An ideal Stirling cycle uses 0.12 kg of air as the working fluid. The lower temperature at which energy is exchanged is 300 K while the upper temperature is 2000 K. Air is at 150 kPa at the beginning of compression and the peak pressure is 3 MPa. Assume that an ideal regenerator is used. Determine a) the energy captured and supplied by the regenerator, b) the net work from the cycle, c) the thermal efficiency of the cycle. Assume constant specific heats.

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
