Answer:
C
Explanation:
Alveoli are tiny functioning structures that compose your lungs. They help with respiration. They have a large total surface area, which is very useful for respiration. The more surface area there is, the more transactions can happen. Which means that breathing will be easier/faster when you have more alveoli. (Please rate this answer if you have time!)
Answer: Friction is like when u take two stick's and rub it together to make fire when you use friction it can produce heat. Applied force is like and applied to an object or person if a person is pushing a desk across the room then there is applied force.
Answer:
The Moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis.
Answer:
Verdadera.
Explanation:
La caloría se puede definir como una unidad estándar utilizada para medir la cantidad de energía presente en un organismo vivo.
Una caloría (cal) es la cantidad de transferencia de energía necesaria para elevar la temperatura de 1 g de agua de 14,5 °C a 15,5 °C.
Generalmente, es una unidad de medida de energía e igual a 4,1855 julios.
Width of the fringes gets decreased if the distance between the slits is increased and thus we get narrower fringes.
What is Young's double-slit experiment?
- In modern physics, the double-slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles; moreover, it displays the fundamentally probabilistic nature of quantum mechanical phenomena.
- This type of experiment was first performed, using light, by Thomas Young in 1802, as a demonstration of the wave behavior of light.
- A wave is split into two separate waves (the wave is typically made of many photons and better referred to as a wave front (not to be confused with the wave properties of the individual photon)) that later combine into a single wave.
- Changes in the path-lengths of both waves result in a phase shift, creating an interference pattern.
- A coherent light source, such as a laser beam, illuminates a plate pierced by two parallel slits, and the light passing through the slits is observed on a screen behind the plate.
- The wave nature of light causes the light waves passing through the two slits to interfere, producing bright and dark bands on the screen – a result that would not be expected if light consisted of classical particles. However, the light is always found to be absorbed at the screen at discrete points, as individual particles (not waves); the interference pattern appears via the varying density of these particle hits on the screen.
- Furthermore, versions of the experiment that include detectors at the slits find that each detected photon passes through one slit (as would a classical particle), and not through both slits (as would a wave).
- However, such experiments demonstrate that particles do not form the interference pattern if one detects which slit they pass through. These results demonstrate the principle of wave-particle duality.
