Answer:
D. If the distance between the crests of the waves increase, the frequency decreases.
Explanation:
Wavelength is the distance between two successive crests and troughs while frequency is the number of complete cycle per seconds
Velocity = Frequency × wavelength
Frequency and wavelength are inversely proportion
Explanation:
Moles=mass/molar mass
moles × molar mass = mass
0.206 x 119= mass
Mass= 24. 51grams
The filtration process is generally used to separate a suspension mixture where small solid particles are suspended in liquid or air. ... The water that has been run through the filter is called the filtrate. The particles that are removed from the water by the filter are called the residue
Answer:
A. When water moves into a crack and freezes, it expands and forces the crack wider.
Explanation:
A crack in a rock can fill with water which then freezes as the temperature drops. As the ice expands, it pushes the crack apart, making the crack larger. When the temperature rises again, the ice melts, and the water fills the newer parts of the crack. Once the water freezes again when the temperature drops, the expansion of the ice causes further expansion to the crack.
