M = 7.0 kg, the mass of the groceries h = 1.2 m, the elevation of the bag of groceries
The bag of groceries moves a constant velocity over the 2.7-m room. At constant velocity, there is no applied force, and the kinetic energy remains constant.
At an elevation of 1.2 m, there is an increase in PE (potential energy) given by V = m*g*h = (7.0 kg)*(9.8 m/s²)*(1.2 m) = 82.32 J
<span>Here is an example, the allele for blue eyes and the allele for brown eyes are different versions of the gene for eye color. Alleles are located at the same genetic locus . </span>
