Answer:
Explanation:
It is a circuit where there is only one path for the current, from the power supply source through all the elements of the circuit (Receiver, metallic material that allows the circulation of the electric current, Power source), so that no there is neither independence nor distinction in the different places of this.
Answer: Tenga en cuenta que sinh3 = 3 − − 32 sinh 3t = mi 3 t - mi - 3 t 2 Por eso, 2sinh3 = 4 − − 2

Power=4Kw
Explanation:
Hi!
To solve follow the steps below!
1. Find the density of the air at the entrance using the equation for ideal gases
where
P=pressure=120kPa
T=20C=293k
R= 0.287 kJ/(kg*K)=
gas constant ideal for air
2.find the mass flow by finding the product between the flow rate and the density
m=(density)(flow rate)
flow rate=10L/s=0.01m^3/s
m=(1.43kg/m^3)(0.01m^3/s)=0.0143kg/s
3. Please use the equation the first law of thermodynamics that states that the energy that enters is the same as the one that must come out, we infer the following equation, note = remember that power is the product of work and mass flow
Work
w=Cp(T1-T2)
Where
Cp= specific heat for air=1.005KJ/kgK
w=work
T1=inlet temperature=20C
T2=outlet temperature=300C
w=1.005(300-20)=281.4KJ/kg
Power
W=mw
W=(0.0143)(281.4KJ/kg)=4Kw
