Answer:
5.0 × 10⁵
Explanation:
Quantity of charge Q = It
V= IR
I = V / R
Q = Vt/R
Q = ne
ne = Vt/R
n, number of K⁺ ions = Vt / Re
V = 80 × 10 ⁻³
t = 1 × 10⁻³ s
R = 1 × 10⁹ Ω
e = 1.6 × 10⁻¹⁶C
n, number of K⁺ ions = (80 × 10 ⁻³ V × 1 × 10⁻³ s ) / (1 × 10⁹ Ω × 1.6 × 10⁻¹⁹C) = 5.0 × 10⁵
Work = force x distance
Work = 455N (weight force) x 1.5m (distance)
Work done = 682.5J
Hope this helped!
I think those are it but I can't find the other one but I'll keep looking
2.tidal current
3.tidal force
B. wind.
Sun (solar) --> plants (photosynthesis) --> cola (chemical) --> heat (combustion) --> steam --> turbine (kinetic) --> generator (electric)
There is no wind.
