A bird is flying at 10 miles per hour east: Speed = 10 miles per hour, velocity = 10mph in eastward direction, Acceleration = 0 m/s².
What is speed, velocity and acceleration?Speed is the rate at which an object covers distance; Velocity is the rate at which an object changes its position in a particular direction and Acceleration is the rate at which an object changes its velocity over time.
(1) Speed = 10 miles per hour
Velocity = 10mph in eastward direction
Acceleration = 0 m/s²
(2) Speed = The car's speed when traveling at 50 miles per hour is 50 miles per hour. When the car slows down to 20 miles per hour, its speed becomes 20 miles per hour.
Velocity = initial velocity is 50 miles per hour in the direction of travel. When it slows down to 20 miles per hour, its velocity becomes 20 miles per hour in the same direction.
Acceleration = Acceleration = (20 miles per hour - 50 miles per hour) / 10 seconds
= -3 miles per hour per second
(3) Speed = 2 feet per second
Velocity = Cannot determine
Acceleration = Cannot determine
(4) The distance traveled in a given time is known as "displacement"
(5) Speed = 2 meters per second east.
Velocity = 2 meters per second north
Acceleration = zero
(6) Speed = 5 meters per minute.
Velocity = 5 meters per minute east
Acceleration = cannot determine
(7) Speed = 70 miles per hour
Velocity = 70 miles per hour (North)
Acceleration = cannot determine
(8) Speed = 1/3 miles per hour
Velocity = 1/3 miles per hour
Acceleration = 0 miles per hour per hour
(9) Speed = Cannot be determined
Velocity = Cannot be determined
Acceleration = Cannot be determined
(10) Speed = 3 meters per second
Velocity = 3 meters per second
Acceleration = 0 meters per second per second (since light always travels at a constant speed and does not accelerate)

Chromosomes, which are shaped like threads and house the DNA molecule in each cell, are found in the nucleus. The DNA that makes up each chromosome is tightly coiled around histone proteins several times to support its shape. Thus, option A is correct.
What are the important composition of nucleus?The chromosomes in the cell nucleus and mitochondria contain DNA (deoxyribonucleic acid), which is the genetic material of the cell.
With the exception of certain cells, every cell's nucleus contains 23 pairs of chromosomes (such as sperm and egg cells and red blood cells). One chromosome has a large number of genes.
DNA composition. The most of DNA is located in the nucleus of a cell, where it is organized into chromosomes. Chromosomes contain histone proteins, which attach to DNA. When two strands of DNA are twisted together, they take the shape of a helix.
Therefore, the Nucleus contains chromosomes, genes, and DNA.
