Men did actually walk on the moon.
Incompetent mitral valve allows the retrograde flow of blood from the left ventricle into the left atrium.
If the flow tube radius on the left is increased, the flow rate will increase because a larger cross-sectional area allows for more fluid to pass through. Conversely, if the flow tube radius on the left is decreased, the flow rate will decrease as the smaller cross-sectional area restricts the flow of fluid. The flow rate is directly proportional to the radius of the flow tube.
No. The Apollo astronauts left instruments to measure the temperature deep below the surface of the moon. All readings indicate a cold moon. The Apollo 17 astronauts found volcanic material, indicating that the moon was hot when it formed, but quickly cooled.
Because heat transfers to colder objects, and the bottle left out in the sun is exposed to a lot more heat than the one in the refrigerator.
Scientists can often find clues about past eruptions by studying the deposits left behind. Areas affected by lava flows, debris flows, tephra, or pyroclastic flows can be mapped, making disaster planning more effective. In addition to this type of long-range forecasting, scientists are becoming more and more skilled at spotting the warning signs of an eruption.
Heat always, and only, flows from a hot item to a cooler one.
The process of plastics becoming brittle after being left in the sun is typically an exothermic reaction. The heat from the sun causes the molecules in the plastic to break down, leading to a change in its physical properties.
It'll flow either right to left... or left to right; Depending on which side of the river you are standing.

Heat is a form of energy, that energy would flow from a high concentration to a low concentration, i.e. from the warmer system to the cooler system until they reach thermal equilibreum. Research the Zeroth law of thermodynamics
Roy Orbison did everything left-handed except play instruments, according to an interview he did.
Basically the same that happens to heat energy left anywhere else. It can stay warm for a while, but eventually, the heat will dissipate.
Conventional current is defined as the flow of positive charges. If the actual flow is negative particles (as is often the case; usually electrons), the conventional current flows in the direction opposite to the electron flow.
