Which is better VHF or UHF?
Which is better VHF or UHF? VHF radios are suited for long distances in and outdoor use. UHF radios operate at a higher frequency. This makes them ideal for wireless communications that need to penetrate through buildings, walls, or concrete. UHF radios are suited for indoor communication solutions, where obstacles are easily penetrable. Does digital […]

Does foil insulation need an air gap?
Does foil insulation need an air gap? Radiant barrier foil has a 97% reflectivity, basically it’s only letting about 3% of that heat pass through. You MUST have an air gap in order to get either the emissivity quality or the reflectivity quality that you’re looking for, otherwise the foil will not work as a […]
Can you overcharge an e-bike battery?
Can you overcharge an e-bike battery? Ebike batteries should not be overcharged. Doing so can shorten the battery’s lifespan and can cause it to overheat, which may eventually make it unusable.

What are some factors that affect thermal energy transfer?
What are some factors that affect thermal energy transfer? Factors that affect rate of heat flow include the conductivity of the material, temperature difference across the material, thickness of the material, and area of the material. Different materials have greater or lesser resistance to heat transfer, making them better insulators or better conductors. Does the […]
How did Pangea split?
How did Pangea split? Scientists believe that Pangea broke apart for the same reason that the plates are moving today. The movement is caused by the convection currents that roll over in the upper zone of the mantle. About 200 million years ago Pangaea broke into two new continents Laurasia and Gondwanaland. Which era did […]
Which color model is best suited for human interpretation?
Which color model is best suited for human interpretation? The HSI Color Model HSI stands for hue, saturation, intensity. This model is interesting because it can initially seem less intuitive than the RGB model, despite the fact that it describes color in a way that is much more consistent with human visual perception. What does […]
