Russian Astronaut, Elena Serova, is preparing her breakfast burrito on the International Space Station. How much force must her comrade, Alexander Sam, apply to pass her a 0.25 kg packet of salsa with an acceleration of 0.5? a2 N
b1 N
c0.125 N
d0.5 N

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 think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

the answer to this is proletariats.

hope this : )
