t1 = √2h1/g = √2*0.5/9,8 = 0.319 sec
t2 = √2h2/g = √2*1.0/9,8 = 0.451 sec

In which t = times for the vertical movement
h = height
g= gravity (we use standardized measurement of 9.8)

d1 = 1*0.319 = 0.319 m
d2 = 0.5*0.451 = 0.225 m

in which d = Horizontal distance

ratio
= di : d2
= 0.319 : 0.225

= 3.19 : 2.25

A cell membrane has a thickness of about 7 nm. How many cell membranes would it take to make a stack 2.3 in high?

Alisiya [41]

Answer:

There are 8345714 cell membranes.

Explanation:

It is given that,

The thickness of a cell membrane is 7 nm

We need to find the number of cell membranes would it take to make a stack 2.3 inches high.

Firstly, the units must be same i.e. converting 2.3 inches to m

1 inch = 0.0254 m

2.3 inches = 0.05842 m

Let there are n number of cell membranes. So,

$n=\dfrac{\text{stack height}}{\text{1 membrane thickness}}\\\\n=\dfrac{0.05842}{7\times 10^{-9}}\\\\n=8345714.28$

n = 8345714 cell membranes
