What factors affect angular momentum?

Angular momentum depends on the rotational velocity of an object, but also its rotational inertia. When an object changes its shape (rotational inertia), its angular velocity will also change if there is no external torque.

have a nice day

Explanation:

The angular momentum of an object moving in a circle with radius 'r' is the product of the mass, velocity or speed of rotation, and the radius of the circle. Newton's first law tells us that unless there is a net torque, or twisting force, on the body that is rotating, angular momentum will be conserved.

the answer would be d

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
