A three-phase Y-connected source is energizing a Δ-connected load. The phase voltage of the transmission line is = 120∠0 ∘, and the load impedance is ∆ = 9∠30∘Ω. Compute and the power consumed by the load.

Calculate the kinetic energy of earth due to its spinning about its axis. krot = j compare your answer with the kinetic energy of the orbital motion of earth's center of mass about the sun. assume earth to be a homogeneous sphere of mass 6.00 1024 kg and radius 6.40 106 m. the radius of earth's orbit is 1.50 1011 m.

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.
