The third (left hand corner) since the x and y are both negative.
To solve this problem we will apply the concepts related to wavelength as the rate of change of the speed of the wave over the frequency. Mathematically this is

Here,
v = Wave velocity
f = Frequency,
Replacing with our values we have that,

\lambda = 0.68m
The distance to move one speaker is half this

Therefore the minimum distance will be 0.34m
Answer:
1.3 m/s
Explanation:
average speed = total distance/ total time
The answer is D. Products are formed from reactants by the breaking and forming of new bonds.
Answer:
An element is a pure substance and is made of only one type of atom; it cannot be broken down into a simpler substance.
