Answer:
If one of the parents is white and the other is brown, their offspring will be either white or brown with equal probabilities. Rabbits in this population mate randomly; thus, the probability of mating two white rabbits is the same as the probability of mating between two brown rabbits.

1m is equivalent to 100cm
1m = 100cm
        
             
        
        
        
It burns when you start your car and that conducts electricity which burns it.
        
                    
             
        
        
        
 Density = (mass) / (volume), no matter how large or small the sample is.
We can't calculate the density, because you left out the number for the volume.
Also, you didn't tell us the unit for the mass of 180. 
a).  If the mass is 180 grams, then the density is  
                               (180 gm) / (volume) .
b).  No matter how many pieces you crush it into, and 
no matter how large or small a piece is, its density is 
the same.  (I just wish we knew what the density really is.) 
c).  A piece may have 80 grams of mass.  It doesn't "weigh" 80 grams.
Since the density of the whole rock is  (180 gm) / (volume),
the density of any piece of it is  (180 gm) / (volume).
Multiply each side by (volume):   (Density) x (volume) = 180 gm
Divide each side by (density):        Volume = (180 gm) / (density)
We can't calculate the volume of an 80-gm piece, because 
we don't know the density.  (That's because you left the volume
out of the question.)
        
             
        
        
        
You can see the periodic motion as the projection over the diameter of a point moving with a circular motion.
The Amplitude will be the radius of the circumference and ω is the angular frequency (or speed) for both motions.
In the periodic motion, you will have maximum velocity at the center and it will be zero at the extremities, where the projection changes direction, while the acceleration will be maximum at the extremities and zero at the center.
The displacement will then be:
x(t) = A · cos(ωt)
And from this (using a little bit of calculus):
v(t) = A · ω · sin<span>(ωt)
a(t) = </span><span>A · <span>ω</span>² · cos(ωt)</span>
