F = m * a
F = 15 kg * 8 m/s²
F = 120 N
Answer B

<span>If a plane has a velocity of 300 km/h and a tailwind of 20 km/h, then the vectors of both forces would add (assuming that the tailwind is blowing exactly at the airplanes back) to a total of 320 km/h. Hope it helps

Answer: The answer is 19,600 newtons.
Explanation:
Answer:
Explanation:
We know that the electric force equation is:
- k is the electric constant
- r is the distance between the particles
- q1 and q2 are the particle
Now, we have three particles, the first one at x=0, the second one at x=2a and the third in some place between these two particle.
1. Let's find the electric force between the first particle and the third particle.
r(31) is the distance between 3 and 1
2. Now, let's find the electric force between the third particle and the second particle.
r(32) is the distance between 3 and 2.
Now, or
The net force must be zero so:
We just need to solve it for r(31)
Therefore the distance from the origin will be:
I hope it helps you!
