Well, my German isn't as sharp as it used to be, but it looks like you're supposed to use the symbols at the top and draw two circuits ... one where the switch is closed and the light is shining, the other where the switch is open and the light is out.
That should be pretty easy for you. Just hook up one battery, one switch, and one light, all in series. Then opening and closing the switch makes the light go on and off.

Explanation:
Given
balloon is rising with a speed of 
Person throws a ball out of basket with a horizontal velocity of 
Considering upward direction to be positive
When ball is thrown it has two velocity i.e. in upward direction and in horizontal direction so net velocity is
Direction of velocity
where 
is angle made by net velocity with horizontal .
An object thats NEGATIVELY charged has more electrons than protons, An object thats POSITIVELY charged has less electrons than protons, An object that NOT charged has the same number of electrons and protons.
Hi there!
A neutral metal sphere is comprised of both ELECTRONS and PROTONS.
Recall that electrons have a NEGATIVE (-) charge, and protons have a POSITIVE (+) charge.
Opposite charges attract, and like charges repel.
In this instance, the positively-charged rod will cause the electrons in the neutral metal sphere to move towards the side facing the rod (opposite charges attract), which causes the two to be attracted to one another.
