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.
Answer:
It's called the resultant
From looking at the two force equations, you can see the similarities and how gravitational force can be considered parallel to the force between two charges.
Besides being proportional to the inverse of the square of the separation: both forces extend to infinity,They also both travel at the speed of light.
