Q:Im looking for a place that sells sheets of Lenticular Len's. Its those plastic sheets that people use as decoders.

Lenticular Sheet

Q:A large horizontal flat sheet of insulating plastic (near the earth's surface) carries a total charge +22MC distributed over the area of the sheet (1.1m^2). A dust mote carries charge +3.5mc and has a mass of 2.2x10^-4 kg. What is the acceleration when it is just above the sheet of charge? Don't neglect gravity.

The force exerted by the sheet is F=E*q where E=6/(2*e0) 6 charge density in this case 6=q/A=20*10powered6 C/m2 e0=8,85*10powered12 C2/(N*m2) (n2 means n powered 2) a*m+E*q=m*g a=(m*g - q*6/(2*e0))/m if g=9,8 m/s2 then a=9,79998 m/s2

Q:I'm trying to learn Gauss's law and I'm having trouble with these two questions.1. Consider a long cylindrical charge distribution of radius R = 17 cm with a uniform charge density of ρ = 17 C/m3. Find the electric field at a distance r = 35 cm from the axis. I know E= 2k_e*(lamda/r), but the question gave rho, which is confusing me.2. A 12 g piece of Styrofoam carries a net charge of -9.1 ?C and floats above the center of a large horizontal sheet of plastic that has a uniform charge density on its surface. What is the charge per unit area on the plastic sheet? I got to the point where I had the charge density = -mg(epsilon_0)/q, but apparently that is not the correct answer, and I don't know where to go from here.Any help is appreciated. Thanks :)

If the sector at distance R is E0, then it is likewise E0 at 2R. the sector of a limiteless airplane of fee has an identical importance everywhere (?/2?). This properly regular consequence of Gauss's regulation is defined in all difficulty-loose text textile books.

Q:I'm curious how plastic sheets/boards are made. The kind that may possibly be found at places like Home Depot.. I have an inkling that the sheets are extruded and cut into boards.. but I need a confirmation of this process. It would help greatly!!Is there a site that can explain this process?Any advice helps and is greatly appreciated. THANKS!! :)

Plastic sheets / tubes of longer length are produced by extruding. Smaller sizes by moulding.

Q:I need some to place at the back of my garden, not sure where to go and i don't want to have to pay to much, i don't mind having to wait for it to be delivered or a store would do. Thanks !

I'm almost certain that all homecenters carry material used for things like roofing a carport. They probably carry it in clear and just about every color.

Q:Even in my own garden, I saw that plastic sheets were placed just below a small layer of topsoil and mulch where some shrubs and flowers were being grown. What is this layer of plastic used for?And if I wanted to suppress an invasive species (English Ivy) with this layer of plastic, would it work?

Landscaper's Fabric? There's also some type of weed-stopping material. The Landscapers Fabric is used to keep out bugs and animals from coming up underneath and digging down. I'm not sure about the Ivy, it depends on if its a runner or not.

Q:Can I use wallpaper paste to stick gravel to plastic sheeting?I want to make, as cheaply as possible, a Sempervivum roof for a bee house in my garden and thought I could us a plastic sheet, gravel stuck on that, then earth and the plants.What's the easiest and less smelliest (bees don't like smells) glue I can use? Will wallpaper paste do?Thanks for reading.

Wallpaper paste will not work in this application. It will turn to mush again as soon as moisture gets to it. Most adhesives that apply in liquid form will not work well, and almost all will have smell that remains for some time One adhesive that would work well both on plastic sheeting, have virtually no smell, and will remain solid under dirt is hot glue, but application is time-consuming, and you will have to be careful with the application temperature, as it has to stick onto the plastic, but not melt through it. A heavy-grade plastic sheet will be needed/ You have some choice in the melt points of the glue stick and can ask at the store about the lowest melt sticks they have. . The easiest solution to this might be a small craft-store glue gun and buy the sticks from them (or a dollar store) as they only use glue sticks that have a low melt point Before beginning your main work, practice applying the glue on a spare part of the sheeting and see how quickly you can work with it,

Q:My basement is filled with the stuff but it's almost 10 years old by now.

Q:Can plastic sheets be used for sound barriers in construction?

Yes, plastic sheets can be used as sound barriers in construction. They are lightweight, easy to install, and can effectively reduce noise transmission when properly designed and installed.

Q:Can plastic sheets be used for protective covers in industrial settings?

Yes, plastic sheets can be used for protective covers in industrial settings. They are often chosen due to their durability, resistance to chemicals and moisture, and their ability to provide a barrier against dust, debris, and other potential hazards. Plastic sheets are commonly used to protect machinery, equipment, and surfaces in industrial environments, helping to extend their lifespan and maintain their functionality.
