1 byte = 8 bits
1 nybble = 4bits
1 word = 32bits
1 halfword =16bits
1 doubleword = 64bits
16k words = 512 bits(ie 512/8 = 64bits)

Bits can represent only two number 0 & 1. so,

A 1-bit address can address two words (0, 1). [ 2^1 = 2 ]

A 2-bit address can address four words (00, 01, 10, 11). [ 2^2 = 4 ]

A 3-bit address can address eight words (000, 001, 010, 011, 100, 101, 110, 111). [ 2^3 = 8 ]

now 16K words in total = 16000 words => each single word can thus be addressed in 14 bits [ AS 2^13 = 8192 & 2 ^ 14 = 16384 ] => so 14 bits are needed to address each word in memory.
