If you were doing on inquiry on the historical causes of poverty in a particular region, which would be the best categories to collect information from as you plan your paper? a) none of these categories would you gather pertinent information on the topic. b) descriptions of poverty in the area, major historical events that shaped the region, and current conditions in the region c) the geography and weather of the region, the languages spoken by people in the region, and the products produced in the area. d) political history of the area, the latest wars that took place in the area, and current stories of successful people from the region

Since we are talking about the historical causes of poverty in a determined region, the best way to start studying it would be to go to the historical sources of the region, starting by the most important historical events that shaped the region's current society. The right answer is letter B.

i think the answer is b

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
