Monserrat · Answer 1

V = 4999.5 m/s

Explanation:

Given that

mass, m = 605 gm

Length, L = 0.75 m

width, b = 0.01 m

height, h = 0.03 m

frequency, f = 3333 Hz

We know that

2 Length = Wavelength

λ = 2 x L

λ = 2 x 0.75 m

λ = 1.5 m

The speed V

V = f x λ

Now by putting the values

V = f x λ

V = 3333 x 1.5 m/s

V = 4999.5 m/s
