Answer:
The compound is dissolved in water
Explanation:
"aq." is the abbreviation for "aqueous" ( watery).
In chemical equations the symbol (aq) means that the substance is dissolved in water.
The formula for finding the kinetic energy of an object is:
KE = 0.5MV^2,
Where:
M= Mass
V = Speed
From the information given above,
M = 21 kg
V = 3 m/s
KE = 0.5 * 21 * 9 = 94.5
Therefore, the canoe's kinetic energy is 94.5 J
Cells of various types have different functions because cell structure and function are closely related. It is apparent that a cell that is very thin is not well suited for a protective function.
I think the answer is B sorry if I’m wrong
