yea because the potential across the capacitor is 0

I think it's a wrong answer by the book honestly.

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?

So is my attempt correct

use equations of kinematics

Homework Statement [/B] 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 energy 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)...

I got the graph and it looks symmetric to Y axis with y=0.16 m at t=0

At t=0,y is 0.16m

My mistake...sorry

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...

Okay

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...
