Answer:

780ms^{-1}

Explanation:

The equation used to find the speed of a waveform is V = f λ

You are given

f = 1200Hz

λ = 0.65m

and need to find V

Plug in your values to the equation

V = 1200 * 0.65

V = 780ms^{-1}

givi [52]

Answer:

2.5m/s^2

Explanation:

Step one:

given

distance = 20meters

time = 2 seconds

initial velocity u= 0m/s

let us solve for the final velocity

velocity = distance/time

velocity= 20/2

velocity= 10m/s

v^2=u^2+2as\\\\10^2=0^2+2*a*20\\\\100=40a

divide both sides by 40

a= 100/40\\\\a=10/4\\\\a= 5/2\\\\a= 2.5m/s^2
