When two objects collide there will be a force acting on them both and their individual kinetic energies and momenta may alter. As you know already, energy is always conserved but in a collision some, or all of the kinetic energy may be ... of the same mass and traveling at the same speed but in opposite directions collided ...
Since the grains are not connected together, it's every grain for himself when they're dropped into the water.
The density of each grain is greater than the density of water, so each grain on its own sinks to the bottom.
The reason why a CUP or a BAG of rice has less density is because the grains don't all fit together perfectly, and 15% or 20% of the volume in the cup or bag is air, not rice grains.

Answer:
Hence lowest (nonzero) frequency that gives destructive interference in this case = 3400 Hz
Explanation:
Since, the two are in out of phase,
their path difference is
d= nλ
Given d1= 2.75 m
D= 3.90 m
d_2= 2.76 m
2.76-2.75= 1×λ
λ= 0.01 m
0.01= 1*λ
λ =0.01
frequency ν = v/λ = 340/0.01
f= 3400 Hz
Hence lowest (nonzero) frequency that gives destructive interference in this case = 3400 Hz
