V square - u square = 2as. here s=distance
here v squared= 18 squared=324
u squared=12 squared=144
324-144=2×36×s
180=72s
hence distance=2.5

Answer:

I was going to give you the paper where I saw it but since you are not giving enough points I can not give you so I am only going to give you some of these that are here sorry

Explanation:

1.

$9^{2} + 12^2 = x^2\\81 + 144= x^2\\\sqrt{225} = \sqrt{x} \\ 15=x\\\\ 2.\\x^2+12^2+=13^2\\x^2+144 =169\\x^2 = 25\\\sqrt{x^2 =\sqrt{25\\\\$

x=5

$3.\\12^2+32^2 = x^2\\34.176= x$

7.

5,12,13

9.

$\frac{x}{4} ,\frac{12}{4} ,\frac{20}{4}\\\\\frac{x}{4},3,5 \\\\x=16\\\\12. \\x^2 + 48^2=50^2\\\\x^2=196\\x=14$

Why will a sheet of paper fall slower than one that is crumbled into a ball

Zarrin [17]

It’s coming in contact with more air molecules than I would if it was in a ball because there is less surface area
