Question

During lecture 1 @26:16, why is the constant multiplied by square root of h/g proportional to sqrt(h) ?

Answer 1

t is proportional to √h because neither C nor g depend on h.

Answer 2

Oh, as in C and g are constant values? is that what it means to be independent of h?

Answer 3

Not necessarily. These could change with respect to some other quantity. As long as they do not change with h, then you can say that dependence of t with respect to h is a square-root one.

Answer 4

Many thanks! That makes sense now.
