El verso es un conjunto de palabras que están en línea, Una estrofa es un conjunto de versos que van separadas por un espacio a, ¿Cuántos versos y cuántas estrofas tiene el poema el Marinerito? POEMA EL MARINERITO Tú fuiste marinerito en la noche lunada tan alegre y bonito contento a la mar salía. Cinco delfines rameros Su barca acompañaba dos ángeles marineros invisibles lo guiaba. Tendió las redes con fuerza Por sobre la mar salada Resplandeciente la luna llena Solo en la red plateada. Rafael Alberti.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.
