A frictionless, horizontal, simple harmonic oscillator has a mass of 0.15 kg and 0.030 J of mechanical energy. What are the oscillator's frequency and the stiffness of the spring if the amplitude of its oscillation is 2.5 cm?
An "astronomical unit" (AU) is equal to the Earth's semimajor axis in its orbit around the Sun, or 1.50 x 10 11 m. An asteroid is discovered which has a semimajor axis of 5.6 AU. What is the period of the asteroid's orbit about the Sun?
Explain how the process of "doping" a semi conductor can improve its overall efficiency. Why does "doping" require a clean room infrastructure
