Answer:

D.) Dissolving solid NaF in water

Explanation:

Dissolving solid NaF in water will produce an electrical-conducting solution.

Dissolving sugar in water will not since sugar just dissolves but not into ions. Oil is nonpolar so water nor NaBr will dissolve in it

Replacing electrical cables. Wouldn't it be a matter of knowing what is a suitable conductor in this situation. The solution produced in the situation would be to use a copper wire.

Two parallel wires are separated by 6.10 cm, each carrying 2.85 A of current in the same direction. (a) What is the magnitude of
Westkost [7]

Answer:

The force per unit length is 2.66 \times 10^{-5} \ N/m

Explanation:

The current carrying by each wires = 2.85 A

The current in both wires flows in same direction.

The gap between the wires = 6.10 cm

Now we will use the below expression for the force per unit length. Moreover, before using the below formula we have to change the unit centimetre into meter. So, we just divide the centimetre with 100.

F/l = \frac{\mu _0i_1 i_2}{2\pi d} \\i_1 = 2.85 \\i_ 2 = 2.85  \\\mu _0 = 4\pi \times 10^{-7} \\d = 0.061 \\F/l = \frac{4\pi \times 10^{-7} \times 2.85 \times 2.85}{2 \pi \times 0.061} \\= 2.66 \times 10^{-5} \ N/m

How do mass and speed affect kinetic energy?
Lunna [17]
The mass affects the kinetic energy because the more the mass the more energy is given to the object and the speed<span> affects by making it go faster and longer, so whenever speed goes up so does energy.</span>

How much time does it take a person to walk 12km north at the velocity at a velocity of 6.5 km/hrs?
alukav5142 [94]

"6.5 km/hr" is not a velocity.  It's just a speed, so
we don't know what direction he's walking.

If he happens to be walking north, then it takes him

               (12 km) / (6.5 km/hr)  =  1.846... hours  (rounded) .

If he's walking in any other direction, it takes him longer than that.

If the angle between north and the direction he's walking is
90 degrees or more, then he can never cover any northward
distance, no matter how long he walks.
