A series RLC circuit consists of a 100 W resistor, a 0.15 H inductor, and a 30 µF capacitor. It is attached to a 120 V/60 Hz power line (the voltage 120V is the root mean square value). What are
a. The emf εrms
b. The phase angle ϕ
c. The average power loss
(a) The root mean square value of current in the circuit is 1.14 A.
(b) The phase angle ϕ of the circuit is 17.7⁰.
(c) The average power loss in the circuit is 136.4 W.
Capacitive and inductive reactance of the RLC circuitThe capacitive and inductive reactance of the series RLC circuit is calculated as follows;
Xc = 1/ωC
[tex]X_c = \frac{1}{2\pi f C} = \frac{1}{2\pi (60)(30 \times 10^{-6})} = 88.42 \ ohms[/tex]
Xl = ωL
Xl = 2πfL
Xl = 2π(60)(0.15)
Xl = 56.55 ohms
Impedance of the circuitThe impedance of the circuit is calculated as follows;
[tex]Z = \sqrt{R^2 + (X_c - X_l)^2} \\\\Z = \sqrt{100^2 + (88.42 -56.55)^2} \\\\Z = 104.96 \ ohms[/tex]
Rms current of the circuit[tex]I_{rms} Z = V_{rms}\\\\I_{rms} = \frac{V_{rms}}{Z} \\\\I_{rms}= \frac{120}{104.96} \\\\I_{rms}= 1.14 \ A[/tex]
Phase angleThe phase angle of the circuit is calcuated as follows;
[tex]tan \phi = \frac{X_c - X_l}{R} \\\\tan\phi = \frac{88.42 - 56.55}{100} \\\\tan\phi = 0.3187\\\\\phi = tan^{-1}(0.3187) \\\\\phi = 17.7 \ ^0[/tex]
Average power loss in the circuitThe average power loss in the circuit is calculated as follows;
[tex]P = I_{rms}^2 Z\\\\P = (1.14)^2 (104.96)\\\\P = 136.4 \ W[/tex]

Employees are working within an excavation that is more than 4 foot deep and cannot safely exit the site. What is a hazard that needs to be addressed in this situation?
Select the best option.
Access/Egress
Oxygen Deficiency and Toxic Fumes
Water Accumulation
A hazard that needs to be addressed in the given situation is Access/Egress. Option A is correct.
What is the significance of Access and Egress?When handling a security or emergency scenario, access and egress points are crucial. It is crucial to have rapid access to and exit from the building in case of an emergency.
Planning entrance and egress locations should be done while creating evacuation routes. A safe escape that people can use in an emergency is called emergency egress. In an emergency circumstance like a fire, emergency access and escape are crucial.
In the given case, Employees are working within an excavation that is more than 4 foot deep and cannot safely exit the site, this is clearly deined that the Access/Egress is a hazard that must be dealt.
Therefore, option A is correct.

during a load test, a battery's voltage drops below a specific value. what action should the technician take?
A. Recharge and retest.
B. Allow battery to become fully discharged and retest.
C. immediately replace
D. None if above
Answer:
B
Explanation:
allow battery to become fully discharged and retest
When fully charged, a normal 12-volt automotive battery will have about 12.6 volts. The voltage just needs to fall to about 10.5 volts to be deemed fully discharged. The battery will suffer harm owing to severe sulfation if it falls below that level. Thus, option B is correct.
What battery's voltage drops below a specific value?Changes in Voltage Occur During Discharge, The voltage of each cell is approximately 2.5 to 2.7 volts before the charging circuit is opened at the conclusion of a charge. The voltage of the cell rapidly reduces to roughly 2.1 volts within three or four minutes of the charging circuit being opened.
The voltage across the battery terminals decreases if a load is connected across the battery. The battery's internal resistance is to blame for this voltage drop. By measuring the open-circuit voltage and the voltage across the battery's terminals when a load is connected, we can determine the internal resistance.
Therefore, allow battery to become fully discharged and retest should the technician take.

Personal water filters solve the problem of having access to safe drinking water anywhere. They are available and affordable. The materials used to make them are durable. They protect, rather than harm, users. Overall, the benefits outweigh the risks.
Explanation:
i just know its right because its the sample response :D
The personal water filter meets the following requirements: It cleans tap water for domestic use, is reasonably priced, and is easy to transport.
What is water filter?A water filter reduces water contamination through the use of a thin physical barrier, a chemical reaction, or a biological reaction to remove contaminants.
Conditions were satisfied in the example scenario:
Functionality: The personal water filter is capable of effectively removing germs and other pollutants from water.The filter is portable and convenient to use while traveling or camping because it is small and light.Affordability: The filter is a reasonable solution for those on a tight budget, costing around $20 or so.Durability: The filter can resist the wear and tear of continuous use thanks to its durable plastic design.Unmet requirements:
Heavy Metal Removal: In locations where water sources are tainted with such substances, the filter's inability to remove heavy metals from water raises some questions.In locations where water supplies are contaminated with these bacteria, the filter's ineffectiveness at removing viruses may be a problem.In regions where only saltwater is accessible, the filter's inability to remove salt from the water could be a problem.Longevity: The filter is sturdy, however depending on usage, it might not last as long as other filtering systems and might need to be changed rather frequently.Thus, these are the criteria it does or does not meet.
