Physics: Post your doubts here!
The brightness of fringes increase by 1)Intensity /enrgy/powerrating of the source inciedenting light on double slits increasees 2)Decrease the distance bw the double slit 3)E=1/Lamda so decrease the wavelentgh and Intensity will increase . 4)Increase the WIDTH of both slits without changing the... -

Vertical height is 8.6 by 2as=v^2-u^2 V=15cos60 u=0 so we get s=8.6(vertical height) So we find out the time As verticla component of velocity is zero at top Highest point so s=ut+.5x9.81xt^2 8.6=(0)t=.5x9.81xt^2 we get T=1.32 So horizontal component is 6.15/1.32=4.64m/s In c part the important... -

First of all find the resistance of the individual resistor which is 38.4 First is open close close so No current as the first switch is open so no power then Close Close open Current passes but as Switch two is open so Current bypasse the resistor B so the resistance is not taken into account... -
