Weight is a force so by F = ma, we have
weight = 10 x 1.6
= 16 N

An electric current of 200 A is passed through a stainless steel wire having a radius R of 0.001268 m. The wire is L = 0.91 m lo

denis23 [38]

Answer:

The value is $T_m = 435.2 \ K$

Explanation:

From the question we are told that

The current is $I = 200 \ A$

The radius is $R = 0.001268 \ m$

The length of the wire is $L = 0.91 \ m$ \

The resistance is $R = 0.126 \ \Omega$

The outer surface temperature is $T _o = 422.1 \ K$

The average thermal conductivity is $\sigma = 22.5 W/mK$

Generally the heat generated in the stainless steel wire is mathematically represented as

$Q = \frac{Power}{ \pi r^2L}$

$Q = \frac{I^2 R}{ \pi r^2L}$

=> $Q = \frac{200^2 * 0.126}{3.142 * (0.001268)^2 * 0.91}$

=> $Q = 1.096*10^{9}\ W/m^3$

Generally the middle temperature is mathematically represented as

$T_m = T_o + \frac{Q * r^2 }{ 6 * \sigma }$

$T_m = 422.1 + \frac{1.096*10^{-9} * 0.001268^2}{6 * 22.5}$

$T_m = 435.2 \ K$

The sum of the initial and final velocity is divided by 2 to find the average.

4vir4ik [10]

The average velocity is obtained by ( u + v)/2.

<h3>What is average velocity?</h3>

The term velocity refers to the rate of change of displacement with time. Velocity is a vector quantity thus it has both magnitude and direction. The velocity of a body could also be shown by the use of the vector notation.

To obtain the average velocity;

Let the initial velocity be u

Let the final velocity be v

It then follows that the average velocity = ( u + v)/2
