Astudent measures the speed of yellow light in water to be 2.00 x 10(to the 8th power) meters per second, 1.87 x 10(to the 8th power) meters per second, and 2.39 x 10(to the 8th power) meters per second. if the accepted value for the speed is 2.25 x 10(to the 8th power) meters per second, the students measurements are 1) precise, only 2) accurate, only 3)both precise and accurate 4)neither precise nor accurate

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

Why is metal often used for cooking pan?

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines.
