If a diode is connected with P junction with higher voltage and N with low voltage then why is there a potential rise as opposed to the decrease in potential like in battery?

A glass slab of refractive index n=2 has left spherical of radius 10cm and right surface plane.From both surfaces refraction as well as reflection takes place.A point of object P is placed at a distance 15cm from point O1.
Mark the correct option
(A)two images are...
The only thing I had thought for this was to use work enrgy theorem because no other informations were provided
I thought of using- W gas+W atm+W spring+W gravity=KE(final)-K.E (Initial)
However since the gas is heated there because of heat therefore I don't think this will apply
Homework Statement
A non-conducting piston of mass m and area of cross section A is placed on a non-conducting cylinder.
Intial height of piston is h and spring is relaxed with a spring constant k.Then,work done in displacing pistin by heating gas is (x is the displacement of the pistion)...
Homework Statement
y(x,t)=0.8/{(4x+5t)^2+5 }represents a moving pulse,where x and y are in metre and tin second.Then choose the options.
(a)Pulse is moving in positive X axis
(b)In 2 secs,it will travel a displacement of 2.5m
(c)It's maximum displacement is 0.16m
(d)It is a symmetric pulse...
I got two definitions for this enthalpy:
I)Heat change when 1 mole of a substance is completely burned or oxidised(My textbook)
2) Heat change when 1 mole of compound is completely burnt or oxidized in oxygen(From a site)
So if I had this reaction:
H2(g)+1/2 O2(g)---->H20...
