The answer would be B because humans cannot see electrons so we visualize the electrons due to the theory
F = m.a
a = v^2 / r
a = 12^2 / 6.0
a = 24 m/s^2
F = 55 × 24
F = 1320 N
Here are a list of items I found.

Any gas in the atmosphere that absorbs and emits thermal infrared radiation is referred to as a greenhouse gas (GHG). These are the primary causes of the greenhouse effect, which causes the Earth's temperature to rise. Earth is warmer because less heat radiates into space.
Answer:
a. 4v
Explanation:
Alf moves with speed v
Alf travel during the same amount of time that is Δt = (1/4)s
v = (1/4)s / Δt = s / 4 Δt
s / Δt = 4 v
Beth travels a distance s during time Δt,
speed of Beth = s / Δt = 4 v .
