Answer: A scenario often presented to introductory physics classes is that of a "gravity tunnel" — a tube drilled from one side of the Earth to the other through the planet's center. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds.
Explanation: However, solar and lunar gravity, which also perturb orbiting satellites, would eventually pull you into the tunnel wall anyway [source: Darling ]. Strike a chord: Fun fact: A straight line from any point to any other point through the planet would take the same amount of time to fall through like a tunnel through Earth's center.
Answer:
The correct answer would be Atria push blood into the ventricles and Ventricles push blood out of the heart.
In humans, four chambered heart is present with two atria and two ventricles.
Deoxygenated blood from all over the body is passed into the right atrium through vena cava (superior and inferior).
Simultaneously, oxygenated blood from the lungs is passed into the left atrium of the heart with the help of pulmonary vein.
Both the atria contract at the same time to drain their blood into respective ventricles.
The ventricles undergo relaxation while receiving blood.
The valves present between the atria and ventricles (tricuspid and bicuspid valve) ensures that the blood flows in one way direction only. They shut down as the ventricles contract and produce the sound "lub".
The ventricles contract simultaneously to pump blood out of the heart. The right ventricle pumps deoxygenated blood into pulmonary artery which takes the blood to the lungs for oxygenation.
The left ventricle passes the oxygenated blood through aorta to all the parts of the body.
The pulmonary and aortic valves prevent the back flow of blood and shut at the same time which creates second sound called as "dub".
Answer:
The hare population would most likely undergo logistic growth.
Explanation:
If conditions for them improved, the hare population would undergo an exponential growth. Then the lynx population would rise to match the exponentially growing numbers of hare. They would eat more hare and populations would stabilize at carry capacity limit.
Their populations fluctuate, one after the other, in a predictable way: when the snowshoe hare population increases, the lynx population tends to rise.
Answer:
Heat and/or pressure
Explanation:
This is because it is a direct path, rather than having to go through multiple processes. Hope I could help!
Answer:
Functionalism
Explanation:
Functionalism is the theoretical perspective in sociology, posits that for stability and social order to be established in a society, all social institutions that make up the society, must work interdependently to contribute to the functionality of the society. Social institutions in a society include, the government, family, economy, religion, media,education.
For example, for most societies that seem relatively stable, the family pay taxes to the government, the government as an institution rely on these taxes to provide education for the children of the family in that society. All parts of this society are interdependently inherently connected.
