Answer:
C
Explanation:
the total resistance is equal to the total potential difference divided by the Current
Both A and B technicians are correct because both might be used to test fuses, according to technician B.
<h3>What is continuity?</h3>
The behavior of a function at a certain point or section is described by continuity. The limit can be used to determine continuity.
From the question:
We can conclude:
The technician claims that you may check for continuity using both an ohmmeter and a self-powered test light. Both might be used to test fuses, according to technician B.
Thus, both A and B technicians are correct because both might be used to test fuses, according to technician B.
Technician A says both an ohmmeter and a self-powered test light may be used to test for continuity. Technician B says both may be used to test fuses. Who is correct?

Answer:
16.2 cents
Explanation:
Given that a homeowner consumes 260 kWh of energy in July when the family is on vacation most of the time.
Where Base monthly charge of $10.00. First 100 kWh per month at 16 cents/kWh. Next 200 kWh per month at 10 cents/kWh. Over 300 kWh per month at 6 cents/kWh.
For the first 100 kWh:
16 cent × 100 = 1600 cents = 16 dollars
Since 1 dollar = 100 cents
For the remaining energy:
260 - 100 = 160 kwh
10 cents × 160 = 1600 cents = 16 dollars
The total cost = 10 + 16 + 16 = 42 dollars
Note that the base monthly of 10 dollars is added.
The cost of 260 kWh of energy consumption in July is 42 dollars
To determine the average cost per kWh for the month of July, divide the total cost by the total energy consumed.
That is, 42 / 260 = 0.1615 dollars
Convert it to cents by multiplying the result by 100.
0.1615 × 100 = 16.15 cents
Approximately 16.2 cents
Answer:
19063.6051 g
Explanation:
Pressure = Atmospheric pressure + Gauge Pressure
Atmospheric pressure = 97 kPa
Gauge pressure = 500 kPa
Total pressure = 500 + 97 kPa = 597 kPa
Also, P (kPa) = 1/101.325 P(atm)
Pressure = 5.89193 atm
Volume = 2.5 m³ = 2500 L ( As m³ = 1000 L)
Temperature = 28 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (28.2 + 273.15) K = 301.15 K
Using ideal gas equation as:
PV=nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
5.89193 atm × 2500 L = n × 0.0821 L.atm/K.mol × 301.15 K
⇒n = 595.76 moles
Molar mass of oxygen gas = 31.9988 g/mol
Mass = Moles * Molar mass = 595.76 * 31.9988 g = 19063.6051 g
Answer:
(e) 1.64 kW
Explanation:
The Coefficient of Performance of the Reverse Carnot's Cycle is:
![COP = \frac{T_{L}}{T_{H}-T_{L}}](https://tex.z-dn.net/?f=COP%20%3D%20%5Cfrac%7BT_%7BL%7D%7D%7BT_%7BH%7D-T_%7BL%7D%7D)
![COP = \frac{293.15\,K}{308.15\,K-293.15\,K}](https://tex.z-dn.net/?f=COP%20%3D%20%5Cfrac%7B293.15%5C%2CK%7D%7B308.15%5C%2CK-293.15%5C%2CK%7D)
![COP = 19.543](https://tex.z-dn.net/?f=COP%20%3D%2019.543)
Lastly, the power required to operate the air conditioning system is:
![\dot W = \frac{\dot Q_{L}}{COP}](https://tex.z-dn.net/?f=%5Cdot%20W%20%3D%20%5Cfrac%7B%5Cdot%20Q_%7BL%7D%7D%7BCOP%7D)
![\dot W = \frac{32\,kW}{19.543}](https://tex.z-dn.net/?f=%5Cdot%20W%20%3D%20%5Cfrac%7B32%5C%2CkW%7D%7B19.543%7D)
![\dot W = 1.637\,kW](https://tex.z-dn.net/?f=%5Cdot%20W%20%3D%201.637%5C%2CkW)
Hence, the answer is E.
