22 ) Sunbed - it uses UV rays
23 ) A - it is assumed that light reaches in no time, however it still takes very less time
26 ) D - due to the positive charge, the surface opposite to the ball will become negative and thus the other side of the ball will become positive
32 ) B - Due to large current flow, the fuse melts and does its work
33 ) C - the electrons movement is from left to right , however the conventional current is from right to left , using the flemming's left hand rule, the electrons are deflected towards the bottom
35 ) C - as the direction of the magnet is reverse, the pointer moves to the left but as the movement of the magnet stops the pointer comes back to zero
37 ) B - lamp P is getting the full current , but lamp Q and R are each getting half of the whole current.
