Steam at 4 MPa and 4008C enters a nozzle steadilywith a velocity of 60 m/s, and it leaves at 2 MPa and 3008C. The inlet area of the nozzle is 50 cm2, and heat is being lost at a rate of 75 kJ/s. Determine (a) the mass flow rate of thesteam, (b) the exit velocity of the steam, and(c) the exit area of the nozzle

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
