Answer:
Yosef hypothesis could be stretching of rubber band depends on rubber band's width. It is difficult to stretch a wider rubber band in comparison to a narrow band.
Explanation:
Width of rubber band affect how easily it can be stretched. It is found that it is difficult to to stretch a wider rubber band in comparison to a narrow band because when rubber band is narrow less molecules will be there along its width and hence less restoring force will be there so rubber can be easily stretched. On the other hand when the rubber band is wider it means more molecules are there along its width and hence more restoring force will be there while stretching so it will be difficult to stretch a wider rubber band.
Answer:
True
Explanation:
When a nuclear power plants ends its operating life, it is necessary to dispose correctly all the radioactive material left from the operations of the power plant.
In fact, apart from the fuel rods (which contain the uranium that is the fuel of the nuclear reactions), other materials of the core (such as the vessel) becomes radioactive due to the prolonged exposure to the products of nuclear reactions in the core.
As a result, all these materials remain radioactive for very long time (hundreds or thousands of years). It is therefore important to dispose them correctly, in proper sealed containers which are able to shield the radiation emitted by these radioactive element (alpha, beta and gamma radiation).
Therefore, "waste from nuclear power plants must be disposed of in radioactively shielded storage containers" is a correct statement.
