-- First, we have to decide how to handle the two resistors.
The effective resistance of resistors in series is the sum
of their individual resistances. That is, they act like a single
resistor, whose resistance is the sum of all of them.
So in this question, the 4.0 ohms and the 7.5 ohms act like a
single resistor of 11.5 ohms.
-- The current in the circuit is
(the supply voltage) / (the total resistance)
= (9.0 volts) / (11.5 ohms)
= 0.783... Ampere (rounded)
Answer:
2.61 atm
Ley de Boyle
Explanation:
= Presión inicial = 0.96 atm
= Presión final
= Volumen inicial = 95 mL
= Volumen final = 35 mL
En este problema usaremos la ley de Boyle.
La presión ejercida sobre el émbolo para reducir su volumen es de 2.61 atm.
Answer:
Carbon dioxide and water
Explanation:
The products of complete combustion are always carbon dioxide and water.
The balanced reaction is:
4 CH₃OH + 3 O₂ → 4 CO₂ + 2 H₂O
