Rearrange the equation for velocity to solve for time, t. V=D/V The answer is T=D/V. I have to show my work. Is it really as simple as swapping the t and v just like that, or is it something more complicated? ----------------------------------------------...

carry out the operation (1.62 * 10^3) + (3.4 * 10^2) If the answer is 1.96 10^3 HOw do I get there? what do I do? Help plz

Are elements with the same number of valence shell electrons located in the same family or period? What is a FAMILY? PERIOD?

OOps the original for the first question was V=D/T not V=D/V
