The radiator is next to the triangle, receiving the sound waves and they travel through the radiator up to the other room. She can't hear the sound if the triangle isn't struck near the radiator because the sound waves aren't going through the radiator, and are not able to reach her through the wall. Hope this helps!
The half-life of potassium-40 is about 1.25x10^9, or 1.25 billion, years. it undergoes beta decay and becomes argon-40. Equal amounts would be one half-life, so the sample is also 1.25x10^9 years old.
The Molarity of volumetric flask 1 : 1.26 M
The Molarity of volumetric flask 2 : 0.06 M
<h3>Further explanation
</h3>
Dilution is a process of decreasing the concentration of a solution by adding a number of solvents
Can be formulated
M₁V₁=M₂V₂
M₁ = Initial Molarity
V₁ = Initial volume
M₂ = Final Molarity (after dilution)
V₂ = Final volume (after dilution)
Volume of volumetric flask = 500 ml
