As of January 2009, the USA has produced 60,000 metric tons of nuclear waste in 60 yesrs of operating 104 nuclear power plants.

goblinko [34]

Answer: a. 0.8 tons p. month.

Explanation:

Given: Total nuclear waste = 60,000 metric tons

Time take = 60 years = 12 x 60 months [ 1 year = 12 months]

= 720 months

Total nuclear power plants = 104

Now , Average waste produced by each plant = $\dfrac{\text{Total waste}}{\text{Time x Number of plants}}$

$=\dfrac{60000}{720\times104}\approx0.8\text{ tons per month.}$

Hence, 0.8 tons p. month is produced by each plant.

So, option a. is correct.

A scientist claimed that he radiocarbon dated a fossilized skull of a dinosaur and found it to be about 63 million years old. Do

Elodia [21]

Answer:Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some could tolerate. After the AOGS-AGU conference in Singapore, the abstract was removed from the conference website by two chairmen because they could not accept the findings. Unwilling to challenge the data openly, they erased the report from public view without a word to the authors. When the authors inquired, they received this letter:

Water flows over Niagara Falss at the average rate of 2,400,000 kg/s, and the average height of the falls is about 50 m. Knowing

liberstina [14]

Answer:

1. 176 × 10^12 W ; 78400000000

Explanation:

Given the following :

Fall rate = 2,400,000kg/s

Average height of fall = 50m

Gravitational Potential of falling water = mgh = mass × acceleration due to gravity × height =

How many 15 W LED light bulbs could it power?

Recall : power = workdone / time

Workdone = gravitational potential energy

Mass of water = density * volume

Density of water = 1 * 10^3kg/m^3

Rate of fow = volume / time = 2400000

Hence,

Power = 1000 * 2,400,000 * 9.8 * 50

Power = 1176000000000

Power = 1. 176 × 10^12 W

How many 15 W LED light bulbs could it power?

1176000000000 / 15 = 78400000000

= 78400000000 15 W bulbs

5. Which are generally less soluble, compounds with chlorate ions or carbonate ions?

Vitek1552 [10]

Answer:

Compounds with Carbonate ions are less soluble than the compounds with Chlorate ions.

Explanation:

The reason is that the compounds with carbonate ions have less attraction between positive and negative charges. (Solvation)
