Select the statement below that is true about wind. The greater the different in air pressure, the stronger the winds.
None of the above.
When there is little difference in air pressure, the stonger the winds.
Air moves from a place of low pressure to a high pressure.
Thank u for helping

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
