It is an approximate average value for acceleration due to gravity on the surface of the earth. It is affected by altitude, the density of the material near the surface from place to place. And of course, it is totally useless in space, on the moon or Mars.
Well, isn't that a happy little question! A non-example of a constant of proportionality would be a relationship where the ratio between two quantities is not always the same. Imagine a situation where the more you paint, the less paint you use each time - that would not have a constant of proportionality. Just like in painting, it's all about finding balance and harmony in the relationships around us.
A rubber band will , approximately, stretch an amount "x" in direct proportion to the force "F" applied to it. So you can write this as an equation, F = KX . To find the proportionality constant "K" , hang a known weight "W" from the rubber band and measure the stretch "L". then divide W/L = K . This is called "calibrating" the rubber band.
The average weight of a seventeen year old varies greatly with gender and height, and those two elements are crucial in determining the average weight.
no it does not remain contant.
Mass is a property of matter and is therefore a constant. Weight however can change, it is the force exerted by that mass in a gravity field. Thus in different gravity fields a constant mass will weigh differently. Weight = Mass * the acceleration of gravity.

Constant immersion hydrometers are designed to be fully submerged in the liquid being tested, providing readings based on the buoyancy principle. Constant weight hydrometers are initially weighed in air and then in the liquid, with the difference in weight determining the liquid density. Constant immersion hydrometers are typically more accurate for measuring specific gravity, while constant weight hydrometers can be more convenient for quick measurements.
I don't think there is a weight restriction, because some ponies may be overweight, but in order to be classified as a pony, a Horse must be 14.2 hands or under when fully matured.
There is no weight restriction on the driver. There is a minimum weight for the car which is 3450 pounds.
The effect of gravity is measured.
That assumes gravity doesn't change. To say that two quantities, "a" and "b", are proportional means that you can write an equation: b = ka (for some constant "k"). In the case of weight: weight = mass x gravity In this case, "gravity" is the constant. That means that for different objects, the weight / mass ratio is always the same. Close to Earth's surface, this constant of proportionality - the gravity - is approximately 9.8 newton/kilogram. If you go far away from Earth, perhaps onto the surface of other planets, gravity is NOT constant, and the statement that "mass and weight are proportional" is not true.
Determining the weight of something.
Weight = Mass x (Local Gravitational Constant)/(Standard Gravitational COnstant)
Weight in a constant gravitational field is also constant, regardless of any surroundings. The weight will be two newtons underwater as well.
Yes, as long as it does not exceed the weight restriction.
proportionality
Constant weight is important in scientific experiments to ensure that any change in measurements or observations is due to the variables being tested and not due to changes in weight. Maintaining a constant weight helps to minimize potential sources of error and increases the accuracy and reliability of the experimental results.
