Answer:
Option (3)
Explanation:
The elasticity property of rock describes how a rock that is subjected to stress undergoes bending and again comes back to its original position. In nature, most of the rocks are non-elastic as they undergo deformation due to the stress acting on them. So the rocks are not always perfectly elastic.
According to Hooke's law, in case of a comparatively small deformations of an object, the displacement that occurs on the rocks or the deformation size that occurs is directly proportional to the amount of load that undergoes deformation.
Hence, the correct answer is option (3).
Short scale farming and large scale farming are the two types of Agriculture based on the availability of land.
The two tools used are:
- A relationship existence between a galaxy's distance from Earth and also that of its speed.
- The findings in the 1960s of the presence of cosmic microwave background radiation.
<h3>What evidence is collected by each tool?</h3>
The evidence to support the big bang are:
- There was found to be some red shifts of a lot of galaxies which connote that the universe is widening.
- Due to the widening of universe, new elements were formed such as hydrogen, deuterium and others.
- Microwaves were found by orbiting detectors.
Therefore, The two tools used are:
- A relationship existence between a galaxy's distance from Earth and also that of its speed.
- The findings in the 1960s of the presence of cosmic microwave background radiation.
