2) [10 marks How does the speed of deep water waves depend upon their wavelength (you may neglect surface tension and the depth of the water)? How does the period of oscillation of a drop of water depend upon its radius (you may neglect gravity and any interaction of the drop with its surroundings)? Estimate the length-scale at which the transition from gravity to surface tension being the dominant process to consider occurs. [The surface tension of water is approximately...

Based on experimental work, the surface tension (s) of water can be described as a function of temperature (T) using the following relationship: where the range of temperature is: 0 °C < T < 100 °C. Plot the shape of the meniscus as a function of temperature for θ = 55 deg. Assume g is independent of temperature and R=2.5E-3 mm.

SURFACE TENSION. You can make a needle float, even though the needle is heavier than water. Obtain a large, flat pan of water. Carefully, on the water’s surface, lay out a SINGLE-PLY (thickness) of double-ply toilet paper. Gently ease a needle onto the paper, keeping the needle level. Using a fork, slowly press down on the toilet paper to sink the paper out from under the needle. (Do not touch the fork to the needle.) It may take a few...

Capillary waves are waves that run across the surface of water because of the surface tension of the water. (You can see these waves if you gently touch your finger to the water surface in a glass of water.) If the surface tension of water is 0.07 Newtons/m, if the density of water is 1000 kg/m, and if the waves have a wavelength of 3 mm (waves this short aren't affected by gravity so ignore g), estimate the speed of...

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...

To calculate the electric flux through a surface of arbitrary shape you need to: a. multiply the total area of the surface by the average magnitude of the electric field at the surface. b. split the surface into small areas, and then add up the product of the perpendicular component of the electric field through each small area times the small area. c. split the surface into small areas, and then add up the product of the electric field times...

please explain briefly, step by step.
z() Consider a bucket of water spinning with constant angular speed w. We interested in finding the shape of the water's surface, z(r). We do this by first noting that in the rotating frame of the bucket, a small water elem mass m on the surface of the water is in static equilibrium. The figure shows the three forces acting on the water element: Centrifugal force Fc, gravity Fg and the normal force n...
