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.

The ph is the a. independent variable b. the dependent variable c. control group

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?

The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656(red) and 486 (blue). light from a hydrogen lamp illuminates a diffraction grating with 500 lines per mm, and the light is observed on a screen 1.50 behind the grating. what is the distance between the first-order red and blue fringes?
