Explanation: I’m not sure tho
Take Off Your Boot, And Shake Your Boot
The minimum frequency is

while the maximum frequency is

Using the relationship between frequency f of a wave, wavelength

and the speed of the wave v, we can find what wavelength these frequencies correspond to:


So, the wavelengths of the radio waves of the problem are within the range 188-545 m.
Yes, a puddle of water is an object in motion.
Where the m1 and m2 is the mass of two object. U1 and U2 are the initial velocity of hockey pucks. V1 and V2 are the final velocity of Hockey Pucks.
m2=2kg The initial velocity of both pucks are 0. The v1=8m/s. All you have to do now is find v2
0=4-2v
-4=-2v
v=+2m/s
Answer: +2
