Countries longer day for example in the Middle East could benefit more but Alaska has more night like longer night which is why it would hard to benefit from the solar panels there.

The coefficient of friction is 0.213
Explanation:
We start by writing the equation of the forces along the directions parallel and perpendicular to the incline. We have:
Perpendicular direction:
(1)
where
N is the normal reaction of the plane
is the component of the weight perpendicular to the plane, with
m is the mass
g = 9.8 m/s^2 the acceleration of gravity
is the angle of the incline
Parallel direction:
(2)
where
:
is the component of the weight parallel to the slope
is the force of friction, where
is the coefficient of friction
N is the normal reaction
a is the acceleration
In this case, the skier is moving at constant speed, so its acceleration is zero and the equation becomes:
(2)
From (1) we find
And substituting into (2)
Solving for
,

Answer:
D. The bicycle has no motion.
Explanation:
The graph represents the position of the bike versus time.
From the graph, we see that the position of the bike is constant, at 3 metres from the reference point, for the whole time: this means that the bike is not moving, so the correct option is
D. The bicycle has no motion.
From a position vs time graph, it is also possible to infer the velocity of the object, which is equal to the slope of the graph: in this case, the line is horizontal, so the slope is zero, which means that the bike's velocity is also zero.
