Question

after the space shuttle has jettisoned its thruster and external tanks, would it be considered an open or closed system? what is the appropriate explanation to support your answer?
*the space shuttle system is made up of three main components:
*the two solid rocket boosters (srbs), which provide 80 percent of launch thrust.
*the huge rust - colored external tank (et), which feeds fuel to three space shuttle main engines (ssmes) during launch
*the orbiter itself, which serves as the crews home in space and is equipped to dock with the international space station.

a the space shuttle is an open system, because it must use fuel when the solar panels arent exposed to sunlight.
b the space shuttle is an open system, because it must change direction occasionally, expelling gases to adjust its position.
c the space shuttle is a closed system, because it only exchanges energy with its surrounding through solar panels used to provide heat.
d the space shuttle is a closed system because, it doesnt change direction after reaching its orbit, so no matter is exchanged with its surroundings.

Explanation:

An open system exchanges both matter and energy with its surroundings. The space shuttle jettisons thrusters and external tanks (matter exchange) and interacts with its environment (e.g., expelling gases for position adjustment, energy exchange). A closed system only exchanges energy, not matter, which does not apply here. Options A and C incorrectly link fuel use/solar panels or heat exchange to system type; option D claims no matter exchange, which is false.

Answer:

B. The space shuttle is an open system, because it must change direction occasionally, expelling gases to adjust its position.
