How is p-n-p transistor biased to operate in the active mode

Shown from explanation.henc2 we

Explanation:

For the transistor to work in the active mode meaning for it to conduct normally, the p- side has to the connected to the positive side of the battery and the n- side the negative terminal of the battery.

Hence we have two batteries such that both ends are connected to the positive terminal and the negative side connected to the middle the n- side of the transistor.

gravity

explanation:

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
