To solve the problem it is necessary to apply the concepts related to heat flow,
The heat flux can be defined as
Where,
k = Thermal conductivity
A = Area of cross-sectional area
d = Length of the rod
Temperature difference between the ends of the rod
Thermal conductivity of copper rod
Area of cross section of rod
Temperature difference
length of rod
Replacing then,
From the definition of heat flow we know that this is also equivalent
Where,
Mass per second
Latent heat of fusion of ice
Re-arrange to find 
Therefore the mass of ice per second that melts is 0.032g
Answer:
no, otherwise they just cause a side effect on our lives
A diod can act as a capacitor
the deplition region in diod acts as a capacitor as it also stores energy similar to capacitor in electric field.
Answer:
Because the zinc is reluctant
Explanation:
A leclanche cell contains a conducting solution (electrolyte) of ammonium chloride, a cathode (positive terminal) of carbon, a depolarizer of manganese dioxide (oxidizer), and an anode (negative terminal) of zinc (reductant).
As the Zn2+ ions move away from the anode, leaving their electrons on its surface,
Zn → Zn2+ + 2e−
the anode becomes more negatively charged than the cathode. When the cell is connected to an external electrical circuit, the excess electrons on the zinc anode flow through the circuit to the carbon rod, the movement of electrons forming an electric current.
