Please compute the answer of the given problem

Problem 1- Consider an object falling through air. How is the terminal velocity impacted when certain physical properties are changed, let us define the following:

A- p(o): density of the object

B- p(air): density of the air

C- m: mass of the block

D- A: effective cross-sectional area of the block

E- vT: terminal velocity of the block

F- d: drag coefficient of the block

Problem 2- For each of the properties below, state whether terminal velocity will increase, stay the same, or decrease.

A- p(air) doubles

B- m doubles

C- d doubles

D- p(air) and A double

E- m and A double

F- A doubles

G- p(0) doubles

I need help to solve the above problems.
