Answer to Question #59035 in Differential Equations for ABJ

Question

2 The differential equation for the curve given by the segment joining point Q(x,y) and the point of intersection of the normal at Q with the x –axis is bisected by the y –axis is given by

(a) 2y+x dx/dy=1/2y


(b) y+x dx/dy =1/2y

© y+x dx dy=1 3y

(d) y+3x dx/dy=1/2y
4 For a particular element the rate of change of temperature(T) with respect to volume (V) is proportional to the vapor temperature and inversely proportional to the square of the volume, this phenomenon as a differential equation is

(a) dT/dV=kT/V^2


(b) dT/dV=kT/2V^2

© 2 dT/dV=kT/V^3

(d) dT/dV=3 kT/V^2
