at the same diameter, an air bubble rises faster in liquid faster than a sand pebble falls in liquid water. The densities of air water and sand are 1.2,1000,2500 kg/M3 respectively.

Answer True of False whether or not the air buble travels faster. Need help don't understand the theory behind this question

2. A small air bubble is rising in a liquid under creeping flow. Write the biharmonic equation and boundary conditions (it is the boundary conditions that differ greatly for the case of solid sphere). If ψ = r.f(θ), obtain a fully solution and show that the drag on the sphere is 4πµRU where U is the terminal velocity and R is the bubble radius. Calculate its Brownian diffusivity.

If the government persistently runs a budget deficit, government debt will rise. If this debt rises faster than GDP, then it will account for a growing proportion of GDP.

If the government persistently runs a budget deficit, government debt will rise. If this debt rises faster than GDP, then it will account for a growing proportion of GDP. There is then likely to be an increasing problem of ‘servicing’ this debt, i.e. paying the interest on it. What effects will government investment expenditure have on general government deficits in the short run and in the long run

Dimethyl ether Ch3-o-CH3 and ethanol ch3ch2oh have the same molecular formula. Dimethyl ether evaporates faster than ethanol, which is at same temperature. Explain these observations??

For a system corresponding mainly to a uniform electric field, the flashover voltage is slightly lower than the breakdown voltage of air alone, for the same electrode gaps.

For a system corresponding mainly to a uniform electric field, the flashover voltage is slightly lower than the breakdown voltage of air alone, for the same electrode gaps. The decrease in the flashover voltage is due to the presence of small air pockets between the electrodes and solid dielectric, the influence of moisture and the non-uniformity of the electric field resulting of the difference between the permittivity of both the solid and that of air. The non-uniformity of electric field...
