Answer:
a) A suspended floor is a ground floor with a void underneath the structure. The floor can be formed in various ways, using timber joists, precast concrete panels, block and beam system or cast in-situ with reinforced concrete. However, the floor structure is supported by external and internal walls.
b) Soil exploration consists of determining the profile of the natural soil deposits at the site, taking the soil samples and determining the engineering properties of soils using laboratory tests as well as in-situ testing methods
c) Bulking in sand Occurs When dry sand interacts with the atmospheric moisture. Presence of moisture content forms a thin layer around sand particles. This layer generates the force which makes particles to move aside to each other. This results in the increase of the volume of sand.
d) In a nutshell, bearing capacity is the capacity of soil to support the loads that are applied to the ground above. It depends primarily on the type of soil, its shear strength and its density. It also depends on the depth of embedment of the load – the deeper it is founded, the greater the bearing capacity.

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]

Technician A says that a 3x5 card should be held against the oil fill opening if the positive crankcase ventilation system is working correctly. Technician B says that if a PCV valve rattles then it’s working properly. Who is correct?
Answer:
Both Tech A&B are correct
Explanation:
In the given case, one can conclude that the technicians, A is correct and B is incorrect. The correct option is A.
What is PCV valve?Positive crankcase ventilation is referred to as PCV. Your engine's crankcase, which is where your motor oil is stored, is found there. Waste gases are created when gasoline is burnt in your engine and are primarily released through your exhaust system.
A rough idle, sluggish acceleration, or increased oil consumption may occur if the valve doesn't open and close on schedule or if any component of the system becomes clogged.
Problems with the PCV valve are frequently misdiagnosed since faulty spark plugs are frequently the source of rough idling.
If a PCV valve rattles then it should definitely be replaced. This means only technician A is correct.
Thus, the correct option is A.

Evaluate this design by describing the criteria it does or

Answer:
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.

Shops can mix refrigerants
Answer:
False
Explanation:
The statement "Shops can mix refrigerants" is false.
What are refrigerants?Refrigerants are the chemicals that are used in the refrigerator's cycle of the air conditioner. They are fluid. Examples of refrigerants are CFC, HCFC, FC, ammonia, etc.
They are changed to form a phase of liquid to gas and gas to liquid. They are their transition stages. There are four types of refrigerants. They are Evaporative Cooling, Mechanical-Compression Refrigeration Systems, absorption, and thermoelectric.
Inadequate system pressures and temperatures can be brought on by mixed refrigerants. This may lead to inadequate cooling of the compressor, potential compressor damage, inadequate cooling, and metering device malfunction.
Thus, the statement is false regarding shops can mix refrigerants.
