Explanation:
entropy is the randomness or disorder of a system right?
we know gases have negligible forces of attraction hence the particle move in an uphazard manner hence there great disorder as compared to liquid with low force of attraction low kinetic energy but in solid particles are held by strong intermolecular forces in fixed position where kinetic energy is low and order is greater here
Answer:
The greater the luminosity of a star, the longer its period of oscillation.
Answer:
A)Explanation:
Let object distance be u.
Image distance v = 1.06 - u
Focal length = 20 cm = .2 m
Applying lens formula
1 / v - 1 / u = 1 / f
1 /( 1.06-u) - 1 / u = 1 / .2
5 u² -3.3u - 1.06 =0
It will have two roots
u₁ = .1636 m, u₂ = .8964 m
B ) Magnification
= u = .1636m , v = .8964m
m = .8964 / .1636 = 5.48
C ) When u = .8964m ,v = .1634m
m = .1634 / .8964
=.182
Answer:
0.0360531138247 V/m
Explanation:
= Resistivity of gold = (General value)
I = Current = 940 mA
d = Diameter = 0.9 mm
A = Area =
E = Electric field
Resistivity is given by
The electric field in the wire is 0.0360531138247 V/m
