Vector v is plotted below. What is the length of the x-component
of v?

The length of the x-component of v is 2

Explanation:

Vectors in Two Dimensions

A vector in the plane can be represented as its two components in the rectangular coordinates (x,y), assuming its initial point is the origin (0,0).

The vector plotted in the image provided has the components (-2,5).

The x-component is -2 and the y-component is 5.

The length of the component is the magnitude or absolute value of the x-coordinate, thus the length of the x-component of v is 2

answer: what are you talking about?

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.
