PHYSICS HELP (a) A typical steam jet shoots 3.62 kg of 157°C water vapor onto an intruder. How much energy is released by the cooling of the water vapor from 157°C down to the point where it can condense, 100°C? Specific heat of water vapor is 2020J/kg°C

(b) Once cooled how much heat is released by the condensation of the water vapor? The Latent Heat of Vaporization is 2,260,000 J/kg

(c) Now that the water is in liquid form, find how much more heat is released by the water as it cool to skin temperature of 26°C, then add the other energy to find the total heat released during the entire ordeal.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Which is special about a dc circuit ? a. it has both series and parallel components b. it has only series or only parallel components c. charge moves in a single direction d. charge moves back and forth quickly

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
