Another pendulum clock of same length, but of double the mass of the bob is lifted to another height where the gravitational acceleration is $$\frac{g}{2}$$. The time period of the second pendulum would be (in terms of period T of the first pendulum)

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ the passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. A range of extreme weather events in 2018 — think extreme rainfall, floods, landslides, cyclones, and heatwaves — claimed 2,081 lives in India, more than181 other countries that featured on a new global climate risk index. P. These rankings were recently released by the non-profit Germanwatch in a report titled The Global Climate Risk 2020, the results of which are calculated based on average values over a 20-year period, i.e., 1998 to 2018. Q. In terms of economic losses, India ranked second. Overall, per this index, in 2018, India was the fifth-worst-hit country by climate change, pushed up by nine ranks from 2017, when it was the 14th. R. Talking of rainfall-related calamities such as cyclones, floods, and landslides, as many as 6,585 people have died in India in the three-year period leading up to July 2019. S. In 2018, India was affected by a range of extreme weather events including floods in Kerala, tropical cyclones like Gaja and Titli, as well as a prolonged heatwave, all of which have collectively propelled India to the top position. 6. “This is a clear signal that climate change impacts are happening, and increasing everywhere, including in developed countries.
