<u>Radioactive</u> naturally breaks down by shooting away parts of their atoms
<u>Explanation:</u>
The isotopes which are not in balance like the neutrons and protons of those isotopes are not in balance with each other are known as radio active. But these radio active come back to the state of a normal isotope when the energy which is extra in them gets released and stabling down to a normal isotope.

They are just nervous and don't want to be embarrassed in front of all those people they are telling them to
Answer: Diminishing returns to physical capital
Explanation: The relationship between the amount of capital per worker and average labor productivity, which shows positive correlation for developing and less developed countries and a weaker relationship for developed countries can best be explained by the law of diminishing returns which suggests that as a country continues to increase its human and physical capital, marginal gains to economic growth will begin to diminish.
Diminishing returns to physical capital can be explained as the decline or smaller increase in productivity observed for every successive increase in physical capital when human capital per worker and technological level is fixed.
Developed countries thus possess higher technological and economic development than less developed and developing countries, hence the observed correlation.
