Answer:
1/2m or 0.5m
Explanation:
The formula to find the speed of a wave is given by:
V = frequency x wavelength
To find the wavelength, make the wavelength the subject of the formula
Therefore, wavelength = velocity ÷ frequency
I'm not sure but I think that if objects are closer (less distant), than the gravitational pull is stronger. I'm sorry if I couldn't really help I remember learning about this kind of.
The density will always be the same.
