Answer:
c. 10-10 seconds
Explanation:
To be able to penetrate very deeply into the matter we need to generate very high energies, we need somehow very energetic particles that can test very small distances inside the matter. And for that you have to build particle accelerators. For example, a proton is a constituent of the atom, the nucleus of the hydrogen atom. These particles accelerate in an accelerator until they reach speeds very close to the speed of light and the highest energies ever before reached by a man-made instrument on earth.
Then with these high energies we test the small distances, the deepest structure of matter and what is interesting is that by producing these enormous energies in a laboratory and in a tiny microscopic region of space we are reproducing the conditions that were present in our universe primitive. Actually in fractions of seconds after the Big Bang.
Technology is enough for us today to reach 10 ^ (- 10) seconds after the Big Bang (ie 0.0000000001 seconds).
The correct answer is A. chemical fertilizers and pesticides.
Organic farming is a method of farming in which crops are cultivated in such a way to keep the soil alive and in good health by using organic waste of crop, animal and farm waste and aquatic waste. Other biological materials such as beneficial microbes are added to the crop field which release nutrients to the crops. Use of chemical fertilizers and pesticides should be limited as these are non-biodegradable and cause harm to the ecosystem and soil.
