En un experimento de laboratorio, se utiliza un calorĂmetro para determinar el calor especifico del hierro. Se colocan 80 g de balines de hierro seco en la taza y se calienta a 95°C. La masa de la taza interior de aluminio con un agitador del mismo material es de 60 g. El calorĂmetro se llena parcialmente con 150 g de agua a 18°C. Los balines calientes se vacĂan rápidamente en la taza y se sella el calorĂmetro, como muestra la figura 17.5. DespuĂ©s que el sistema ha alcanzado el equilibrio tĂ©rmico, la temperatura final es 22°C. Calcule el calor especifico del hierro.

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 Ëšf and standard atmospheric pressure, what is the value of the mach number?
