Aug 12 2021 As it jumps so often actual impact on WiFi will be highly variable making such scenarios rather hard to troubleshoot Worst case your WiFi access point will automatically change the channel to avoid the interference a misguided strategy as Bluetooth will hop through all the channels that are used for WiFi anyway and this may cause

Jan 04 2021 Bullets can be designed to expand by making them hollow at the pointed end and after impact they expand and squash down into a shape that looks like a button mushroom thats why deforming bullets are called hollowpoint or mushrooming bullets DumDum bullets is another common name for them taken from the place in India where they were

While gravel can be used in concrete and is commonly seen in rough structures as a basic building block it is more common for a fine type of sand to be used for slurry to keep the mixture as pourable as possible while still retaining some form of thickness It also helps the concrete from cracking during the shrinking phase of the curing
