During the medieval period, which group played an important role in staging plays in various parts of towns? a. landholders b. shop owners c. peasants d. trade guilds

D. trade guilds

Explanation:

Trade guilds were associations of craftsmen or merchants that were particularly important in the period between the 11th and the 16th centuries. These associations were formed as an attempt to protect the professional interests of these groups. However, this was not the only social or economic role that the trade guilds played. The guilds were involved in many social and economic activities, including the staging of plays.

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.
