The right answer is CaF2
Calcium fluoride is an inorganic compound of formula CaF2. This ionic compound consisting of calcium and fluorine is naturally present in nature in the form of fluorine (also known as fluorite). It is the world's leading source of fluoride.
It is a solid insoluble in water, whose structure is cubic where each atom of calcium is adjacent to eight atoms of fluorine, and each atom of fluorine to four atoms of calcium.
It would be generation 5 in which there will be almost 100% non-singing females if there are no changes in the birds’ environment and interactions
I believe the answer would be 16:1
This can be looked at by assuming the motor speed is say 2000 RPM. Through the first reduction it is reduced 4 times to 500 RPM. The second reduction of 4:1 reduces it down to 125 RPM. The total reduction is the motor speed of 2000 RPM divided by the final speed of 125 or 16. A gear ratio is the ratio used to determine the angular speed and torque of a geared system.
