An organism which has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.

Kinetic Energy

=>It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

Potential Energy 

=>potential energy is the energy held by an

 object because of its position relative to other

 objects, stresses within itself, its electric

 charge, or other factors.

<h2>Difference:</h2>

=>Potential energy is a stored energy on the other hand kinetic energy is the energy of an object or a system's particle in Motion.

The law of reflection is quite useful for mirrors and other flat, shiny surfaces. (This sort of reflection is called specular re

Sever21 [200]

Answer:

Explanation:

Suppose initially the plane was horizontal and light was reflected back at some angle θ from the normal .

Now the reflecting surface is twisted so that is becomes inclined at angle alpha .

The reflected light will be deviated from its original direction by angle

2 x alpha .

Similarly when the reflecting surface is further twisted so that it becomes inclined at angle beta then again the reflected beam will deviated by angle

2 x beta

Hence angle between these two reflected beam

= 2 beta - 2 alpha

= 2 ( β - α )

So, angular separation between the rays reflected from the two surfaces

= 2 ( β - α ) .
