Answer:
C. The number of positive and negative charges can be the same.
Explanation:
The northward components of the resultant displacement is 40.96 m and the westward components of the resultant displacement of the bird from its nest is 28.68 m.
<h3>
Displacement of the bird</h3>
The displacement of the bird is the change in the position of the bird.
<h3>Vertical component of the bird's displacement </h3>
Vy₁ = -25 m x sin(55)
Vy₁ = -20.48 m
Vy₂ = 75 m x sin(55)
Vy₂ = 61.44 m
Total vertical displacement = 61.44 m - 20.48 m = 40.96 m
<h3>Horizontal component of the bird's displacement </h3>
Vx₁ = -25 m x cos(55)
Vx₁ = -14.34 m
Vx₂ = 75 m x cos(55)
Vx₂ = 43.02 m
Total horizontal displacement = 43.02 m - 14.34 m = 28.68 m

Answer:
my opi
Explanation:
Mass is like the inside of the weight. weight is just home much it weighs
It is salt water because they are two things combined together.
To solve this problem we will apply the concept of voltage given by Coulomb's laws. From there we will define the charges and the distance, and we will obtain the total value of the potential difference in the system.
The length of diagonal is given as
The distance of the center of the square from each of the corners is
The potential electric at the center due to each cornet charge is
The total electric potential at the center of the given square is
Al the charges are equal, and the distance are equal to a, then
Therefore the correct option is E.
