1. Two wires - A and B - with circular cross-sections have identical lengths and are made of the same material. Yet, wire A has
PolarNik [594]

Answer:

Diameter of wire B is 2 times the diameter of wire A

Explanation:

We have given two wire A and B

They are made up of same material and length of both the wire is sane

So l_A=l_B

Let the resistivity of both the wire is \rho

It is given that wire A has 4 times the resistance as wire B

So R_A=4R_B

So \frac{\rho l_A}{a_A}=4\frac{\rho l_B}{a_B} ( As l_A=l_B )

\frac{a_A}{a_B}=\frac{1}{4}

\frac{d_A^2}{d_B^2}=\frac{1}{4}

\frac{d_A}{d_B}=\frac{1}{2}

d_B=2d_A

So diameter of wire B is 2 times the diameter of wire A

After fertilization in the fallopian tube, how many days will the zygote travel before arriving at uterus?.
natta225 [31]

After fertilization in the fallopian tube, It will take 6-12 days for the zygote to travel before arriving at the uterus.

<h3>What is a zygote?</h3>

A zygote is, generally speaking, a cell created by the fusion of two gametes; the growing person is created from such a cell.

It takes the zygote around 6–12 days following fertilization in the fallopian tube for the fertilized egg to travel to the uterus and attach to the uterus, a process known as implantation.

Hence It will take 6-12 days for the zygote to travel before arriving at the uterus.

To learn more about the zygote refer;
