A cell membrane has a thickness of about 7 nm. How many cell membranes would it take to make a stack 3.4 in high?
1 answer:
Answer:
486 of cell membranes
Explanation:
one cell membrane has 7*10^-9m as the height
So, by dividing 3.4 with 7*10^-9 you will get the number of cell require to form the height.
3.4/(7*10^-9)=485.71
because we can't have decimal number of cell we would round it into three significant figures, 486.

Momentum of an object = (its mass) x (its speed) .
Since speed is a factor of momentum, an object that
isn't moving doesn't have any.
-- The moving player has momentum.
-- The stationary one doesn't.
