The force between the two point charge when they are separated by 18 cm is 3 N
<h3>How do I determine the force when they are 18 cm apart?</h3>
Coulomb's law states as follow:
F = Kq₁q₂ / r²
Cross multiply
Fr² = Kq₁q₂
Kq₁q₂ => constant
F₁r₁² = F₂r₂²
Where
- F₁ and F₂ are the initial and new force
- r₁ and r₂ are the initial and new distance apart
With the above formula, we can obtain the force between the two point charge when they are 18 cm apart. Details below:
- Initial distance apart (r₁) = 6 cm
- Initial force of attraction (F₁) = 27 N
- New distance apart (r₂) = 18 cm
- New force of attraction (F₂) =?
F₁r₁² = F₂r₂²
27 × 6² = F₂ × 18²
972 = F₂ × 324
Divide both side by 324
F₂ = 927 / 324
F₂ = 3 N
Thus, the force when they are 18 cm apart is 3 N

It takes the moon 27 days and 8 hours
A=F/M force over mass it’s 5kg that’s the mass and 200 N as the force so 200/5 that’s 40 meters per second
<span>This is due to the low cost, in energy, of enrichment per unit <span> of uranium. It's cheaper to use centrifugal isotope separation than the use of mass spectrometry. However, mass spectrometry produces highly enriched uranium compared to centrifugal. Additionally, mass spectrometry requires a less mass of natural uranium (NU) to produce the desired enriched uranium. </span></span>
Answer:
Both of them are Θ(nlgn).
Explanation:
If the array is sorted in increasing order, the algorithm will need to convert it to a heep that will take O(n). Afterwards, however, there are n−1 calls to MAX-HEAPIFY and each one will perform the full lgk operations. Since:
∑i=1n−1lgk=lg((n−1)!)=Θ(nlgn)
Same goes for decreasing order. BUILD-MAX-HEAP will be faster (by a constant factor), but the computation time will be dominated by the loop in HEAPSORT, which is Θ(nlgn).
