ANSWER: C

ANSWER: B

ANSWER: A

ANSWER: A

• ISRO successfully completed the CE20 E13 engine hot test for the Gaganyaan qualification and 22-tonne thrust qualification.

• The engine developed by the Liquid Propulsion Systems Centre (LPSC), Valiamala was tested at ISRO Propulsion Complex (IPRC), Mahendragiri, Tamil Nadu.
• The CE20 engine is a vital component, serving as the powerhouse of the Cryogenic Upper Stage (CUS) responsible for propelling the upper stage (C25) of the Launch Vehicle Mark-3 or LVM3 vehicle.
• It has demonstrated its capability by successfully operating at a thrust level of 19 tonnes in six successive LVM3 missions, including the Chandrayaan-2, Chandrayaan-3, and two commercial OneWeb missions.
• The CE20 engine hardware referred to as E13 was selected for both Gaganyaan qualification and 22-tonne thrust level operations.

ANSWER: A

ANSWER: C

• IndianOil has unveiled India’s first green hydrogen-run bus that emits just water.
• IOCL will produce close to 75 kg of hydrogen by splitting water using electricity from renewable sources.
• This hydrogen will be used to power two buses which will ply across the national capital region for trial runs.
• IOC’s R&D Centre at Faridabad is producing green hydrogen for the pilot run.
• Four cylinders with a capacity of 30 kg can run the buses for 350 km.
• It takes 10-12 minutes for the four tanks to fill.

HYDROGEN AS FUEL

• Hydrogen when burnt emits only water vapour as a by-product.
• With three times the energy density and the absence of harmful emissions, hydrogen shines as a cleaner, more efficient choice to meet the energy requirement.
• As much as 50 units of renewable electricity and 9 kg of deionized water are needed for the production of one kilo of green hydrogen.
• Hydrogen can be used as a fuel for fuel cells.
• The global demand for hydrogen is expected to increase by four to seven times to 500-800 tonne by 2050.

ANSWER: A

• Kole wetlands, an internationally important Ramsar site of high value biodiversity, has been facing the threat of alien invasive species.
• Cabomba furcuta, popularly called as Pink Bloom due its massive flowering, has been a new threat to the kole fields, in addition to water hyacinth and Salvinia molesta.

ABOUT CABOMBA FURCUTA

• A native of central and south America, Cabomba furcuta was brought to Kerala as an aquarium plant and has escaped to the wild.
• The submerged perennial aquatic plant grows in stagnant to slow-flowing freshwater.
• The fast growing Cabomba is a visual treat but becomes a potential outspread in water bodies by active stem propagation, hindering penetration of light into the water.
• Cabomba, which requires a large quantity of oxygen for its growth will choke water bodies and drainage canals.
• It causes decline in diversity of native aquatic plants and causes economic losses by affecting yield of freshwater fishes.
• The key to controlling the species is to mechanically remove them from the waterbody and dry them in terrestrial spaces, the team notes.

ANSWER: D
