Two point sources are simultaneously creating waves with a wavelength of 6 cm. Point X lies between the two sources. It is 9 cm from one source and 15 cm from the other. What wave heights do you expect at point X? A. The waves will never get very high or low. B. The waves may get very high, but will never get very low. C. The waves may get very low, but will never get very high. D. The waves will sometimes get very high and very low.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

the answer is 12 as i may remember
