Which is more abundant K39 K40 OR K41?
K-39 is the most abundant, constituting about 93 % of the atoms in naturally occurring potassium.
How much of a 400-gram sample of K40 is left after 2 half-lives?
After the first half-life, you will have one half of the starting amount. After a second half-life period, you'll be down to one quarter. Of the part that radioactively decays, about 11% of it will decay to 40Ar, and the remainder to 40Ca. Of your total sample of ordinary potassium, only 0.012% will be 40K. The half-life of 40K is about 1.3x109 years.
What is groundsheet made of?
Groundsheets are typically made of materials like polyethylene, polypropylene, or nylon. These materials are durable, waterproof, and provide protection from moisture, dirt, and sharp objects while camping or sleeping outdoors.
Why is the use of hydrogen in plastic?
Hydrogen is used in plastic production because it is a key component in many polymers, such as polyethylene and polypropylene. Hydrogen atoms help form strong bonds with other elements, contributing to the overall stability and structure of plastic materials. Additionally, using hydrogen in plastic production can help reduce the carbon footprint of the manufacturing process.

Is the k40 CB antenna a marine band antenna and if not will it work with a marine band raido?
The K40 will not work as a marine band antenna, as it is "cut" (optimised) for 26-30Mhz. The Marine Band of frequencies is usually found 156-174Mhz.
Will polypropylene rust?
Yes polypropylene will rust because the air is congaus.
