a genotype is a set of genes located in our dna which is accountable for a specific or certain trait. a phenotype is the physical result or characteristics from that given trait.
The greater the speed of two identical masses, the greater the kinetic energy. So, the mass that is traveling twice as fast as the other has much more kinetic energy. The formula for kinetic energy is KE=m*v^2 (kinetic energy equals mass times velocity squared), and velocity is the same as speed in this case because it is squared. So, the mass traveling twice as fast has 4 times the kinetic energy, because 2 squared=2*2=4.
Answer: The mass traveling twice as fast has four times the kinetic energy.
C should do the trick but I wouldn't count on it ive only been studying for a day now on this
