Answer:
Convergent boundaries,over time,a rift valley will form.
Explanation:
The picture shows 2 plates moving apart,and a shallow "valley"is also noticeable.
Mark me brainliest if I helped:D
Answer:
θ = 14.45º = 0.252 rad
Explanation:
The expression that describes the phenomenon of diffraction is
a sin θ = m λ
Where a is the width of the exit opening in this case the width of the door, Lam is the wavelength, m the diffraction order for destructive interference,
Let's use the relationship between the speed of the wave is the producer of its frequency by the wavelength
v = λ f
λ = v / f
λ = 344/1220
λ = 0.282 m
sin θ = m λ / a
For the first destructive interference m = 1
sin θ = 1 0.282 /1.13
sin θ = 0.24956
θ = sin-1 (0.24956)
θ = 14.45º
We pass radians
θ = 14.45 (pi rad / 180º) = 0.252 rad
Force = 202,200 x 1.5 ms.q
Force = 303,000 newtons
Answer:
B 8-9 because you had to subtract that number or simplify. then your answer is 8-9
