Answer 2

$\huge \mathfrak{Answer}$

1) :- The booster is dropped to fall back to Earth once its fuel is expended, a point known as booster engine cut-off (BECO). Following booster separation, the rest of the launch vehicle continues flight with its core or upper-stage engines.

2) :- A fire spreads by transferring heat energy in three ways: Radiation, Convection, and Conduction.

3) :- To go fast, I needed to minimize the surface area of skin and suit making contact with the slide. Basic speed-chuting position involves crossing your ankles, tensing your core, and arching your back so that there are only three points of contact with the slide: the shoulder blades and a single heel.
