The distance is the total distance she walked which is 16 meters adding the 6 meters to the corner and 10 meters to her friend's apartment. Her displacement is the distance from her original starting point so you set up a triangle with side lengths of 6 and 10 and solve for the hypotenuse which gives you a displacement of 11.66 meters.
Answer:
Because of the vibration of the string. since it is vibrating it will make the other air molecules vibrate as well and air vibrating is basically a sound wave.
Formula for calculating [Average Atomic Mass] of Pb (Lead):AAM of [element] = (Mass of isotope) * (Relative abundance) and you can repeat the "(Mass of isotope) * (Relative abundance)" part for each isotope! Therefore...AAM of Pb=(203.97302)(0.014)+(205.97444)(0.241)+(206.97587)(0.221)+(207.97663)(0.524)AAM of Pb = 207.21688371 amu [OR] 207.2 amu on most periodic tables.
A skater can spin faster by pulling her arms closer to her body or spin slower by spreading her arms out from her body due to conservation of angular momentum.
What is conservation of angular momentum?
- Conservation of angular momentum is a physical property of a spinning system such that its spin remains constant unless it is acted upon by an external force, or to put in another way, the speed of rotation is constant as long as net torque is zero.
- Angular momentum, sometimes also referred to as spin, is determined by an object's mass, its velocity and distance of an object's mass from the point of rotation.
- The nearer the mass is to its axis point or the more consolidated it is around that axis the greater its velocity.

Answer:
D. DNA
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
Deoxyribonucleic acid (DNA) is a strand of evidence which helped to provide a link in the evolution of whales from land mammals on 4 legs to a sea mammal with fins.
Basically, deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.
