A round rotor 60 Hz synchronous generator has Eg = 2.0 per unit and Xs = 1.5 per unit. a. (5 points) In steady state the generator delivers 0.8 per unit real power (P) to an infinite bus with V = 1.0 per unit. Find the steady state value of the rotor angle, o. b. (5 points) If the answer to part (a) is 0.6 radians (it’s not), find the value of the stiffness coefficient o.

The act of moving from one place to another. a. locomotor b. aerobic c. stationary d. static

The atoms in a nickel crystal vibrate as harmonic oscillators with an angular frequency of 2.3 × 1013 rad/s. the mass of a nickel atom is 9.75 × 10-26 kg. what is the difference in energy between adjacent vibrational energy levels of nickel? (h = 6.626 × 10-34 j • s, , 1 ev = 1.60 × 10-19 j)

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
