeadradio.com/vinyl.htm ] and towards the bottom talks about a bunch of presses of the ‘Touch of Grey’ single, but none seem to match my copy. Is this a fake repress? Or do I possibly have something cool here? I bought it for a friend of mine who is a DeadHead and I just want to try to figure it out before I give it to him and he laughs in my face or something. Any help or additional information would be great!
