First use this equation to find the wave speed: vms== =τµ/ 0.4/ 0.001 20 / Then use the equation for solving frequency of a wavelength, and solve for wavelength λ = v/f = 20/100 = .2 m = 20 cm.
18 x 10^23. This is the answer because there are 6.022 x 10^23 atoms of carbon and 12.044 x 10^23 atoms of oxygen in one mole of CO2, if you combine them, you get 18 x 10^23
Answer:
two atom of hydrogen,two atom of oxygen
C - bc as the water boils the cold water particles melt and become the hot water particles!
