The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation R=pL/(pi)d^2 where p represents the resi

stivity of the wire’s material, L represents the length of the wire, and d represents the diameter of the wire.
What happens to the resistance of the wire as the diameter approaches 0?
The resistance approaches 0.
The resistance approaches pi.
The resistance approaches L.
The resistance approaches infinity.

Answer:

Option 4th is correct.

The resistance approaches infinity.

Step-by-step explanation:

The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation:

R = \frac{p L}{\pi d^2}        ....[1]

where,

p is the  the resistivity of the wire’s material

L is the length of the wire.

d represents the diameter of the wire.

We have to find resistance of the wire as the diameter approaches 0.

As diameter approaches to 0.

⇒d \rightarrow 0

Substitute in [1] we have;

R = \frac{p L}{\pi 0^2}

⇒R \rightarrow \infty

therefore. the resistance approaches infinity as the diameter approaches 0.

I think
A. convert the time to seconds, so all the time are 7070sec and the total course to meter.
so 31300meter
Vector = TotalCourse÷total time
V=31300/7070=4.427157m/s
convert it to km/h so 4.427157×36÷10=
15.9377km/h
B. 45÷15.9377=2.823Hour
it means that around 2 Hour 48Minutes more.
i think the teacher need to simplify it

slamgirl [31]

alison, beatrice and chole each of them have at first 56, 8, 32 books.

alison, beatrice and chole each had some books. alison gave beatrice and chole some books that doubled the number of books they had, lastly chole gave alison and beatrice some books that doubled the number of books they had. each of them had 32 books at the end.

<h3>What is Working backward?</h3>

Working backward is process in which calculation done in reverse direction.

let alison, beatrice and chole has x,y and z books initially,

alison gave beatrice and chole some books that doubled the number of books they had
alison, beatrice and chole has (96-2y-2z), (2y) , (2z)
chole gave alison and beatrice some books that doubled the number of books they had. each of them had 32 books at the end.

alison, beatrice and chole has 2(96-2y-2z), 2(2y) , (96-2(96-2y-2z)-4y)

at the end,
beatrice = 32

4y=32

y = 8

chole =32

96-2(96-2y-2z)-4y)=32
z=32

alison = 96-y-z

x=96-8-32
x=56

Thus the required alison, beatrice and chole each of them have at first 56, 8, 32 books.
