Problem $2$

Figure $1\mathrm{.}10($a$)$ from Song $(2018),$ shown at right, illustrates the capillary rise, $h,$ for a hydrophilic fluid.

Part A

If the tube had larger dimeter, would $h$ be smaller or larger, and why?

Part B

If the fluid were hydrophobic, would $h$ be positive or negative, and why?

Part C

If the entire system were in an elevator accelerating upward at $2\mathrm{.}00\frac{m}{s^2},$ would $h$ be smaller or larger, and why?
