A boat crosses a 200m wide river at 3m/s ,north relative to water. the river flows at 1 m/s as shown . what is the velocity of the boat as observed on the river back from the boat departed

What is the fate of the electrons that interact with a specimen in an electron microscope?

Distinguish between a transverse wave and a longitudinal wave.

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. (2.15 mpa; 45.0 mw; 42.6%)
