Answer:
The answer is 100% A THE ANSWER IS A!!!!
Explanation:
i have a 100 in all of my classes including science
The voltage as a function of time for the power source oscillating at the given frequency is determined as V = 169.7sin(120πt).
<h3>
Peak voltage</h3>
The peak voltage of the source is calculated as follows;
Vrms = 0.7071V₀
120 = 0.7071V₀
V₀ = 120/0.7071
V₀ = 169.7 V
<h3>Angular frequency of the wave</h3>
ω = 2πf
where;
f is frequency = 60 Hz
ω = 2π x 60
ω = 120π rad/s
<h3>Voltage equation as function of time</h3>
V = V₀sin(ωt)
V = 169.7sin(120πt)

Answer: The final answer is 1,700 J
Explanation: According to first law of thermodynamics:
=Final energy-initial energy=Change in internal energy
q = heat absorbed or released
w = work done by or on the system
w = work done by the system= {Work done by the system is negative as the final volume is greater than initial volume}
q = +500J {Heat absorbed by the system is positive}
w = work done by the system = -300J
U2- 1500J= + 500J --300J
U2= 1700J
C
