Why do patients with pheochromocytoma have facial pallor?
cathecolamines producing vasoconstriction, causing pallor.
Where is the thermal energy coming from causing dry ice to sublimate?
It's the same principle as if a liquid is evaporating, for example. It requires thermal energy to evaporate the liquid, or to sublimate a solid; therefore, this process will cool down (in this example) the dry ice, and the surrounding air.
What is a weakening of connective tissue in older patients?
There is a variety of causes. One cause is the reduction of the amount of collagen present causing a loss of elasticity in diverse tissues. Some level of dehydration is also common in older patients causing loss of tone and adherence.
What principle is it when a brick doesn't float on water?
The principle is called buoyancy or Archimedes' principle. The brick sinks in water because its density is greater than that of water, causing it to displace less water than its own weight. This results in a net downward force greater than the buoyant force acting upwards, causing the brick to sink.
Is floating in salt water an example of bernoulli's principle?
No, floating in salt water is not an example of Bernoulli's principle. Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases. Floating in salt water is due to the principle of buoyancy, where an object displaces an amount of water equal to its weight, causing it to float.
What is the principle used in constructing a liquid thermometer?
The principle behind a liquid thermometer is thermal expansion. As the temperature increases, the liquid inside the thermometer expands, causing it to rise in the narrow tube, giving a reading of the temperature.
How does Bernoulli's principle affect the trajectory of a curveball in baseball?
Bernoulli's principle affects the trajectory of a curveball in baseball by creating a pressure difference on the ball's surface, causing it to curve due to the Magnus effect.
What is true of upwelling?
It is driven by temperature differences causing differences in density. It requires a gravity field.
What is 52-50 for psychiatric patients?
If I'm not mistaken, 52-50 means that the individual is at risk of causing harm to themselves or others.
What is principal-agent problem?
In politics, the principle is the citizen, who poses the right to make certain decisions. The agent is members of Congress. The problem is when the principle and agent have different goals, causing conflict to arise. One might feel their Congressman is "out of touch" or not getting things done.
What operating principle of float-type carburetors is based on?
increase in air velocity in the throat of a venturi causing an increase in air pressure.
Which principle explains why the flame bends toward the wind?
The Bernoulli's principle explains why a flame bends towards the wind. As the wind blows over the flame, it creates a lower pressure area above the flame than below, causing the flame to bend in the direction of the wind to equalize the pressure difference.
