B) in Physics, charge conservation is the principle that the total electric charge in an isolated system never changes. The net quantity of electrical charge, the amount of positive charge minus the amount of negative charge in the universe is always conserved.

0.318 cm. What is the ideal mechanical advantage?
vodomira [7]

The ideal mechanical advantage will be 8.017. The ideal mechanical advantage value may be grater than the actual value of mechanical advantage.

<h3>What is mechanical advantage ?</h3>

Mechanical advantage is a measure of the ratio of output force to input force in a system, it is used to obtained efficiency of  forces in levers and pulley.

The ideal mechanical advantage is found as;

\rm IMA = \frac{d \pi}{l} \\\\ \rm IMA = \frac{0.812 \times  \pi}{0.318} \\\\ IMA=8.017

The ideal mechanical advantage will be 8.017.

To learn more about the mechanical advantage, refer to the link;

Kiley went 5.7 km/h north and then went 5.8 km/h west. From start to finish, she went 8.1 km/h northwest.
avanturin [10]
5.7 km/h north and 5.8 km/h west are instantaneous velocities, while 8.1 km/h northwest is the average velocity.<span>

The answer choice above is correct.

The instantaneous velocities are the actual </span>velocities while traveling ( the velocity during that instant ). The average velocity is the average of the instantaneous velocities ( the speed in one direction equivalent to the two speeds <span>in different directions ).

I used speed in the explanation because velocity is speed with direction.</span>
