Answer:
Wavelength is 10m
Explanation:
To solve this problem, we use the formula for wavelength
Wavelength = wave velocity / frequency
Wavelength = 50m/s / 5Hz
= 10m
Condensation as it is the change of the physical state of matter from gas phase into liquid phase
Answer: A
Explanation:
Hypothesis have to be based on previous knowledge and have to be able to be tested but the problem is most hypothesis can’t be explained so it’s impossible to prove a hypothesis correct because science uses inductive reasoning
Answer:
1.2*10^24 molecules of CF4
Explanation:
the molar mass of cf4 is 88.0043 g/mol
176/88.0043 = 2 moles of CF4
Then multiply by avogadro's number (6.022*10^23) to get the number of molecules
2*6.022*10^23 = 1.2*10^24 molecules of CF4
