If the radius of the CD below is 6.0 cm and the angular velocity is 5.0 rad/s, what is its angular displacement in 2.0 s?

The answer would be true, hope this ! : )

Ihonestly think its because of how much water we contain lol

Iam sorry but unless you are in connections academy i can not

Question is unclear.found on internet original question: "what should isla write in the areas marked a, b, and c? x-rays, both, radio waves)a: has a longer wavelengthb: travels at the same speedc: has a higher frequencyanswers: a) has a longer wavelength  --> radio waves. in fact, radio waves have wavelength in the range of the meters, while x-rays have wavelengths of a few nanometers.b) travel at the same speed --> both. both radio waves and x-rays are electromagnetic waves, which travel (in vacuum) at the speed of light, c.c) has a higher frequency --> x-rays. in fact, the shorter the wavelength, the higher the frequency. since radio waves have longer wavelength, they have lower frequency, while x-rays frequencies are higher.
