 <span>Cells undergo mitosis for three main reasons: 
-To repair and/or replace old or damaged cells. 
-During periods of cell and tissue growth 
-When the body needs exact replicas/copies of cells e.g. hair cells and blood cells.</span>

A certain metal with atomic mass 2.2 × 10−25 kg has an interatomic bond with length 2.3 × 10−10 m and stiffness 43 N/m. What is
Alexandra [31]

Answer:

The speed of sound in a rod made of the material is 3215.52 m/s.

Explanation:

The speed of sound can be found using the formula:  

V=\sqrt{\frac{s}{m}}*d

Where s is the stiffness, m the atomic mass and d is the length of the interatomic bond.  

You just have to correctly replace these values in the formula above.

V=\sqrt{\frac{43N/m}{2.2 * Exp-25 kg}}*(2.3 * Exp-10 m)

V= 3215.52 m/s

Calculate the electrostatic force that a small sphere A, possessing a net charge of 2.0 x 10^-6 Coulombs exerts on another small
Anni [7]

Answer:

F = 5.33*10^-4N

Explanation:

to find the electrostatic force you use the Coulomb's law, given by the formula:

F=k\frac{q_Aq_B}{r^2}

k: Coulomb's constant = 8.89*10^9 Nm^2/C^2

q_a: charge of A = 2.0*10^{-6}C

q_B: charge of B = -3.0*10^{-6}C

r: distance between the spheres = 10.0m

By replacing all these values you obtain:

F=(8.89*10^9Nm^2/C^2)\frac{(2.0*10^{-6}C)(-3.0*10^{-6}C)}{(10.0m)^2}=5.33*10^{-4}N

hence, the forcebetween the spheres is about 5.33*10^-4N
