Answer:
The answer is A) River delta
Explanation:
River deltas are formed by the deposition of sediment carried by rivers.
Answer:
- decreases
- inverse proportionality
- 1 A
Explanation:
Just take my word for it lol:)
It is the hottest at the mid ocean ridge because new crust is formed from the lava.
Answer:
B
Explanation:
Friction always eventually stops whatever is in motion.
Answer:
Amplitude = 0.02m
Frequency = 640 Hz
Wavelength, λ = 0.5m
v = 320 m/s
Explanation:
Given the wave equation :
y=0.02 sin2π/0.5 (320t - x) where x and y are in
meters and t is in second
Comparing the above relation with the general wave equation :
y(x, t) = Asin2π/λ(wt - kx)
The amplitude, A = 0.02
From the equation :
2π/0.5 = 2π/λ
λ = 0.5 m
320t = vt
Hence, v = 320 m/s
Recall :
v = fλ
320 = f * 0.5
f = 320 / 0.5
f = 640 Hz
