Question: A three phase transmission line is 200 km long. It has a total series impedance of (25 + j110) Ω per phase & a total shunt admittance of j5 X 10-4 Ω-1. It delivers 180 MW at 275 kV & 0.8 power factors lagging to a load connected at the receiving end.Using the medium p model of the line, Find the current, voltage, reactive power, real power, & power factor at the sending end of the line.
A 180, 48.0 cm-diameter turntables rotate on frictionless bearings at 70.0. A 15.0 block sits at the center of turntable. A compressed spring shoots the block fundamentally outward along the frictionless groove in the surface of the turntable.
A cart carrying a vertical missile launcher moves horizontally at the constant velocity of 30.1 to the right. It launches a rocket vertically upward. The missile has an initial vertical velocity of 40.33 relative to the cart.
A 35.0-g bullet moving at 475 m/s strikes a 3.2-kg bag of flour that is on ice, at rest. The bullet passes through the bag, leaving at 225 m/s. How fast is the bag moving while the bullet exits.
A helicopter is ascending perpendicularly with a speed of 5.42 m/s. At a height of 146 m above the Earth, a package is dropped from a window. How much time does it take for package to reach the ground.
