c. rail
d. shipping

Soon after the Soviet system collapsed, the Russian economy was hit by depressions.

More people, products, and items use rail transportation than any other type of transportation in Russia.

Explanation:

The economic depression created by the Soviet system collapsed was twice as great as in the Western media of the infamous Great Depression of 1930. The collapse has had catastrophic economic and social consequences overall for its population since during the first four years the GDP decline in this region is 45%.

Rail transport in Russia is one of the largest in the world. There are seventeen regional railways in Russia. Due to poor road roads, rail is a very common mode of transport.  During the Soviet Union rail transport was the largest type of transport in Russia. In that time the railways were modernized and had a world-class status.

explanation:

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.
