You are presented with several wires made ofthe same conducting material. The radius and drift speed are givenfor each wire in terms of some unknown units \rm r and \rm v. Rank thewires in order of decreasing electron current.
Rank from most to least electroncurrent. To rank items as equivalent, overlap them.
radius=1 radius=4 radius =2 radius= 3
drift speed =5V drift speed = .5V drift speed = 2.5V drift speed = 1 V

The ranking of current from the most to the least is

Explanation:

Case Number  1 :

Drift velocity== 5v

Radius=r= 1r

Square of radius== 1

Current==C(5v)

Case Number 2 :

Drift velocity==0.5v

Radius=r=4r

Square of radius==16

Current== C(8v)

Case number 3 :

Drift velocity==2.5

Radius=r=2r

Square of radius==4

Current== C(10v)

Case number 4:

Drift velocity==1v

Radius=r=3r

Square of radius==9

Current==C(9v)

Hence, The ranking of current from the most to the least is

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
