Here's my guesses.
1 sea stack ... A2 inlet ... E3 sand spit ... F4 sea arch ... B (looks like a land arch made by the sea ... ?)5 lagoon ... C6 barrier island ...A7 bay ... D8 sea cliff .... J9 sea cave .... G10 tombolo .... no idea
That's a lot of work for 9 points !!!!
Answer:
ocean waves and ripples from a stone being thrown in a pond.
Explanation:
Total energy before the toss:
Total energy at the roof:
Energy must be conserved so :
If v₁ is the initial velocity and v₂ is the final velocity, which is zero at the roof:
Answer:
given,
volume = 133.7 ft³
1 ft³ = 0.0283 m³
133.7 ft³ = 133.7 × 0.0283 = 3.784 m³
mass = 268 kg
1 kg = 2.204 lb
268 kg = 268 × 2.204 = 590.672 lb
weight of the fuel = 268 × 9.8 = 2626.4 N
1 N = 0.2248 lbf
2626.4 N = 2626.4 × 0.2248 = 590.414 lbf
ρ = 70.82 kg/m³
specific volume =
= 0.226 ft³/lbm
Answer:
Explanation:
given,
speed of length of travel = 0.86 c
length of tunnel = 88 m
Assume length of super train = 205 m
An observer at rest in the tunnel's reference frame will observe the train's length to be contracted:
L' = L₀ / γ
L' is the length the observer measures,
L₀ is the proper length of the train
