1. table 3.1 shows a section of a tide table for a sandy shore on july 15th.

there was a full moon on july 15th.
tidal range is defined as the difference between a high and the following low tide.
use table 2.1 to calculate the tidal range at this shore on july 15.

Explanation:

Step1: Identify high and low tides

From the table, high tides are \(4.09\) m (at \(07:45\)) and \(4.34\) m (at \(20:03\)), low tides are \(0.26\) m (at \(00:53\)) and \(0.42\) m (at \(13:11\)).

Step2: Calculate tidal ranges

First tidal range: \(4.09 - 0.42=3.67\) m.
Second tidal range: \(4.34 - 0.26 = 4.08\) m.

Answer:

The tidal ranges are \(3.67\) m and \(4.08\) m.
