Answer:
resistances is inversely proportional to the area of cross section of the conductor
Answer:
0.10839 m
Explanation:
= Atmospheric pressure = 1 atm = 101325 Pa
= Total pressure at bottom of mecury = 1.2 atm
g = Acceleration due to gravity = 9.81 m/s²
h = d = Depth of mercury
= Density of mercury = 
= Density of water = 
Pressure at the bottom is of the cylinder is given by
Pressure at the bottom of mercury is
The depth of the mercury is 0.10839 m
Answer
correct answer is C
Head-to-tail method
Here head-to-tail method is employed to determine resultant of vectors.
Let horizontal component be 1 and let vertical component be 2
To add these two vectors. Move vector 2 until its tail touches the head of 1. The tail of resultant of these two vectors touch the tail of vector 1 and head of resultant vector will touch the head of vector 2.
A chemical property is a change in classification in matter I think
Since it is restricted at both ends, λ/2 = length of string
λ/2 = 1.5m
λ = 1.5*2 = 3m
