non coorporation movement was started by mahatna gandhi in 1920
to drive british out of the country.

it was nothing but declaration of peace and non -violence war against British.
Result -
non-cooperation movement aparently failed.but it also benefited the indian economy. Indian mill-owners earned a good profit due to the programme of boycott. The import of sugar from England decreased considerably. The import of British cotton-goods decreased from Rs. 6.7 crores to Rs. 2.8 crores within a period of six months. Likewise, the import of iron decreased to 50%

Explanation:

Answer: It will take 22920 years to decay 112.5 g of 120 grams.

Explanation: Radioactive decay follows first order kinetics.

Half-life of carbon-14 = 5730 years

\lambda =\frac{0.693}{t_{\frac{1}{2}}}=\frac{0.693}{5730}=1.209\times 10^{-4}year^{-1}λ=
