The displacement should be a negative value. since your zero point is where you dropped it. The answer is C
The answer is variant C because every living organism needs water to survive. A human can live without water only 6 days, after that period the most important organs start to shut down because of the lack of water.
speed Δv = v₂ = 8.15ms⁻¹
v₁ = 0ms⁻¹
time =t = 5s
acceleration = a = speed / time taken
a = Δv / Δt ( as Δv = v₂ - v₁)
a = 8.15ms⁻¹ / 5 s
a = 1.6ms⁻²
B. 0.64 J/g-K I already did the test this was the correct answer
i'm just saying that this question makes no sense to me....but thanks for the points UwU
