An object is moving in three dimensions, following a circular path at a constant radius from the origin, with a constant angular velocity ω--зі + k. if its linear velocity is expressed as v-vi + vyj+ vzk, what is the value of vy at the moment when its position vector is r-i+ 2j - 3k?

Explanation:

As we know that due to rotational motion the linear velocity of any point is given as

here we know that

now we have

So y component of velocity is given as

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.​
