Does a 4 stroke engine need mixed fuel? 4 cycle engines do not need oil mixed with the gas to provide lubrication, since it has oil in the crankcase. Two cycle engines have to have oil mixed in the gas to provide the lubrication needed, since there is no oil in the sump. Is 4-cycle […]

Which is better Frye or Daubert? Under Frye, the scientific community is essentially the gatekeeper determining evidence admissibility. Using the strict standard, if the scientific community finds a method or theory acceptable, the court must admit the evidence. While Frye offers a bright line rule, Daubert provides courts with flexibility. What is the main difference […]

How many jelly beans are in a 2 pound bag? 49 How many jellybeans can fit in a Mason jar? Ball 16 oz Pint Mason Jar outer dimensions are 5.2 height by 3.2 diameter – which could hold approximately 390 jelly beans. Ball 32 oz Quart Mason Jar outer dimensions are 6.9 height by 3.9 […]

What is the L quantum number? The angular quantum number (l) describes the shape of the orbital. Orbitals have shapes that are best described as spherical (l = 0), polar (l = 1), or cloverleaf (l = 2). They can even take on more complex shapes as the value of the angular quantum number becomes […]

What is a Si number? The SI base units are the standard units of measurement defined by the International System of Units (SI) for the seven base quantities of what is now known as the International System of Quantities: they are notably a basic set from which all other SI units can be derived. Is […]

How can I measure 5G radiation? Electromagnetic Field (EMF) meters are used to measure RF radiation. With 5G deployments are growing worldwide, the obvious question is – which EMF meters are best suited for measuring 5G signals? Our recommendation for the best EMF meter is the TriField EMF Meter. What is the best radiation detector […]

What is range of normal distribution? The area under each curve is one but the scaling of the X axis is different. Note, however, that the areas to the left of the dashed line are the same. The BMI distribution ranges from 11 to 47, while the standardized normal distribution, Z, ranges from -3 to […]

Which of the following is a postulate of the kinetic molecular theory of gases? As applied to gases, the kinetic molecular theory has the following postulates: Gases are composed of very tiny particles (molecules). The actual volume of these molecules is so small as to be negligible compared with the total volume of the gas […]

Is the tail light the same as the blinker? In many newer cars there is one light bulb per tail light. There are two filaments in each light bulb. One is for your brake light and one is for your turn signal. So when you’re stopped with your turn signal on one filament stays on […]

Who can run faster Boy or girl? Males develop bones faster. Some girls run faster than boys and some boys run faster than girls. Girls may not develop bones as fast as males do because girls are mature and their growth changes at a young age. What should I eat to run faster? Power foods: […]
