the adiabatic compressor of a refrigeration system compresses saturated r-134a vapor at 0°c to 600 kpa and 50°c. what is the isentropic efficiency of this compressor? use the tables for r-134a.

What is the frequency of a light wave with a wavelength of 620nm

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.

An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 26 mm and 103 mm. the electric potential of the inner conductor with respect to the outer conductor is - 700 v (k = 1/4πε 0 = 8.99 × 109 n · m2/c2) the energy stored in a 1.0-m length of this capacitor is closest to
