The magnetic flux that passes through one turn of a 12-turn coil of wire changes to 5.50 from 9.11 wb in a time of 0.0309 s. the average induced current in the coil is 272 a. what is the resistance of the wire?

The resistance of the wire is 5.15 ohm

Explanation:

Given Magnet flux change through one turn is

Time take

Induced current

Number of turns ,N= 12 turns

Therefore total change in flux through 12 turns is

Now induced voltage in the coil is given by

where R = Resistance of the wire

=>

Thus the resistance of the wire is 5.15 ohm

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

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
