Answer:
Explanation:
Our values are,
State 1
We know moreover for the tables A-15 that
State 2
For tables we know at T=320K
We need to use the ideal gas equation to estimate the mass, so
Using now for the final mass:
We only need to apply a energy balance equation:
The negative value indidicates heat ransfer from the system
The precautions that should be taken to avoid the overloading of domestic electric circuits are:
- Do not put high voltage wires in one socket.
- Do not use many electric appliances of high power at the same time.
<h3>What are electric circuits?</h3>
Electric circuits are wires or devices that give electricity to devices that run on electricity. Running of electric devices should be done carefully because our body can come in contact with the current.
Thus, the precautions are to keep high voltage lines away from one socket. Use only a few high-power electric appliances at once.

The answer is deindividuation - a psychological state in which a person does not feel individual responsibility.
Answer:
Z = 29.938Ω ∠22.04°
I = 2.494A
Explanation:
Impedance Z is defined as the total opposition to the flow of current in an AC circuit. In an R-L-C AC circuit, Impedance is expressed as shown:
Z² = R²+(Xl-Xc)²
Z = √R²+(Xl-Xc)²
R is the resistance = 4Ω
Xl is the inductive reactance = ωL
Xc is the capacitive reactance =
1/ωc
Given C = 12 μF, L = 6 mH and ω = 2000 rad/sec
Xl = 2000×6×10^-3
Xl = 12Ω
Xc = 1/2000×12×10^-6
Xc = 1/24000×10^-6
Xc = 1/0.024
Xc = 41.67Ω
Z = √4²+(12-41.67)²
Z = √16+880.31
Z = √896.31
Z = 29.938Ω (to 3dp)
θ = tan^-1(Xl-Xc)/R
θ = tan^-1(12-41.67)/12
θ = tan^-1(-29.67)/12
θ = tan^-1 -2.47
θ = -67.96°
θ = 90-67.96
θ = 22.04° (to 2dp)
To determine the current, we will use the relationship
V = IZ
I =V/Z
Given V = 12V
I = 29.93/12
I = 2.494A (3dp)
