Basically, longer (and/or more complex) passwords are harder to brute
force. It takes:
36^5/2 = 30,233,088 guesses on average to find a 5 character password
consisting of random letters and numbers (typical passwords are less
random so using a dictionary can decrease this).
36^10/2 = 1,828,079,220,031,488 guesses on average to find a 10
character password. In other words about 60 million times longer.
