Answer:
Below!
Explanation:
The citric acid in the lemon acts as an electrolyte, a solution that conducts electricity. The zinc nail sheds electrons as electrically charged ions into the acid (a process called “Oxidation” because the material loses electrons). ... The average lemon output is . 9 volts at .

I cant really say but i believe it is called extinction
Answer:
a) KE = 0.0857Joules
b) height = 0.073m
Explanation:
The rotational inertia of the rod at an axis passing through the fixed end is given by:
I = Icm + my
I= 1/12 mL^2 + m(L/2)
I= 1/12 ×0.12×(0.75)^2 + 0.12× (0.75/2)^2
I = 5.625×10^-3 + 0.01688
I = 0.0225Kg/m^-2
a) KE = 1/2 Iw^2
Where I= rotational inertia
w= angular speed at lowest point
KE = 1/2 × 0.0225 ×(2.76)^2
KE= 0.0857 Joules
b) Ki + Ui = Kf + Uf
Ki = Uf - Ui = 0
mgh = K
0.0857= mgh
h = 0.0857/( 0.120× 9.8)
h = 0.0857/ 1.176
h = 0.073m
They begin as dark clouds and cosmic dust
