2. US imposed 25% tariff on Indian exports. What’s the extra penalty?
Answer : Penalty on Russian oil & weapons imports
The United States has imposed a 25% tariff on all Indian exports to the U.S., effective August 7, 2025 (previously announced as August 1).
In addition to this base tariff, an extra, unspecified penalty has been levied. The penalty is linked to India’s continued purchases of Russian energy (primarily crude oil) and military hardware, which U.S. officials have cited as the primary justification for the added measure.

4. Who developed 1st deep-sea radar
Answer : China
In 2023, a team of Chinese scientists from Xiamen University, led by Professor Shangguan Mingjia, developed the world’s first deep-sea radar-like system using single-photon Raman LiDAR technology. This breakthrough system can detect objects up to 1,000 meters below the sea surface.
Though technically it’s LiDAR (light detection and ranging) and not traditional radar (radio waves), this is considered the first electromagnetic-based deep-sea detection system—earning it the title of the first deep-sea “radar.”
