Why do scientists need to study seismic waves to analyze the interior of the earth and the layers of the earth?

1 answer:

3 0

Geologists use these records to establish the structure of Earth's interior. The two principal types of seismic waves are P-waves (pressure; goes through liquid and solid) and S-waves (shear or secondary; goes only through solid - not through liquid).

How much volume would 0.450 mol CO2 gas occupy?

umka21 [38]

Answer:

10.08 L.

Explanation:

If we assume that CO₂ gas behaves ideally at STP (standard T(0.0 °C) and P(1.0 atm)):

It is known that 1.0 mole of ideal gas occupies 22.4 L at STP conditions.

Using cross multiplication:

1.0 mole of CO₂ gas occupies → 22.4 L.

0.45 mole of CO₂ gas occupies → ??? L.

∴ The volume occupied by 0.45 mole of CO₂ gas = (0.45 mol)(22.4 L)/(1.0 mol) = 10.08 L.

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.
