A lever of class 1 has a lotal length of 3m and is able to lift a load of 60N with a force of 30N at a Time Find
the position of the fulcrum.​

Fin Lin = Fo Lo  Work = Work out where in = input and o = output

Fin / Fo = Lo / Lin = 30 / 60 = 1/2   (input force = 1/2 output force)

Lin + Lo = 3

Lo = 3 - Lin

1/2 = (3 - Lin) / Lin    from above

1/2 = 3 / Lin - 1

3 / Lin = 1.5   and Lin = 2

So the input length = 2 m and the output length = 1 m

the results is a decrease in air temperature with an increase of altitude.

explanation:

yo yo yo its papaguy in the house lol

okay, ima .

um it shows links to uh so kinda microsoft website is that were ima go or no? ?
