A system consists of N very weakly interacting particles at a temperature T sufficiently high so that classical statistical mech
anics is applicable. Each particle has a mass m and is free to perform one-dimensional oscillations about its equilibrium position. Calculate the heat capacity of this system of particles at this temperature in each of the following cases:

Answer:
So the fraction of proeutectoid cementite is 44.3%
Explanation:
Given that
cast iron with 0.35 % wtC and we have to find out fraction of proeutectoid cementite phase when cooled from 1500 C to room temperature.
We know that
Fraction of proeutectoid cementite phase gievn as
Now by putting the values
So the fraction of proeutectoid cementite is 44.3%
Answer:
The electric field to balance the weight is approximately equals to 3.49x10^5 Newton/Coulumb
Explanation:
In order to be stationary position, magnitude of the total force due to electric field should be equal to the gravitational force that is,
where
where <em>q</em> is the charge of the droplet and E is the electric field. On the other hand
where <em>m</em>,<em>V ,d</em> and<em> r</em> are the mass, volume, density and radius of the oil droplet respectively and <em>g </em>is the gravitational acceleration (g=9,80665 m/sn^2). By using the first equation and solving it for the electric field we can write,
(Note: d=0.85 x 10^-3 kg/cm^3 and the unit of electric field is Newton per coulumb (N/C))
