Answer:
e. 7V
Explanation:
If the potential created at the point P by the first charge is 5 V, and the electric potential created by the second charge is 2 V, as the potential is proportional to the electric field created by the charges, which is linear (due to it is directly proportional to the value of the charges), we can apply the superposition principle.
In this way, we can calculate the total potential, at a point P, as the algebraic sum of the potentials created by all the charges, as if the other ones were not present.
In this case, we have:
V = V₁ + V₂ = 5 V + 2 V = 7 V
Answer:
Ionosphere
Explanation:
The thermosphere reaches 600 kilometres just above mesosphere and begins immediately above the mesosphere. This layer is where the aurora and satellites appear.
The ionosphere is the comprehensive career of the mesosphere because most of the thermosphere, located 80–400 kilometres just above ground atmosphere.
Auroras — magnificent flowing streaks of light seen in the night sky – appear in this location.
Answer:
initial velocity = 7.44 m/s (3 s.f.)
Explanation:
a = 6.24 m/s² t = 0.300 s v = 9.31 m/s u = ?
v = u + at
9.31 = u + (6.24 x 0.300)
9.31 = u + 1.872
u = 7.438
= 7.44 m/s (3 s.f.)
Hope this helps!
