supplement. Most car styling is based on presumed customer appeal. Apart from cars intended for really high speed. It is so easy to have a bigger power plant.
And, notoriously enough, most tyre patterns are similarly based, though special purpose tyres may have a proper design basis.

What happens to ca2 react to CO2?
There is no such molecule as Ca2. Calcium is simply Ca.

2Ca + CO2 --> 2CaO + C.
What is independent variable of what kills bacteria?
An independent variable is what you control. So in this case the independent variable would be how you're killing the bacteria (different solutions of bleach, different temperatures, different wavelengths of light, etc). The dependent variable is the variable you are looking for a change in, in this case it would be how many bacteria die.

Does soapstone absorb liquids?

What are real life applications of encoder and decoder?
Decoding is necessary in applications such as data multiplexing, 7 segment display and memory address decoding.
Generally, the boiling point of a liquid increases if the intermolecular force, i.e. pressure, increases.
Why thin cardboard is preffered in lee's disc experiment?
The cardboard having large cross sectional area and very small edge are is to be used so that very less heat is lost through the sides of the insulator.(accurate measurements)
