Why is determinism bad? Soft determinism suggests that some behaviors are more constrained than others and that there is an element of free will in all behavior. However, a problem with determinism is that it is inconsistent with society’s ideas of responsibility and self control that form the basis of our moral and legal obligations. […]

What are two characteristics of a compound? Components in a compound are present in a definite proportion. It has a homogeneous composition. Particles in a compound are of one kind. A compound is made up of one or more atoms of the same or different elements. In a compound the elements are present in a […]

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 […]

Is nuclear fusion clean energy? No CO₂: Fusion doesn’t emit harmful toxins like carbon dioxide or other greenhouse gases into the atmosphere. Its major by-product is helium: an inert, non-toxic gas. No long-lived radioactive waste: Nuclear fusion reactors produce no high activity, long-lived nuclear waste. Is nuclear fusion the energy of our future? Fusion power […]

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 […]

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 […]

Can the combination be changed on a safe? It is possible to change the combination on your safe lock. However, depending on whether you have a mechanical or electronic lock will determine the route you’ll need to take to get the job done. Is it cheaper to rekey or replace locks? Rekeying your lock is […]
