Select the correct statement(s) A Microbial experiment show the pre-existing advantageous mutations when selected will result in the observation of new phenotypes Over few generation this would result in speciation B Neanderthal fossils represent a human relative C In 1938, a fish caught in South Africa happened to be a coelacanth (lobe fins) which was thought to be extinct These animals evolved into the first amphibian living on both land and water D Lichens can be used as water pollution indicators E Alfred Wallace, a natur st, who worked in Malay Archepelago (present Indonesia) has also come to similar conclusion on natural selection as reached by Darwinism

A 20 capacitor is connected to 45 V battery through a circuit whose resistance is 2000 What is the final charge on the capacitor?
We know that in steady state the capacitor behaves like as an open circuit , capacitor will not pass the current.
So, the potential difference across the capacitor = 45 V
Hence , the final charge on the capacitor is
