Answer:
Below
Explanation:
To find the wave speed of a wave you can use this formula :
wavespeed (v) = (frequency) x (wavelength λ)
Plug in our values :
v = (10Hz) x (2m)
v = 20 m/s

Answer:
3.55m/s^2
Explanation:
S = ut + 1/2at^2
S = 48m, u = 0, t = 5.2
48 = (0×5.2) + (1/2 × 5.2^2)a
48 = 13.52a
Dividing through by 13.52
a = 48/13.52
a = 3.55m/s^2
Its quite hard to give you facts over this but just type into google facts about the sonar/lunar eclipse.
