which of the following is an example of a vector quantity?
i picked A
identify as vecor or scalar
1. speed of a snail---vector
2. the time it takes to run a mile-scal
3. the free-fall accleration---vector
3. multiplying or dividing vecors by scalars results in
c. vectors if multiplied scalar if divided
d. scalar if multiplied vector if divided
im not really sure on this one...

speed, of a snail or otherwise, is a scalar. Add direction, and it is a vector.
Multiply, or to divide vectors is a little complicated.
ordinary multiplication or division results in a vector.
dot product results in a scalar
cross product results in a vector which is perpendicular to both of the original vectors.
ordinarily, plain multiplication and division is reserved for time dependent phasors, and for spacial vectors, multiplication is usually either dot or cross. However, this is not always the case, and one can do any math operation with vectors. This may be a little more advanced than you are ready for.
