20 points) Water striders walk on water by taking advantage of surface tension; they live on the surfaces of ponds, vers, and even the open ocean. A team of scientists at MIT decided to build a robotic water strider to mimic the true strider's locomotion and lean more about not just how it floats, but how it moves around the surface of the water (see picture below) Both the actual water strider and its robotic counterpart are held up by...

A bug on the surface of a pond is observed to move up and down a total vertical distance of 0.13 m , lowest to highest point, as a wave passes. a) What is the amplitude of the wave? b) If the amplitude increases to 0.19 m , by what factor does the bug's maximum kinetic energy change? KE2maxKE1max KE2maxKE1max =

3. A papercip made of steel wire (psteel-7500 KE/m3) floats in water supported by surface tension (o-0.073 N/m). This paperclip has length =50 mm, cross-section diameter 1.5 mm and perimeter 103 mm. If the manufacture products the same paperclip with silver (P silver 10490 Km), will it be able to float in water with the same surface tension? Please show the calculation to support your answer.

3. Surface tension of a water strider For an animal the size of a human, surface tension seems to be a rather small and insignificant force (though it plays an important if unnoticed role in our breathing). But as animals get smaller, surface tension gets increasingly significant. (The weight of the animal goes down with the cube of the size while the surface tension only decreases linearly.) For animals like the basilisk lizard and the jacana (bird), they appear to...
