Answer:
it will show a continuous rise in value. The rise will be sinusoidal.
Explanation:
I found some missing information about this problem online. We are given the force:

Power is defined as the rate of doing work.
This is the formula:

Where P is power, W is work.
Work is defined as:

F is the force and r is the displacement.
If we assume that force is not changing (it's constant) with time we get:

Keep in mind that both force and velocity are vectors, so we have to multiply each component separately.
Finally, we get:
Answer:
A) 0.957 J

Answer:
Q = ba⁴ * ε₀
Explanation:
From Gauss's Law, we know that
flux Φ = Q / ε₀
where ε₀ = 8.85e-12 C²/N·m²
and also,
Φ = EAcosθ
The field is directed along the x-axis, so that all of the flux passes through the side of the cube at x = a. This means that θ = 0º, and thus
Φ = EAcos0
Φ = EA
E = bx² meanwhile, we are interested in the point where x = a, so we substitute and then
E = ba²
Since A = a² for the cube face, we have
Q / ε₀ = E * A
Q / ε₀ = ba² * a²
so that
Q = ba⁴ * ε₀
