Answer:
α = 5 rad / s²
Explanation:
This is a rotational kinematics exercise.
They indicate the initial velocity wo = 10 rad / s
w = w₀ + α t
α = 
let's calculate
α = 
α = 5 rad / s²
The velocity, the angular relation are the same in all the points of the wheel, the velocities and linear accelerations are the ones that change
a = α r
v = w r
These resistors are in series.
Think of it of where the electrons can travel in the system. If there are multiple options for where they can travel then it is parallel, if there are no split paths (only one option) then it is series.
An example of a combination of resistors in parallel: The image you have above, but replace R2 with a wire that continues to the right to a battery. Then resistors R1 and R3 are in parallel.
None of the choices is an acceptable answer.
Light ... as well as all other forms of electromagnetic radiation ... is both. When you run light through an experiment built to detect particles ... such as photoelectric stimulation of electron emission ... the light behaves like a stream of particles. When you set up an experiment built to measure and detect waves ... like reflection, refraction, diffraction, dispersion, constructive and destructive interference ... the light does all of those things too.
Scientists would only debate the question if light absolutely positively had to be one or the other, and could not possibly be both. Such a debate isn't necessary, and scientists no longer waste their time arguing about it. Light is both.
Between Maxwell and Einstein, the wave/particle duality of light had been convincingly demonstrated well over a hundred years ago.
