Ineed when pulled, stretchy objects such as rubber bands exert elastic force. gently hold one end of the rubber band and pull on the other end. you will feel the rubber band pulling back. how does the force exerted by the rubber band change as you increase its length? what do you observe?

The rubber band exerts more elastic force the more it is increased in length. I also observed that it became more difficult to increase the length of the band as the band's energy worked against my energy.

yeah what they said

Explanation:

the california missions began in the late 18th century as an effort to convert native americans to catholicism and expand european territory. there were 21 missions in all, lasting from 1769 until about 1833.   the missions were built by the spanish starting in 1769 in order to “colonize” the territory of alta california. so the missions were important because they were the means of settling california. it also wanted to keep other european countries out of alta california. building settlements along the coast would them meet these goals. missionaries wanted to convert the indians to the roman catholic faith. california indians did much of the work to build missions.
