I had to look for the options and here is my answer:
Given that a guitar string has a basic frequency of 500hz, the frequency that can be set for this into resonant vibration would be 1500 Hz. The resonant vibration here is necessary in musical instruments because it delivers a vibrating system which leads to a higher amplitude at a particular frequency.
Water vapor and carbon dioxide
Answer:
Mass of the solution = 54.75 g
Explanation:
Mass of solid dissolved = 4.75 g
Mass of the solution = Mass of solid dissolved + Mass of water.
Mass of water = Volume x Density
Volume = 50 mL = 50 cm³
Density = 1 g/cm³
Mass of water = 50 x 1 = 50 g
Mass of the solution = 4.75 + 50 = 54.75 g
Answer:
It's nitrogen. Specifically, this is the alpha emission of an N-15 isotope.
