El calor especifico del agua es de 4184 J/kg ·K ¿en cuantos joules cambia la energia interna de 50 g de agua cuando se calienta desde 21ºC hasta 37ºC? Suponga que la dilatacion del agua es despreciable el calor añadido para aumentar la temperatura del agua es AQ= cm Ar = (4184J/kg·K) (0.050 kg)(16ºC)=3.4x10´3J

What is the missing step in this proof ?

You paid 28.00 for 8 gallons of gasoline. how much would you pay for 15 gallons of gasoline?

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
