Answer:
7.65 m
Explanation:
= Initial pressure = 0.03 atm
= Final pressure = 1 atm
= Inital radius = 21 m
= Intial volume of gas =
= Final volume of gas =
= Initial temperature = 200 K
= Final temperature = 323 K
From ideal gas law we have
The radius at liftoff is 7.65 m
Transformer contains two coils: primary and secondary. They allow change of voltage to lower or higher value. In first case we have step-down and in second case we have step-up transformer.
Formula used for transformer is:
Where:
N1 = number of turns on primary coil
N2 = number of turns on secondary coil
V1 = voltage on primary coil
V2 = voltage on secondary coil
In a step-down transformer primary coil has more turns than secondary coil. So the ratio 1:29 means that for each turn on secondary coil we have 29 turns on primary coil.
We can solve the equation for V2:
Secondary coil provides voltage of 4.14V.
