A 16.0 Ω, 13.0 Ω, and 7.00 Ω resistor are connected in parallel to an emf source. A current of 6.00 A is in the 13.0 Ω resistor.

Calculate the equivalent resistance of the circuit. Answer in units of Ω.

The current in one parallel resistor doesn't tell us the equivalent resistance of the circuit. And the equivalent resistance of the circuit doesn't depend on the current through any of the resistors, or the voltage applied to them, or even whether there IS any current through any of them.  

Resistors in parallel have the same equivalent resistance even if they're wrapped in tissue, placed in a matchbox, and stored in the back of a drawer in a desk and locked in a dusty warehouse.

The equivalent resistance of 16Ω, 13Ω, and 7Ω all in parallel is the reciprocal of

(1/16) + (1/13) + (1/7) .

That's  1 / (0.0625 + 0.0769 + 0.1429)

That's  1 / (0.2823)

That's   <em>3.543 Ω</em> .

Answer:3.54ohms

Explanation: connection in parallel

1/Rt= 1/R1+1/R2+1/R3

1/Rt= 1/16+1/13+1/7

1/Rt= 91+112+208/1456

1/Rt= 411/1456

411Rt= 1456

Rt= 1456/411

Rt= 3.54ohms

The force required to stretch a Hooke’s-law
Setler [38]

I think this is correct, but I am not entirely certain.

Find the force constant of the spring:

F = - KX

(0 - 62.4) = -K(0.172m)

-362.791 = -K

362.791 N/m = K


Find the work done in stretching the spring:

W = (1/2)KX

W = (1/2)(362.791)(0.172m)

W = 31.2 J

Abdou was explaining to a classmate that graphite is a good lubricant
balu736 [363]

The fact that the layers of graphite are held together by only weak Van der Walls forces implies that they can slide over each other.

<h3>Why is graphite a solid lubricant?</h3>

We know that graphite is composed of layers. These hexagonal layers are held together by weak Van Der Walls forces and as such are able to slide over each other. The carbon atom in each layer are held together by strong covalent bonds.

The fact that the layers of graphite are held together by only weak Van der Walls forces implies that they can slide over each other and as such make the graphite fluid.

Thus, the image that shows these layers of graphite is attached to this an answer
