. At typical nuclear power plants, refueling occurs every 19 months. Assuming that a plant has operated continuously since the last refueling and produces 1.2 GW of electrical power at an efficiency of 35%, how much less massive are the fuel rods at the end of the 19 months than at the start? (Assume 30-day months.)

The two required components for a generator

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
