There are two different maps of ohio. the scale on the first map is 1 cm to 10 km. the distance from cleveland to clncinnati is 40 cm. the scale on the second map is 1 to 50 km what is the distance from cleveland to cincinnati on the second map explain your reasoning

First map

1 cm 10 km

40 cm x

x= (40 * 10) /1

x= 400 km, Cincinnati is 400 km away from Cleveland.

Second map

1 cm 50 km

x 400 km

x= (400 * 1) /50

x= 8, Cincinnati is 8 cm away from Cleveland.

yeah uhm looks pretty good lol

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.
