If you see a snake the best thing to do is walk away if it’s chasing you DO NOT RUN this might seem crazy but let it go on you and just Stand there the snake will think your just a plain standing pole do not touch it before it will hurt you add me and thank me for more PS:If you have questions for me just put it in the comments and I’ll answer them but if you want to see them you have to add me

So, is this just a 'just you should know' thing?

Step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
