Passengers in an aircraft are subject to the Normal and Gravity Force acting on them at a low 'orbit', so tiny that it can be many times compared to the same surface of the earth when speaking in general terms.
In a high orbit space vehicle or in the same space, said force decreases considerably or simply disappears, generating the sensation of weightlessness.
Remember that the Force of Gravity is given under the principle
Where,
G = Gravitational Universal constant
M = Mass of the planet
m = mass of the object
r = Distance from center of the planet
When the radius grows considerably the gravitational force begins to decrease.

Answer:
D) They most likely died from not wearing a seatbelt.
Explanation:
Their death was caused by a "motor vehicle" (that's what MV stands for in this case). The most logical answer would be D.
Answer:
See below...
Explanation:
Let’s express ⟨α⟩ in terms of ωi , ωf , and Δt. and torque in terms of It , ωi , ωf , and Δt.
STEP 1.
The rate of change of angular velocity is Angular acceleration.
The net change in angular velocity is Average angular acceleration divided by the elapsed time.
⟨α⟩ = ω f −ω i/Δt
STEP 2.
Torque is assumed this way
dω
τ = I ----
dt
.
⟨τ ⟩ = I t (ω f −ω i )/Δt
