Physics is defined as:

• The study of plants, animals, and nature

• Develped out of efforts of man trying to explain our physical environment.

• Developed out of efforts of man trying to understand space and astronomy

• Is the science of the human body

Given  $2m+n=r$  , solve for  $m$  .

•  $m=\frac{r-n}{2}$  

•  $m=r-n-2$  

•  $m=\frac{r}{2}-n$  

Given  $a-b=c$  , solve for  $b$  .

•  $b=c-a$  

•  $b=a-c$  

•  $b=a+c$  

Given  $n=2rt$  , solve for  $r$  .

•  $r=n-2t$  

•  $r=\frac{n}{2t}$  

•  $r=\frac{2n}{t}$  

Given  $pq=rsT$  , solve for  $q$  .

•  $q=\frac{rsT}{p}$  

•  $q=rsT-p$  

•  $q=\frac{p}{rsT}$  

Given  $a=b+c^2d$   , solve for $c$  .

•   $c=\pm\sqrt{a-b-d}$ 

•   $c=\pm\sqrt{\frac{b-a}{d}}$ 

•   $c=\pm\sqrt{\frac{a-b}{d}}$ 

Given  $a^2b=2c-d$   , solve for $a$  .

•  $a=\pm\sqrt{2c-d-b}$  

•  $a=\pm\sqrt{\frac{2c-d}{b}}$  

•   $a=\pm\sqrt{2bc-bd}$
