Answer:
Carbon Monoxide / Carbon Dioxide / Sulfur and Nitrogen Dioxide
Explanation:
Answer:
1.58×10² nm
Explanation:
Given data:
Frequency of light = 1.90 ×10¹⁵ Hz
wavelength of light = ?
Solution:
Speed of light = wavelength × Frequency
Speed of light = 3×10⁸ m/s
3×10⁸ m/s = λ × 1.90 ×10¹⁵ Hz
Hz = s⁻¹
λ = 3×10⁸ m/s / 1.90 ×10¹⁵s⁻¹
λ = 1.58×10⁻⁷ m
meter to nm:
1.58×10⁻⁷ m ×10⁹ nm/ 1m
1.58×10² nm
It will Rise/Float to the surface/top.
Answer:
Independent: The amount of vinegar
Dependent: The dye result on the egg
Controlled: The type of eggs, the size of jars, the dye tablet, how much she stirs, etc.
Explanation:
The independent variable is what is being changed, which in this case, is the amount of vinegar being added to each jar. The dependent variable is what is being measured or observed. Kesha is looking for what happens to the egg when she adds more vinegar with the dye. Lastly, there could be a couple of controlled variables. Like, the dye tablet, the size and brand of the eggs, the types of jars, how long she stirs each egg, and so on. The controlled are just variables kept constant so that any result observed is because of one singular change, the independent variable.
