Explanation:
Leclanche cell : Leclanche cell is also known as dry cells (fig 2). It contains an electrolyte of ammonium chloride. Carbon acts as a cathode while zinc is an anode.

It consists of a zinc rod and a copper vessel (in fig 1). It can be seen that a zinc rod is put in dilute sulfuric acid which is contained in a porous pot. Daniel cell works on the principle of the redox reaction. The electrons pass form zinc rod to wire. Then it passes to the copper rod. Thus, a current is produced.

Answer:
pressure=height × density×acc due to gravity
so
pressire is directly proportional to height hence it decreses with decrease in height
here air column height is measured upside down so decreases witn increment
Nope Copper is a better conductor
Answer:
Acceleration of that planet is 30
.
Given:
initial speed of hammer = 0 
time = 1 s
distance = 15 m
To find:
Acceleration due to gravity = ?
Formula used:
Distance covered by hammer is given by,
s = ut + 
s = distance
u = initial speed of hammer
t = time taken by hammer to reach ground
a = acceleration
Solution:
Distance covered by hammer is given by,
s = ut + 
s = distance
u = initial speed of hammer
t = time taken by hammer to reach ground
a = acceleration
u = 0
t = 1 s
s = 15 m
a = g
Thus substituting these value in above equation.
15 = 0 + 
g = 15 × 2
g = 30 
Thus, acceleration of that planet is 30
.
So that the correct representative of the people gets elected to head the people- so that a person who is thought to be capable enough to rule over people and take the correct decisions may be representative to the people.
