Answer:
Based on the properties electrically charged particles, we have that unlike charges attract and like charges repel each other. In order for proper application of an electrostatically negatively charged paint to be properly applied on the metal body surface of a vehicle, require that for attraction, the surface of the vehicle should be grounded and positively charged so as to effectively attract the negatively charged paint particles as it exits the nozzle, to form a strong attachment with the positively charged surface of the vehicle
Explanation:
<u>Answer:</u>
This figure shows the Second Kepler’s Law of Planetary Motion, <em>The line that joins the planet with the Sun sweeps equal areas in equal times</em>.
According to this statement, the only way in which this is fulfilled is that the planet moves faster when it is <u>near the sun (perihelion)</u> and moves slower when it is <u>far from the Sun (aphelion</u>).
In the image shown, if points W and X are at the same distance to the Sun, this means the instantaneous velocity of the planet in both points is the same.

Answer:
4.04m
Explanation:
First you calculate the velocity of the block when it leaves the spring. You calculate this velocity by taking into account that the potential energy of the spring equals the kinetic energy of the block, that is:
To find the distance in which the block stops you use the following expression (net work done by the friction force is equal to the difference in the kinetic energy of the block):
![W_{T}=\Delta K\\\\F_f d=\frac{1}{2}m[v^2-v_o^2]\\\\d=\frac{mv^2}{2F_f}](https://tex.z-dn.net/?f=W_%7BT%7D%3D%5CDelta%20K%5C%5C%5C%5CF_f%20d%3D%5Cfrac%7B1%7D%7B2%7Dm%5Bv%5E2-v_o%5E2%5D%5C%5C%5C%5Cd%3D%5Cfrac%7Bmv%5E2%7D%7B2F_f%7D)
where Ff is the friction force. By replacing the values of the parameters you obtain:
hence, the distance to the original position is 3.96m+0.08m=4.04m
