The main difference between Ordinary Polythene & Biodegradable polythene is:
* Ordinary polythene takes an around 100 + years to degrade...
* Biodegradable/Degradable polythene degrades or biodegrades in around 5 yrs depending on how it's made and how its disposed. However, biodegradation starts in the presence of sunlight, moisture, mechanical stress and/or microorganisms...

No, polythene does not dissolve in water as it is a non-polar polymer and water is a polar solvent. This lack of attraction between the polythene molecules and water molecules prevents it from dissolving.
Polythene acquires a positive charge when rubbed with a cloth due to the triboelectric effect, where electrons are transferred from one material to another. In this case, the cloth tends to lose electrons to the polythene, resulting in the polythene becoming positively charged. The friction between the two materials facilitates this transfer, causing the imbalance of charge. Thus, the polythene ends up with a net positive charge while the cloth becomes negatively charged.
An ordinary transformer uses mutual inductance to transfer energy from one circuit to another, while resonant coupling energy transfer utilizes resonance between the coils to enable more efficient energy transfer. Resonant coupling allows for wireless power transfer over larger distances compared to traditional transformers.
Yes, perspex can become attracted to a polythene rod when rubbed together due to the transfer of electrons between the two materials, resulting in a temporary static charge.
An ordinary magnetic compass points to magnetic north, not to true north. If the difference between the two directions is large and not accounted for, you can get lost.
Nothing.
Biodegradable can be broken down by the earth naturally, non- biodegradable can not.
There is no difference between polythene and polyethylene. Polythene is simply another name for polyethylene, which is a common type of plastic material used in many products such as plastic bags, containers, and packaging.

The difference between a tied grant and an ordinary grant is that a tied grant has conditions and the ordinary grants don't!
Bakelite is a thermosetting plastic, meaning it cannot be reshaped once molded, while polythene is a thermoplastic that can be melted and reshaped multiple times. Bakelite is a poor conductor of electricity, whereas polythene is an insulator. Bakelite is more rigid and heat resistant compared to polythene.
Polyethylene and polythene are the same material. Polythene is a common term for polyethylene in certain countries, particularly in the UK and India. Both refer to a type of synthetic polymer that is widely used in various applications, such as packaging and manufacturing.

The main difference between an ordinary dividend and a qualified dividend is how they are taxed. Qualified dividends are taxed at a lower rate than ordinary dividends, which are taxed at the individual's regular income tax rate.
