Two sound waves are emitted from identical sources at the same time. They each travel a distance of 10 m, but one wave reaches t
he destination faster than the other. What can you conclude about the two waves?
2 answers:
Answer:
Faster one has a lower frequency and higher wavelength.
Explanation:
The waves have properties such as frequency and wavelength. If the distance they travel is the same but one wave is faster than the other one, the faster wave must have a lower frequency and higher wavelength as it can be seen in this graph from Encyclopedia Britannica.

Answer:
Molecular weight of the compound = 372.13 g/mol
Explanation:
Depression in freezing point is related with molality of the solution as:
Where,
= Depression in freezing point
= Molal depression constant
m = Molality
m = 0.26
Molality =
Mass of solvent (toluene) = 15.0 g = 0.015 kg
Moles of compound = 0.015 × 0.26 = 0.00389 mol
Mass of the compound = 1.450 g
Molecular weight =
