Filtration is used to separate large particles but this process does not provide pure solutions as some impurities still remain in the solution. On the other hand, distillation helps in the formation of pure water as it removes the impurities from the water or solution.
Answer:
<em>»</em><em> </em><em>λ </em><em>=</em><em> </em><em>0</em><em>.</em><em>0</em><em>2</em><em>m</em>
Explanation:
Given :
Velocity of the wave {v}= 12 m/s
Frequency {f} = 600 Hz
Apply Wavelength formula :
• 
→ λ = 
→ λ = 
→ λ = 0.02m
Answer: Each trial was repeated several times during the experiment.
A scientific design refers to a scientific plan or methodology, which needs to be followed to perform a experiment so as to obtain accurate and appropriate result matching with the situation of the hypothesis. Each trial was repeated several times during the experiment best describes an experiment that had a good scientific design because trials in an experiment brings either concordant or consistent results or inconsistent results. The concordant results suggests that the methodology applied is correct, and inconsistent results show that methodology applied is incorrect.
