6. In a competition, Mike lifts a 100 kg weight from the floor in 2 sec. Brian also
lifts a 100 kg weight to the same height above the floor, but takes him 3 sec. to do so.
a. Who does more work?
b. Who generates more power?

Explanation:

Analogy:

Who does more work:

Work done is defined as the product of force and distance. Work is done when force moves a body in a particular direction.

In this case, work done is the same thing as the potential energy of the weight.

           Work done = potential energy = m x g x h

 Mass of weight = 100kg for both Mike and Brian

g is the acceleration due to gravity

h is the height

Since they lifted the weight through the same height;

        Work done by Mike = 100gh

        Work done by Brian = 100gh

Both Mike and Brian does equal work

Who generates more power:

Power is the rate at which work is done;

          Power  =

Power generated by Mike =  = 50gh

Power generated by Brian = = 33.33gh

We can see that Mike generated more power

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
