See less1(iii). The general solution of p = log ( px – y), Where , is
Ans:- $y=cx - e^c$ Explanation:- p = log(px - y) $\Rightarrow px - y = e^p$ $\Rightarrow y = px - e^p$ $\Rightarrow p = p.1 + x\frac{dp}{dx} -e^p\frac{dp}{dx}$ $\Rightarrow (x-e^p)\frac{dp}{dx} = 0$ $\Rightarrow$ p = c or $x = e^p$ $\therefore$ general solution $y = cx - e^c$
Ans:-
Explanation:-
p = log(px – y)
p = c or

c) 3 Explanation: All possible ways of arranging n particles in g phase cells According to Fermions: Number of ways of all possible arrangement = $\frac{g!}{n!(g-n)!}$ here g = 3 and n = 2 So, Number of ways of all possible arrangement = $\frac{3!}{2!(3-2)!}$ = 3
c) 3
Explanation:
All possible ways of arranging n particles in g phase cells
According to Fermions:
Number of ways of all possible arrangement =
here g = 3 and n = 2 So,
Number of ways of all possible arrangement = = 3

b) evolute Explanation: In the differential geometry of curves, the evolute of a curve is the locus of all its centers of curvature. That is to say that when the center of curvature of each point on a curve is drawn, the resultant shape will be the evolute of that curve.
b) evolute
Explanation:
In the differential geometry of curves, the evolute of a curve is the locus of all its centers of curvature. That is to say that when the center of curvature of each point on a curve is drawn, the resultant shape will be the evolute of that curve.
See less20. By using the concept of equation of a line, prove that the three points (3, 0), (– 2, – 2) and (8, 2) are collinear.
To prove that the three points (3, 0), (-2, -2), and (8, 2) are collinear, that means these three points lie on the same line. Here we need to check whether (8, 2) satisfy the equation made by the point (3, 0) and (-2, -2) or not. We know that equation of the line passing through $(x_1, y_1)$ and $(Read more
To prove that the three points (3, 0), (-2, -2), and (8, 2) are collinear, that means these three points lie on the same line.
Here we need to check whether (8, 2) satisfy the equation made by the point (3, 0) and (-2, -2) or not.
We know that equation of the line passing through and is
So, the equation of the line passing through (3, 0) and (-2, -2) is
5y = 2x – 6
2x – 5y – 6 = 0
Since the three points lie on the same line, then point (8, 2) must satisfy the equation 2x – 5y – 6 = 0
putting x = 8 and y = 2 in the above equation
2(8) – 5(2) -6 = 0
16 – 10 – 6 = 0
0 = 0
Which is true
Hence (3, 0), (-2, -2), and (8, 2) are collinear
