Use your units !
"Period" is time . . . 12 seconds.
"Frequency" how often . . . " ___ PER time". Time is in the denominator.
"12 seconds per wave" means
1 wave / 12 seconds
= ( 1 / 12 ) (wave/second)
= 0.08333... wave per second
= 1/12 Hz.
Answer:
1. Both are respiratory organs found in vertebrates.
2. Both enable the inhalation of oxygen and exhalation of carbon dioxide in the bodies of their host.
3. Respiratory membranes present in both make the exchange of gases easier.
4. Blood vessels found around them enable the breathing process.
Explanation:
Gills are respiratory organs which can be found in animals that live in water. These include fishes, amphibians like frogs, anthropods like insects, and annelids like worms. Gills are surrounded by respiratory membranes known as gill lamellae which have a large surface area that makes breathing easier. Blood vessels also are found around gills.
The lung is also a respiratory organ found in humans. It runs from a windpipe known as the trachea and branches into bronchi which contain the bronchioles. Alveoli ducts contain alveoli sacs and then alveoli which are membranes that enable the breathing process.
Both are similar because they are respiratory organs found in animals with backbones. They are surrounded by blood vessels and membranes that make the breathing process easier.
Answer:
5:00p.m
She is traveling 30 miles and moves 10 miles for each hour therefore 30/10=3
This means she cycled for 3 hours adding this to our time we then have 5p.m
Based on the given displacement vs time graph, the object is at rest at a time interval of: B. 2 to 3 seconds
<h3>What is a
displacement vs time graph?</h3>
A displacement vs time graph can be defined as a type of graph that is used to graphically represent the distance traveled (covered) or displacement experienced by an object from its starting position with respect to the time when it has started moving.
In Science, a physical object being at rest simply means that the position of the object is not changing with respect to time. Thus, both the slope and velocity of the physical object would be equal to zero when it is at rest.
Between 0 to 2 seconds on the given displacement vs time graph (see attachment), this object is traveling at a constant, positive velocity. However, at a time interval of 2 to 3 seconds the object is at rest.

Answer:
Newton's first law of motion
Explanation:
Newton's first law of motion states that an object will continue to remain at rest or move with uniform motion unless it is acted upon by an external force.
This law is known as the law of inertial.
Unless a net force greater than zero acts on a body, it will continue to remain at rest or move uniformly.
This is very correct and has a wide range of application for many mechanics studies. In that we know that an object can only change motion or accelerate by adding external force to act on it.
