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.

a chuck wagon with an initial velocity of 4 m/s and a mass of 35 kg gets a push with 350 joules of force. what is the wagon's fi

Kitty [74]

Answer:

the final velocity of the wagon is 6 m/s.

Explanation:

Given;

initial velocity of the wagon, u = 4 m/s

mass of the wagon, m = 35 kg

energy applied to the wagon, E = 350 J

The final velocity of the wagon is calculated as;

E = ¹/₂m(v² - u²)

$m(v^2-u^2) = 2E\\\\v^2-u^2 = \frac{2E}{m} \\\\v^2 = \frac{2E}{m} + u^2\\\\v = \sqrt{\frac{2E}{m} + u^2} \\\\v = \sqrt{\frac{2(350)}{35} + (4)^2}\\\\v = 6 \ m/s$
