Ls -2 a solution of 4x +3= -5?.<br>

torisob [31]

Answer:

yes

Explanation:

Let's solve your equation step-by-step.

4x+3=−5

Step 1: Subtract 3 from both sides.

4x+3−3=−5−3

4x=−8

Step 2: Divide both sides by 4.

4x / 4 = −8 / 4

x=−2

The sum of all the forces acting on an <br> object is zero.

marysya [2.9K]

Answer:

Newton's first law states that when the vector sum of all forces acting on an object (the net force) is zero, the object is in equilibrium. If the object is initially at rest, it remains at rest. If it is initially in motion, it continues to move with constant velocity.

The diameter of 0-gauge copper wire is 8.252 mm. Find the resistance of a 1.00-km length of such wire used for power transmissio

Dafna1 [17]

Answer:

The value is $R = 0.321 \ \Omega$

Explanation:

From the question we are told that

The diameter is $d = 8.252 \ mm = 0.008252 \ m$

The length of the wire is $l = 1.0 \ km = 1000 \ m$

Generally the cross sectional area of the copper wire is mathematically represented as

$A = \pi * \frac{d^2}{4}$

=> $A = 3.142 * \frac{ 0.008252^2}{4}$

=> $A = 5.349 *10^{ - 5} \ m^2$

Generally the resistance is mathematically represented as

$R = \frac{\rho * l }{A }$

Here $\rho$ is the resistivity of copper with the value $\rho = 1.72*10^{-8} \ \Omega \cdot m$

=> $R = \frac{1.72 *10^{-8} * 1000 }{5.349 *10^{ - 5} }$

=> $R = 0.321 \ \Omega$
