Answer there really are not any examples to use
Explanation:
The distance that is measured in the most accurate manner is letter c. This is because centimeters is the smallest unit of measurement. The given choices show that the first two measurements are expressed with decimal places but the graduations of each are greater compared to centimeters.
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.
The RC time constant, also called tau, the time constant (in seconds) of an RC circuit, is equal to the product of the circuit resistance (in ohms) and the circuit capacitance (in farads), i.e.

Here,
R = Resistance
C = Capacitance
Replacing we have that



Therefore the time constant of this circuit is 
A galaxy because that is the largest group and contains many things.
