What is a strong relationship between two variables? A correlation coefficient measures the strength of that relationship. Calculating a Pearson correlation coefficient requires the assumption that the relationship between the two variables is linear. The relationship between two variables is generally considered strong when their r value is larger than 0.7. What is the relationship […]
What is the process of incineration?
What is the process of incineration? Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Incineration and other high-temperature waste treatment systems are described as “thermal treatment”. Incineration of waste materials converts the waste into ash, flue gas and heat. What garbage is burned in the incinerator? […]
In what year was on-board diagnostics II Obdii systems enacted nationwide?
In what year was on-board diagnostics II Obdii systems enacted nationwide? 1996 Which operating mode of the OBD II system shows current data? Mode $02… Mode $02 provides the data stored at the time the fault was detected by the OBD-II and when the OBD-II system turned on the MIL. Mode $02 output only shows […]
What is logic block in FPGA?
What is logic block in FPGA? In computing, a logic block or configurable logic block (CLB) is a fundamental building block of field-programmable gate array (FPGA) technology. Logic blocks require I/O pads (to interface with external signals), and routing channels (to interconnect logic blocks). Why is FPGA Field-Programmable? A field-programmable gate array (FPGA) is an […]

How do you calculate backfill on a retaining wall?
How do you calculate backfill on a retaining wall? Multiply the length of the wall by the desired height, then divide this number by 81 to determine the amount of backfill gravel needed. Add the backfill amount to the base amount to determine the total cubic yards of gravel necessary for completing the wall. How […]
Is ammonia heavier than air?
Is ammonia heavier than air? Anhydrous ammonia gas is lighter than air and will rise, so that generally it dissipates and does not settle in low-lying areas. However, in the presence of moisture (such as high relative humidity), the liquefied anhydrous ammonia gas forms vapors that are heavier than air. Do ammonia fumes rise? Most […]
Why does oxygen have a charge?
Why does oxygen have a charge? Oxygen is more electronegative than carbon which attracts the electrons to them usually giving it a negative charge. How will an atom get a charge of +2? A normal atom has a neutral charge with equal numbers of positive and negative particles. Ions are atoms with extra electrons or […]
How does an air powered car work?
How does an air powered car work? For compressed-air cars, the power plant’s electricity is transmitted to a compressor, which mechanically compresses the air into the car’s tank. The car’s engine then converts the compressed air to mechanical energy. What energy does wind have? kinetic energy Is there a car that runs on air? In […]
What are the forms of iron ore?
What are the forms of iron ore? Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits. What are the 4 types […]
