Look at this sine wave.
 
 
This is one cycle. It starts at 0 then goes positive then crosses 0 and goes negative then ends at 0. The end of one cycle is also the beginning of the next cycle so we can see it becomes 0 two times in one cycle. A 50Hz sine wave will have 50 cycles in one second. 2 x 50 = 100 so the answer is a 50Hz sine wave will be zero volts 100 times in 1 second.
