the maximum height reached by the barnacle is m. done
Answer
Answer:
2
Explanation:
Step1: Identify circle radius
The radius of the circle is 1 m.
Step2: Calculate maximum height
The maximum height occurs when the barnacle is at the top - most point of the circle. The water level is at (y = 0). The center of the circle is at the water - level. The maximum height (h) is the sum of the radius of the circle and the height of the center of the circle above the reference (water - level). Since the radius (r=1) m and the center of the circle is at the water - level ((y = 0)), the maximum height (h=r + r=2) m.
