Some time later at kmet, the surface wind (horizontal) pattern is observed to follow this relationship, where a is positive. u= -ax v=-ay a) sketch the horizontal flow at the surface. b) calculate the divergence of the horizontal flow. is this flow convergent, divergent, or neither? c) assuming the surface near kmet is smooth and flat, derive a formula for vertical velocity w as a function of height 2. hint: use the continuity equation for an incompressible fluid of constant density.

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j ?

Which branches of natural science include the study of an organism that lived 10 million years ago

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
