<h3><u>Answer;</u></h3>
C. 352.6 m/s
<h3><u>Explanation;</u></h3>
Velocity of sound is dependent on temperature. An increase in temperature, increases the velocity of sound.
To calculate the velocity of the sound wave, we use this formula:
V = 331 + [0.6*T]; Where V is the velocity and T represents temperature.
When the temperature is 36 degree Celsius, we have
V = 331 + [0.6 * 36]
V = 331 + 21.6 = 352.6
Therefore,
V = 352.6 m/s.
Answer:
Carbonates are widely used in industry, such as in iron smelting, as a raw material for Portland cement and lime manufacture, in the composition of ceramic glazes, and more.
Answer:
6 and 3
Explanation:
"Juanita begins to factor an expression as shown.
x² + 3x − 18 = (x + _) (x − _)
What numbers should be placed in the boxes from left to right?"
Use AC method to factor.
1 × -18 = -18
Factors of -18 that add up to 3 are +6 and -3.
The factors are x + 6 and x − 3.
Answer: 92mg of ethyl alcohol
2 milli molar of ethyl alcohol means 2 milli mole glucose for 1 liter of water. Since we want to make 1L of solution, then the amount of ethyl alcohol needed is: 2 milli mole/l x 1l= = 2 x 10^-3 mole
Ethyl alcohol molecular weight is 46g/mole, then 2 mili mole of glucose is= 2x 10^-3 mole x 46 grams/mole= 92 grams x 10^-3= 92mg
