Answer:
effective ground-fault current path
Explanation:
Answer:
if the old force is F, the new force is F/9
Explanation:
Recall that the Coulomb force between to charges is inversely proportional to the square of the distance between the charges.
Therefore, if the original distance "d" changes now to be "3d" (tripled), the denominator of the force expression will change from:
thus reducing the original force by a factor 1/9
So if the old force is F, the new force is F/9
Answer:
5 neutrons
Explanation:
Both protons and neutrons have a mass of about 1 atomic mass unit (amu). The number in the notation for an isotope is its mass in amu. That means the number is essentially the sum of protons and neutrons in the isotope (electrons don't contribute significantly to the mass).
If lithium has 3 protons, lithium-8 has 8 - 3 = 5 neutrons.
Answer:
Comets
Explanation:
Comets are planetary celestial bodies consisting of ice and dust, sometimes rocky particles formed in the region of the solar system. Long-period comets propagate towards the Sun by gravitational perturbations caused by passing stars. Some comets usually hyberbolic comets, move through the inner Solar System prior to entering the interstellar region. Short period comet lies beyond the orbit of the Neptune.
The Jovian planets include Jupiter, Saturn, Uranus, and Neptune.
Therefore, leftovers of comets (planetesimal bodies) formed in the region of the solar system that are now occupied by the Jovian planets is due to the dusty particles associated with the comets.
Answer:
C
Explanation:
Generally, the speed of light slows down when passing through a medium that is not a vacuum. This is not always the case, but I will be ignoring the rare/exotic exceptions. Light has a harder time traveling through solids and liquids than it does with gases.
