Hi there!
Using the equation for the electric field produced by an infinite sheet of charge:
E = Electric field strength (150 N/C)
σ = Surface charge density (? C/m²)
ε₀ = Permittivity of free space (8.8542× 10⁻¹² C²/Nm²)
We can rearrange the equation to solve for the surface charge density (charge per unit area)
Answer:F=0.0882kg
Explanation:
The period it takes to make one revolution is 1.5 seconds / revolutions,
v = r * (change in angle / change in time)
the change in angle is 2pi, for one whole revolution. the time is 1.5 second per revolution, and the radius is 0.1.
v = (2 * pi * 0.1 cm * / 1.5second
v = 0.42m/s
a=v^2/r
a=0.42^2 /0.1 =1.764m/s2
F=ma
F=0.05*1.764
F=0.0882kg
We don't have much to go on.
The dimensions of D depend on the dimensions of N, n, and x, and we don't know what any of those stand for.
It might help if we had ever heard of 'diffastion', but we're striking out there too.
Flowing water. As a turbine is creating energy, as is a generator and a reservoir just holds still water. Flowing water can be pumped through a turbine or hydro scheme and be turned into energy. Another thing, as it says potential, it’s referring to something that could be/isn’t yet
