Pressure: one of the dangers of tornados and hurricanes is the rapid drop in air pressure that is associated with such storms. Assume that the air pressure inside of a sealed house is 1. 02 atm when a hurricane hits. The hurricane rapidly decreases the external air pressure to 0. 910 atm. What net outward force is exerted on a square window of the house that is 2. 03 m on each side? (1. 00 atm = 1. 01 × 105 pa).

Nathan is an ecologist. he’s studying the effect of secondary consumers on primary consumers. his current research focuses on a population of blue jays and crows. they eat caterpillars and mice. if the number of blue jays increases, what are the likely effects on other populations? 1the number of crows will increase. 2the number of mice will decrease. 3the number of mice will remain the same. 4the number of caterpillars will decrease.
