What’s the best way to survive an elevator crash

stand with your knees bent to absorb the impact, like a skydiver. Theoretically, your legs would flex as you and the elevator touched down, spreading your body's deceleration over a longer period (impact force is proportional to speed and mass, and inversely proportional to time and stopping distance the longer the time spent stopping, the less the force). The effectiveness of this approach at high speeds, however, remains unclear, and research shows that you would likely be subjecting your knees and legs to greater injury risk at low speeds. This approach also keeps your body parallel to the lines of force, which increases the chance of bone breakage as you crumple to the floor under high load.

Hope this helps have a good day

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff
