increase Definition and 865 Threads

In Demography, the rate of natural increase (RNI), also known as natural population change, is defined as the birth rate minus the death rate of a particular population, over a particular time period. It is typically expressed either as a number per 1,000 individuals in the population or as a percentage. RNI can be either positive or negative. It contrasts to total population change by ignoring net migration.
This RNI gives demographers an insight into how a region's population is evolving, and these analyses can inform government attempts to shape RNI.

    Temp increase of sun from photosphere to corona

    The photosphere is 4500 K The chromosphere is 10000 K The corona is 1,000,000 K The temperature increases as the distance from the core increases. This makes no sense to me. Any ideas? Thanks Nautica

    Bicycle spoke tension increase?

    Hello, Typical bicycle wheels have 36 spokes that are trued to a final tension of roughly 200 pounds. If a pair of adjacent spokes are squeezed together with one hand with a force of roughly 100 pounds, what does the spoke tension rise to? I'm asking because this healthy-squeeze...

    Can Black Holes Increase Their Mass According to Remote Observers?

    A remote observer describes a black hole with Schwarzschild coordinates. These have a coordinate singularity at the horizon, which implies that the distante between any spacetime point and the horizon is infinite. My question is whether a remote observer is allowed to claim that a black hole may...

    Understanding the Impact of Angular Velocity on Mass in Rotating Objects

    Hi, I know that a moving object has a greater mass due to relativistic effects. This may be a stupid question, but will a rotating or spinning object's mass increase as its angular velocity increases? Thank you for any help.

    Does Faster Speed Increase Mass?

    People say that the faster something moves the more mass it gains. I remember someone else saying that it doesn't gain actual mass, and explained it a different way. I can't remember what they said though. Anyone know what I am talking about or know if there is any truth to it? Is saying that...

    Does the entropy of a closed system always increase

    Question: Does the entropy of a closed system always increase, or could it possibly decrease? Answer: The standard answer to your question from the laws of thermodynamics is that entropy (disorder) will increase, but there are at least two ways I believe entropy can decrease in a closed...

    If a body is heated its gravity will increase

    it is my understanding that if a body is heated its gravity will increase, also if a body is given mommentum its gravity will increase. as both heat and mommentum are energy,there must be a formula to convert energy into strength of gravity, if correct, how would the orbital hight of a...

    Is it possible to increase the speed of light? (transmissions)

    I'm new here, and I am working on a script for the screen. What I have now is a man who the audience believes to be in space, but he is really isolated on earth. Now anyway, suppose an infant was put to sleep for 20 years, thus alienating dependence on parents or other role models. The...

    Does resonance increase in velocity

    Does increase in velocity and/or mass increase the effect on an atom's resonance? I was thinking maybe the faster an atom travels in one direction the slower the atom would vibrate. Any thoughts on this matter?
