Your Answer for Question 1:
Principle of spatial locality (locality in space) -
It is more likely that you go to a local movie theater or shop at a local mall because it is closer to your home than somewhere far away. 

Principle of temporal locality (locality in time) - 
It is more likely that you remember thee material you learned in CS61c better a month after taking the course rather than a year. 


Your Answer for Question 2:
The cache index is essentially determined by (block address) % (# of cache blocks in the cache). Because the number of entries in the cache is a power of two, modulo can be computed by using only the low-order log2 (cache size of blocks) bits of the address. This makes for easy direct mapping between memory address and location in cache and easier computing since computers use binary.
