True because all switches use contacts to start or stop the flow of electrons in a circuit
The area under the velocity time graph is 125 m and the meaning of the area is displacement.
<h3>
What is area under velocity - time graph?</h3>
The area under a velocity time graph represents the displacement of the object.
total area of the graph = A1 + A2
total area of the graph = ¹/₂ (base₁)(height₁) + ¹/₂ (base₂)(height₂)
total area of the graph = ¹/₂(4)(40) + ¹/₂(3)(30)
total area of the graph = 125 m
Thus, the area under the velocity time graph is 125 m and the meaning of the area is displacement.

Explanation:
1) For a positive point charge, the lines radiate outwards
for a negative point charge, the lines converge inwards
2) F = 2.3 X 10^-26 N
k = 9 X 10^9 N.m²/C
q1 = q2 = e = 1.6 X 10^-19 C
r = ?
F = kq1q2/r²
r² = kq1q2/F
r = √[kq1q2/F ]
r = √0.0100
r = 0.10m
The two protons are 0.10 m apart
3) The unit if electric field intensity is Newton-per-coulomb N/C

![= 550 * 10^{-9}\] m. D = 3.50*10^-6 m.](https://tex.z-dn.net/?f=%20%3D%20550%20%2A%2010%5E%7B-9%7D%5C%5D%20m.%0A%0AD%20%3D%203.50%2A10%5E-6%20m.)
Then you need to find x when n=1
or
≈θ for θ<<1 , so θ=
