When two mechanical waves have a displacement in the same direction, and they overlap, what will the resulting wave look like and why?
a. the new wave will have the same displacement as the original waves due to constructive interference.
b. the new wave will have a smaller displacement than either of the original waves due to destructive interference.
c. the new wave will have a greater displacement than either of the original waves due to constructive interference.
d. new wave will have the same displacement as the original waves due to destructive interference.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

you know they are heterozygous for a trait because they have it as jj or jj.
