according to the question are microwaves and X-rays
Honed I don’t know where the question is
Answer:
3.825*10^-6 N
Explanation:
As particle 1 and particle 3 has opposite types of charge, particle 3 will be attracted to particle 1. And as particle 2 and 3 has the same sign, they will repel each other. Due to the position of the particles, both the Force that 1 exerts on 3 and the force that 2 exerts on 3, will have the same direction. Now, you need the magnitude. You can use the following expression:
K is the Coulomb constant equal to 9*10^9 N*m^2/C^2, q1 and q2 is the charge of the particles, and r is the distance.
Force 1 on 3 is equal to:
Force 2 on 3:
The magnitude of the resultant force is the addition of both forces:
The answer to your question is B
Answer:
I guess it is the reason
Explanation:
A dam is thicker at the bottom than at the top because the forces exerted are strongest close to the ground. Water pressure increases proportionally with depth, so the lower portion of the dam has greater water pressure exerted upon it. The increasing thickness of the lower dam also helps it support its own weight.
