Answer:
D. the distance and direction to the water fountain
Explanation:
To describe the position of a water fountain relative to where one is standing, the distance and direction to the water fountain must be known.
This quantity is known as the displacement.
- Displacement is a vector quantity with both magnitude and direction.
- To specify the magnitude of a displacement, we use the length of path and in this case the height or sometimes the distance.
- The direction attribute distinguishes distance from displacement
- The perfect quantity to solve this problem is the displacement and it specifies the distance of the path and the direction traveled.
Answer:
As the atomic number is equal to number of protons in an atom , so the atom having 15 electons has atomic number 15.

Answer:
Clouds
Explanation:
Clouds float in the sky but do not have wings like a bird or plane.
Clouds drop rain, or "cry," but do not have eyes like an animal.
When clouds are overhead, they block the sun and thus create an area of darkness.
Answer:
(a) 6.8 x 10^5 Nm^2/C
(b) 1.47 x 10^5 Nm^2/C
(c) 5.3 x 10^5 Nm^2/C
Explanation:
According to the Gauss's theorem
Electric flux = Charge enclosed / ∈0
(a) Charge enclosed = 6 x 10^-6 C
So, Electric flux = (6 x 10^-6) / (8.854 x 10^-12) = 6.8 x 10^5 Nm^2/C
(b) Charge enclosed = -1.3 x 10^-6 C
So, Electric flux = (1.3 x 10^-6) / (8.854 x 10^-12) = 1.47 x 10^5 Nm^2/C
(c) Charge enclosed = 6 x 10^-6 + (-1.3 x 10^-6) = 4.7 x 10^-6 C
So, Electric flux = (4.7 x 10^-6) / (8.854 x 10^-12) = 5.3 x 10^5 Nm^2/C
