una cinta transportadora a debe girar a 5 rpm. El eje del motor, que gira a una velocidad de 3000 rpm y cuyo diámetro mide 2 mm, está conectado a una polea de 100 mm de diámetro. Sobre el eje de ésta se monta una nueva polea de 8 mm de diámetro que se une, mediante una correa, a la polea que arrastra a la cinta.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

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

= final temperature = ?

using the equation
