Fenomeno de resonancia.
Espero que estoy te ayude :)
Answer:
(a) Since net charge remains same,after immersion Q is same
(b) I. 14.56pF ii. 3.05V
(c) ΔU = 5.204nJ
Explanation:
a)
C = kεA/d
k=1 for air
ε is 8.85x10-12F/m
A = .0025m2
d = .125m
C = 8.85x10-12x.0025/.125 = 1.77x10-13F = 0.177pF
Q = CV = .177pF * 244V = 43.188pC
Since net charge remains same,after immersion Q is same
b)
C = kεA/d, for distilled water k is approx. 80
Cwater = Cair x k
=0.177pF x 80 = 14.16pF
Q is same and C is changed V=Q/c holds. where Q is still 43.188pC and C is now 14.16pF, so V = 43.188pC/14.16pF = 3.05V
c) Change in energy: ΔU = Uwater - Uair
Uwater = Q2/2C = (43.188)2/2x.177pF = 5.27nJ
Uair = Q2/2C = (43.188)2/2x14.16pF = 0.066nJ
ΔU = 5.204nJ
Convert 1 atom into 10 electrons (I think)
Answer:
A is a battery
B is a light
C is a resistor
D is a closed switch
thank you for this question, I love circuit diagrams
Explanation:
Heat is transferred by a fluid's macroscopic movement, which is known as convection. Weather systems and forced-air furnaces both use this form of transmission. Thus, option A is correct.
<h3>What Convection method of heat transfer warms?</h3>
Convection, as heat is transmitted through the sand's solid structure. Conduction, as the air particles that come into contact with the hot sand travel more quickly.
The heat is transferred inside the fluid during convection. Heat transfer in radiation happens by electromagnetic waves without the use of particles.
Conduction, as heat is transferred using electromagnetic waves Convection, since heat is transferred by air particles without the usage of a medium.
Therefore, Convection, because heat is transferred through the solid sand.
