The answer is B. A and C. Spring tides occur during a new moon and full moon
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

Answer:
S = 11488.42 m
Explanation:
Given,
The speed of the jet, v = 0.74 Mach
= 253.82 m/s
The altitude of the jet, h = 10000 m
Since the jet is travelling horizontally, the vertical component of velocity Vy = 0
The equation for a projectile projected from a height h is given by,
S = Vx [Vy + √(Vy² +2gh)] / g
Since Vy = 0
S = Vx √(Vy² +2gh) / g
= 253.82 x √(2 x 9.8 x 10000) / 9.8
= 11488.42 m
Hence, the humanitarian aid package should be delivered ahead of distance, S = 11488.42 m
Solar power is a renewable
energy resource source depends on time of
day and time of year. Its source is from the sun and the batteries that
needs this power does not run out of energy.
