Melt spinning of polymers involves the forcing of polymer melt through spinnerettes (fine holes) into an atmosphere kept at a temperature lower than the melting point of the polymer, which causes the fine diameter polymer melt to harden into filaments. Melt spinning is not used in case of the __________ fibres.
In case of wet spinning of polymers, the polymer solution is forced through spinnerates into, a coagulating bath to give a filament form. Wet spinning is not used in case of the __________ fibres.
At anaphase stage of mitosis in plant cells, interzonal of the spindle fibres gets transformed into
In case of dry spinning of polymers, the polymer solution in a volatile solvent is forced through the spinnerates into a warm air chamber, where the solvent evaporates leaving behind the polymer in the filament form. Dry spinning is used for __________ fibres.
Strain gage uses an electrical conductor wire, which when elastically stretched increases in length and reduces in diameter. Both these dimensional changes result in __________ in the electrical resistance of the wire.

10 cm লম্বা ও 0.5 cm ব্যাসার্ধ বিশিষ্ট একটি তামা ও একটি লোহার তারকে জোড়া লাগিয়ে দৈর্ঘ্য 20 cm করা হল। জোড়া লাগানো তারটিকে বল প্রয়োগ করে লম্বা করা হল। লোহার ইয়ংয়ের গুণাঙ্ক তামার ইয়ংয়ের গুণাঙ্কের দুইগুণ হলে লোহার দৈর্ঘ্য বৃদ্ধি ও তামার দৈর্ঘ্য বৃদ্ধির অনুপাত কত? ( A steel and a brass wire, both having 10 cm length and 0.5 cm radius, are joined together making the total length of the combined wire 20 cm. The combined wire is stretched by applying a force. If the Young's modulus of steel is twice as much as that of brass, what will be the ratio of the extension of steel to the extension of brass?)
