Suppose you and a friend are test driving a new car. you drive out of the car dealership and go 10 miles east and then 8 miles south. then your friend drives 8 miles west, and 6 miles north. if you had the dealer's homing pigeon in the car. how far do you think it would have to fly to get back to the dealership? use the simulation to test ideas. the distance that the bird has to fly represents the sum of the 4 displacement vectors. use the simulation to test ideas you have about vector addition. after your tests, describe how you can use the simulation to add vectors.

a =12miles

b =10miles

ab =2miles

Explanation:

at first the car is drown out of dealership and went 10 miles east and then 8 miles south

then your friend drives 8 miles west and 6 miles north.

then the distance it flies to get back to dealership is

10²+8 ²=12miles

8²+6²=10miles

12-10= 2 miles

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.​
