The current supplied to an air conditioner unit is 2.54 amps. the air conditioner is wired using a 10-gauge (diameter 2.588 mm) wire. the charge density is n = 8.48 ✕ 1028 electrons/m3.find the following magnitudes.(a) current density (in a/)the drift velocity (in m/s)?

482853.39714 A/m²

Explanation:

I = Current = 2.54 A

d = Diameter = 2.588 mm

r = Radius =

A = Area =

n = Charge density =

q = Charge of electron =

Current density

The current density is

Drift velocity

The drift velocity magnitude is

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
