Answer 1

Increase the fluid viscosity

Increase the area exposed to air.

Increase the speed of the object

Answer 2

HEYA,

Here is your answer

METHODS THROUGH WHICH WE CAN INCREASE FRICTION ARE--

1)-Increase the roughness of the contact materials.

2)-Remove lubrication between the two surfaces.

3)-By stoping relative motion.

4)-Remove wheels or bearings to create sliding friction.

5)-Increase the fluid viscosity.
