the power of a lens used in a spectacle is -3.5 diobter what is the focal length and nature of the lens |
|
Answer» ong>ANSWER: Evaporation is the process in which a liquid state of matter (water) is converted into a GASEOUS state of matter (vapour). In GENERAL terms, evaporation is defined as the process in which the liquid state is converted into gas. This process requires heat energy. Examples of Evaporation Crystallization Drying of clothes Factors That Affect the Evaporation Temperature: As the temperature increases, the rate of evaporation also increases. Temperature and rate of evaporation are PROPORTIONAL to each other. Surface area: As the surface area increases, the rate of evaporation increases. The surface area and rate of evaporation are proportional to each other. Humidity: The rate of evaporation decreases with an increase in humidity. Humidity and the rate of evaporation are inversely proportional to each other. Wind SPEED: Increase in wind speed results in increased evaporation. Wind speed and rate of evaporation are proportional to each other. |

Explain near point and far point of a human eyes. |
|
Answer» ong>Answer: Near point Of Eye;In visual perception, the near point is the closest point at which an OBJECT can be placed and STILL form a focused image on the retina, within the eye's accommodation range. The other limit to the eye's accommodation range is the far point. A normal eye is considered to have a near point at about 11 cm (4.3 in) for a thirty year old. The near point is highly age dependent (see accommodation). A PERSON with hyperopia or presbyopia WOULD have a near point that is farther than normal. Sometimes, near point is given in diopters (see Presbyopia § Mechanism), which refers to the inverse of the distance.Far Point of Eye;in visual perception, the far point is the farthest point at which an object can be placed (ALONG the optical axis of the eye) for its image to be focused on the retina within the eye's accommodation. It is sometimes described as the farthest point from the eye at which images are clear. |

Is the internal energy of an ideal gas a function of pressure? Explain |
|
Answer» ong>Answer: The internal ENERGY of a system can be UNDERSTOOD by examining the simplest possible system: an ideal gas. Because the particles in an ideal gas do not interact, this system has no potential energy. The internal energy of an ideal gas is therefore the sum of the kinetic energies of the particles in the gas Explanation: THANK you.... |
