Consider a cylindrical specimen of some hypothetical metal alloy that has a diameter of 8.0 mm (0.31 a tensile force of 1000 n (225 lbf) produces an elastic reduction in diameter of 2.8 × 10−4 mm (1.10 × 10−5 compute the elastic modulus for this alloy, given that poisson's ratio is 0.30.

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.

What sort of waves exhibit the doppler effect?

In a hydrogen molecule there are a total of four charges, 2 protons in the two nuclei, and 2 electrons. how many unique charge-pairs are there (without double counting)?
