An element has a half-life of 30 years. If you start with 10g of this element, how many grams of this element would remain after

drek231 [11]

After two half-lives or 60 years, 7.5 g of the element will be left.

<u>Explanation:</u>

In simple words, Half-life can be defined as the amount of time needed for a quantity to fall to half its value as contained at the beginning of the time period.
In this problem the half-life of the element is thirty years, then after thirty years half of the sample would have decayed and half would be left as it is.
After thirty years (The first half-life ) 30 /2 = 15 g declines and 15 g remains disappeared.
And after another sixty years (The two half-lives) 15 /2 = 7.5 g declines and 7.5 g remains disappeared.
After two half-lives or 60 years, 7.5 g of the element will be left.

Suppose that an adult black bear adds 50 pounds of fat in order to survive while hibernating through the winter. how much glycog

NemiM [27]

Answer: The correct answer would be 112.5 pounds

Explanation:

Let us first covert the pound into grams. We know that 1 pound is equal to 453.59 grams.

Thus, 50 pound of fat = 50 x 453.59 = 22,679.5 grams.

We know that, 1 gram of fat releases 9 Kcal of energy. Thus, total energy produced by 22679.5 grams = 9 x 22679.5 = 204,115.5 Kcal

Glycogen is carbohydrate thus, it will produce 4 Kcal of energy per gram.

Thus, 4 x C = 204,115.5 (where C is the grams of glycogen)

⇒ C = $\frac{204115.5}{4}$

⇒ C = 51,028.875 grams

Using 1 pound = 453.59 grams, we con convert 51,028.875 grams into pounds:

453.59 = 1

1 = $\frac{1}{453.59}$

51,028.875 = $\frac{1}{453.59} x 51028.875$

= 112.5 pounds

Thus, 112.5 pound of glycogen would be needed to produce the same amount of energy as produced by 50 pounds of fat.
