Signals from radio sources statistically look like noise". this is because we receive the signals from many, many electrons that are emitting sine waves of arbitrary amplitudes, frequencies, and phases. 1. explain in your own words why we receive the signal from many electrons (rather than just a single electron, or a few electrons) and why they all emit signals of different amplitudes, phases and frequencies. 2. what does "statistically looks like noise" mean? what properties of noise does this signal have? 3. demonstrate (in python) that such a signal will have noise-like properties

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
