How are vibrations different between bigger sizes rubber bands and smaller sized rubber bands?

Answers

Assuming the kind of vibration you are talking about is the kind where you stretch the rubber band between two points and then "twang" it, then the answer is fairly complex. What happens when you cause the vibrations to start is you make something called a "standing wave". In a standing wave, each particle in the rubber band has a certain amount of energy which causes it to move backwards and forwards, the particles with more energy have a larger "amplitude" (how much they move), and of course the particles with less energy have a smaller amplitude. Now a standing wave has two main components: The amplitude, and the frequency. The amplitude of the whole wave refers to the largest amplitude any particles has. The frequency refers to how often it takes for one of the particles to move between the two furthest away points it can be.
To compare rubber bands, you must remember to keep certain things constant. If you're looking at their vibrations, the amount of energy you use to "twang" the rubber band should be the same each time you twang it (which is the same as applying the same force each time you twang it).

A larger rubber band has more area over which to spread the energy, as well as it has more mass for the energy to move, so the vibrations will have smaller amplitudes, and smaller frequencies, overall vibrating less and with smaller vibrations.

What is the chemical equation for the burning of propane if all the products and reactants are in the gas phase?4H2O(g) + 3CO2(g) + 5O2(g) → C3H8(g)

C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)

C3H8(g) + O10(g) → 3CO2(g) + 4H2O(l)

4H2O(l) + 3CO2(g) → C3H8(g) + 5O2(g)

Answer - B -
C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)

Answers

Propane is a hydrocarbon and it will burn in presence of oxygen (it will undergo combustion) to give carbon dioxide and water (all in gas phase).

In presence of oxygen the carbon gets oxidized to carbon dioxide and hydrogen to water.

The general equation for a hydrocarbon undergoing combustion is

$CxHy(g) + (x+(y)/(4))O_(2) ---> xCO_(2)(g) +(y)/(2)H_(2)O(g)$

Here we are studying the combustion of propane so

x = 3

y = 8

Propane has molecular formula of C3H8

Therefore the balanced equation will be

$C3H8(g) + (3+(8)/(4))O_(2) ---> 3CO_(2)(g) +(8)/(2)H_(2)O(g)$

$C3H8(g) + 5O_(2) (g) ---> 3CO_(2)(g) + 4H_(2)O(g)$

How long is a red blood cell

Answers

I suspect this question should read "How long does a red blood cell live." A red blood cell lives for between 100 and 120 days. It takes 7 days for a new red blood cell to develop from stem cells. Stem cells are similar to base cells. They can also be seen as a general template from which specialized cells are made. Stem cells can be taken from a newborn baby's umbilical chord or extracted from an adult blood donor's blood.This
