What size is a standard margin? a. 1.5 inches c. 5 inches b. 2 inches d. 1 inch

The anwser is D: 1 Inch

   D. 1 inch

Explanation:

  Standard margins of a Microsoft document are 1 inch of the left and right sides of the page and also from the top and bottom. As they´re standard every time you open a new document the margins are automatically set to these dimensions.

  I hope this answer helps you.

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.

u don't know that wow good luck tho bud
