Answer:
48.63 mL
Explanation:
Using Charles's law
Given ,
V₁ = 29 mL
V₂ = ?
T₁ = 25 °C
T₂ = 500 K
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25 + 273.15) K = 298.15 K
Using above equation as:
<u>New volume = 48.63 mL</u>
Answer:
69.7173 u
Explanation:
The abundance of the first isotope is =60.40%
So the abundance of the second isotope =100%-60.40%=39.6%
Atomic mass of first isotope = 68.9257
So the average atomic mass of the first isotope =68.9257×0.6040=41.6311 u
Atomic mass of the second isotope =70.9249 u
So average atomic mass of second isotope =70.9249×0.396=28.086
Now the average atomic mass =41.6311+28.086=69.7173 u

<span>So we want to know which of the following is the best representation of converting potential energy into kinetic energy. The correct answer is C. A roller coaster rounds a curve to climb the next hill. So before he climbed the hill, the roller coaster had kinetic energy which he used to climb to the hill. Then the potential energy he has on the hill can again be transformed into kinetic energy when he will go down hill. </span>
