    HI FREINDS HOW WAS THE PHYSICS ATP GCSE O LAVEL?

    For the first i wrote that the measuring instrument might dip in water or strike with edges and for (b) i wrote that measure the l using a string and then measure the length of string :p

    Just like line 1. Refract towards normal by drawing the normal at surface, and then away from normal when it leaves.

    1) You take a U shaped magnet. Pass a wire carrying current between them. A force is generated on the wire due to change in magnetic flux as the the magnetic field of wire cuts the magnet field of U shaped magnet. Direction of force can be found using a Left Hand Rule. 2) If the magnetic field...

    They only ask about the Advantages in Parallel: I) Less internal resistance so they don't heat up and more brighter II) Last longer III) If one blows, other keep working.

    Yup. We charge the rods by friction. We bring it closer to an electroscope. There will be a deflection/divergion in the electroscope if it's charged.
