Avector a with an x-component of 6.00 and a y-component of -4.40 is added to a vector b with x-component 3.30 and a y-component of -5.60. what is the magnitude of the resultant vector? use proper significant figures.

The magnitude of the resultant vector is 13.656 units.

Explanation:

The vector A can be represented vectorially as

Similarly vector B can be represented vectorially as

Thus upon adding the 2 vectors we get

Now the magnitude of the vector is given by:

|r|=

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.​
