# What is masses: Definition and 4 Discussions

Music for the Masses is the sixth studio album by English electronic music band Depeche Mode, released on 28 September 1987 by Mute Records. The album was supported by the Music for the Masses Tour, which launched their fame in the US when they performed at the Rose Bowl in Pasadena. The tour led to the creation and filming of the documentary/live album titled 101. This saw the band using heavy amounts of sampling, much like they did in their previous album Black Celebration.
Considered one of the band's best albums, Music for the Masses was included in the book 1001 Albums You Must Hear Before You Die.

1. ### Angular frequency of two hanging bobs of different masses

This is a the representation of the two masses. . Using Newton's second law I got the following equations assuming x1>>x2: m*x1''(t) = -k(x1-x2) m*x2''(t) = 0.5kx1-kx2 I put it in matrix form m| x1''| = | -k k| *|x1| |x2''| =| 0.5k -k| |x2| After some simplification assuming...
2. ### 2 pullies and 3 masses -Tension

Hi, If i have a system that consists of 2 pullies and 3 masses, what is the tension on each part of the string? I know that for 2 masses hanging on either side of a pulley, the tension is the same. But for 3 masses, and 2 ideal pullies(no friction) and inextensible string, is tension the same...
3. ### Newton's Second Law (Pulley Sustem)

Two masses, M1=4.0 Kg, and M2=20 Kg, are attached by a rope that crosses over a massless, frictionless pulley. M1 slides horizontally and experiences a kinetic frictional force due to its motion across the surface. The coefficient of kinetic friction is uk = 0.638. When solving the problem...
4. ### I Why is the speed of light the same everywhere in the Universe?

I have always wanted to ask this question, because there is something that I am missing. I think it should be conceivable that the speed of light is affected by masses, so that its value within the solar system would be different from its value in interstellar space and even more so in...
