The drag on the hull of a ship depends in part on the height of the water waves produced by the hull. the potential energy associated with these waves therefore depends on the acceleration of gravity g. hence, we can state that the wave drag on the hull is d= f(rho[infinity],v[infinity], c, g) where c is a length scale associated with the hull, say, the maximum width of the hull. derive the non-dimensional groups for this problem, one of which is non-dimensional drag. hint: choose rho[infinity],v[infinity], c as the basis variables.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

he . if i may ask what i your question exactly?

explanation:

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
