When a wire is stretched its volume stays the same, so the length must grow in the same ratio as the cross-sectional area shrinks.

In parallel the equivalent resistance is always smaller than the smallest single resistor, so here it falls below 1 Ω. For resistors in parallel, 1/R = 1/R1 + 1/R2 + 1/R3 = 1/1 + 1/2 + 1/3 = 11/6, so R = 6/11 Ω, about 0.55 Ω. Each extra parallel…

Dhaka, famous for its fine muslin, lost its trade and population after the mid-eighteenth century as the East India Company's rule and cheap British cloth destroyed its textile industry.

SONAR sends out pulses of high-frequency sound, above 20 kHz, which travel well through water and bounce back from objects.

Petroleum ether is a solvent and petroleum jelly is spread on metal surfaces as a protective coating, while the uses given for petroleum wax and white spirit have been swapped around.

The ship took part in the ninth edition of the India-Brazil-South Africa Maritime Exercise, and its Commanding Officer spoke at the closing ceremony at Simon's Town, where he described such exercises as a platform that turns long-standing diplomatic ties into usable naval cooperation.

The closing ceremony of IBSAMAR IX was held there on 20 October 2026, rounding off ten days of joint activity in a harbour phase and a sea phase.

IBSAMAR stands for the India-Brazil-South Africa Maritime Exercise, and the ninth edition brought the navies of these three countries together before concluding at Simon's Town in South Africa.

At the outreach the Air Force listed four areas needing focused attention: indigenous propulsion, autonomous software, resilient navigation and standardised interfaces, all of them meant to cut dependence on external sources and strengthen the domestic defence ecosystem.

Around 100 representatives of drone companies and allied industry partners attended, which the Air Force treated as a measure of its growing engagement with the unmanned ecosystem in the country.

The roadmap was released there on 14 September 2026, and the Industry Outreach Programme of 21 October 2026 at Vigyan Bhawan in New Delhi was built on it, with the roadmap booklet distributed to industry partners on that day.
