Answer : B is the heaviest puppy amongst all.
Explanation : There are three comparisons shown in the figure, out of which B is assumed to be heaviest amongst all on the basis of following assumptions.
When weighing A and C puppy, A was found to have lighter weight than C. So, in this case C is the heavier puppy.
In second case, when C and D are weighed, both are found to be equal in weight.
Then last comparison was with B and D puppies where, D was observed to be of light weight and B proved to be the heaviest.
Therefore, the conclusion is that B is the heaviest puppy in comparison with rest others.
The energy of moving matter is called kinetic energy. Scientists think that the particles of all matter are in constant motion. In other words, the particles of matter have kinetic energy. The theory that all matter consists of constantly moving particles is called the kinetic theory of matter.
- If particles do not have enough kinetic energy to overcome the force of attraction between them, matter exists as a solid.
- If particles have enough kinetic energy to partly overcome the force of attraction between them, matter exists as a liquid.
- If particles have enough kinetic energy to completely overcome the force of attraction between them, matter exists as a gas.
The aquifer which will be most effective in purifying polluted ground water is AN AQUIFER COMPOSED MAINLY OF SAND.
An aquifer refers to a zone of permeable rock strata which transmit ground water freely. An aquifer must be permeable and porous. Ground water can be extracted from an aquifer by using a water well.
