For any string w = w1w2 · · · wn, the reverse of w, written w R, is the string w in reverse order, wn · · · w2w1. For any language A, let A R = {w R| w ∈ A}. Show that if A is regular, so is A R.

gas and liquid

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation

it is b. absorbs thermal energy
