but i am treating every length element of the curve as a part of a circle of appropriate radius. so i am treating the curve as a conglomerate of numerous circular elements just in the area derivation.

but where is the derivation of the length of curve wrong?

The area of a polar curve is given by A=(1/2)∫ r2 d (theta). this can be interpreted as δA= ∏r2δ(theta)/2∏ (treating the area element as the area of a sector of a circle with angle δ(theta).) taking limit of δ(theta)→0, dA= ∏r2 d(theta)/2∏=1/2 (r2d(theta) ) there fore A=1/2∫r2 d(theta)...

so what is the explanation or correct thought process for this?

hi, i was wondering, for a black hole, as everyone knows,the escape velocity is greater than light. this means that the information about the existence of the black hole in terms of light never reaches the observer. so if the black hole were the cease to exist at an instant of time, the...

hi, since light is energy moving through the fabric of space time at velocity c , it should lose energy due to gravitational waves. doesn't this mean that the light from a distant galaxy would keep decreasing in frequency? further more this would imply that light that was originally emitted as...

the double slit experiment highlights the wave-particle duality. at the time of creation and annihilation,the particle behaves as a particle.and in between as a wave.so the after creation,the particle travels as a wave and since there are two possibles paths(two slits) the wave (and wave...

hi all, this is a very basic question. apart from maxwell's equation, why else is the speed of light a universal constant?

there are two ways time can be stopped. 1>at the speed of light: using einstein's formula, if v=c then denominator becomes 0.so naturally time stops. this explains the immense stability of photons despite their high energy density. 2>at a region of high gravitational force such as within the...

the bodies will revolve around the common center of gravity.

in my opinion theoretically the battery would be possible but highly unstable due to the high + charge on the atoms.also removing so many electrons isn't a joke.

in what scale can we consider the uncertainty principle?can it be considered in the non atomic scale?

why does the direction of light change during refraction if the speed changes?how are speed and direction related?
