Water is flowing in a straight horizontal pipe of variable cross section. where the cross-sectional area of the pipe is 3.70·10-2 m2, the pressure is 6.10·105 pa and the velocity is 0.260 m/s. in a constricted region where the area is 9.50·10-4 m2, what is the velocity?

v = 10.1 m/s

Explanation:

As we know that by the law of conservation of volume the rate of volume flowing through the pipe will remain conserved

so here we have flow rate given as

now we have

now we have

now from above equation we have

i would think klcio3

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
