We know the equation for calculation of speed of sound at temperature:
<span>v = 331 m/s + (0.6 m/s/C) * T
</span>Here, T = 30 C
v = 331 m/s + (0.6 m/s/C) * 30 C
v = 331 m/s + 18 m/s
v = 349 m/s
In short, Your Answer would be 349 m/s
Hope this helps!
Answer:
52.5 g of the salt
Explanation:
From the question given above, we were told that concentration of the mixture that is needed can be obtained as by dissolving 35 g of salt in 1000 mL of water.
Thus, we can obtain the mass of the salt needed to make 1500 mL of the salt water mixture as follow:
35 g of salt dissolves in 1000 mL of water.
Therefore, Xg of the salt will dissolve in 1500 mL of water i.e
Xg of salt = (35 × 1500)/1000
Xg of salt = 52.5 g
Thus, 52.5 g of the salt is needed to make 1500 mL of the salt water mixture.
the answer is spiral galaxies
Answer:
Heat capacity is the ratio of the amount of heat energy transferred to an object to the resulting increase in its temperature. Molar heat capacity is a measure of the amount of heat necessary to raise the temperature of one mole of a pure substance by one degree K.
