Un bloque de hierro de 500g a 100C° se coloca en 500g de agua a 20C° ¿cual es la temperatura final de la mezcla de hierro y agua? ( el calor específico del hierro es aproximadamente 0.11 cal/ gC°)

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as

Achlorine atom has 17 protons and 18 neutrons. what is its mass number? what is its atomic number?

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.
