Read the sentence. during the cold war, scientists competed in the "space race." which revision changes the sentence to draw attention to the object of the action rather than the people or things performing the action? the "space race" by competing scientists occurred during the cold war. during the cold war, scientists led the "space race" competition. during the cold war "space race," scientists competed. the "space race" was a cold war competition by scientists.

no it who u choose to be. let no one tel u what or who to be;

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.
