kaheart [24]

Answer:

A.  Nuclear reactors increase thermal pollution

Explanation:

From the analogy provided in this context, we can vividly see that the author is suggesting that the use of nuclear energy causes thermal pollution.

  • Nuclear energy is an alternate energy source as identified in the text.
  • Since a huge amount of heat energy is generated and they are not all used up, they are released into the ecosystem.
  • The earth is usually depicted as heat reservoir.
  • Increased release of heat to the environment will cause thermal pollution.
  • This increases the ambient temperature of water and degrades it.

Scientist are studying an 500g. Sample of a radioactive element. Which has an annual decay rate of 11%. How many grams of the sa
gtnhenbr [62]

Nothing

Explanation:

Mass of the sample = 500g

Decay rate per anum = 11%

Unknown:

Mass of sample remaining after 10yrs = ?

Solution:

  This is a simple percentages problem;

The radioactive sample loses \frac{11}{100 } x 500g of sample per year;

  this is a loss of 55g per year;

In 10years time, the sample would have lost 10 x 55g = 550g of element.

Since our sample is not up to 550g, then no amount of sample will remain after 10yrs.
