Give me right solution. Last time I was recieved wrong solution.. please read the question carefully and give me answer according to the question
How and why does nuclear fusion happens
The US had 264 billion barrels of oil in reserve at the end of 2019. Us annual energy consumption is 1.0 x 1020 joules and energy released by burning a liter of oil is 1.2 x 107 joules. How long can the US run on its reserves? Use the conversion 1 barrel = 159 liters.

- Carbon-14 is radioactive while Carbon-12 is stable. In your body, the ratio of C-14 to C-12 is for every 10,000 C-14 atoms, there are 1 trillion (1,000,000,000,000) C-12 atoms. This is the normal ratio for livings things. In a piece of a sabre-tooth tiger bone, a scientist finds there are only 625 C-14 atoms for every 1 trillion C-12 atoms.How old is the sabre-tooth tiger bone? The half-life for Carbon-14 is 5730 years.arrow_forward19:21 Sun 11 Apr * 55% PHY131&PHY154_GRA2.pdf 5 of 9 Simplifying and taking natural logs on both sides of the equation then brings us to In 2 = kT1/2 (4) Use equation 4 and your value for k to calculate another value for T½.
