Dr. strayer is conducting longitudinal research on factors that correlate with getting older. she is most likely to find that: intelligence declines sharply with age. no matter how much older people practice their mental skills, they still do very poorly on intellectual tasks. there is severe memory impairment as people reach late adulthood. most people experience slight declines in their intellectual abilities as they age.

we can solve this via the kinematic equation:

where the vertical velocity is zero and so:

since the height of the building is 29.3 meters then:

the ball was in motion for approximately 2.45 seconds

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
