Final answer:
It takes about 2.5 seconds for a piece of ice to hit the water when falling freely from a glacier without air resistance.
Step-by-step explanation:
According to the information given, it takes about 2.5 seconds for a piece of ice to hit the water. This is assuming that the ice is falling freely and there is no air resistance. When a chunk of ice breaks off a glacier and falls freely, it accelerates due to gravity until it hits the water. Based on this, we can conclude that the statement 'It took just thirty seconds from seeing the iceberg to hitting the iceberg' is False.
