The correct answer is "wavelength".
In fact, this is exactly the definition of wavelength: in a wave, the wavelength is defined as the distance between two succesive crests or two successive troughs, therefore the correct answer is
D) wavelength.
Answer:
Mass = 27.6 grams
Explanation:
Given the following data;
Density of ice = 0.92g/cm³
Volume = 30cm³
To find mass of ice;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;

Making mass the subject of formula, we have;
Mass = 27.6 grams
Therefore, the mass of ice is 27.6 grams.
I'm thinking the answer would be D.
I hope this helps ☺ Let me know if you have any others
