Inelastic collision happens when two objects joined and move together after the collision
The correct answer is silver metal.
Conductivity measures the ability of a material or a metal to transmit energy, conductivity may be electrical, thermal or acoustical conductivity. The most electrical conductive element is silver, followed by copper and Gold. Silver also has the highest thermal conductivity as compare to any element. However, copper and Gold are more often used in electrical applications since copper is less expensive and gold has a much higher corrosion resistance.
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,

or
n = 8345714 cell membranes
Answer:
1/9 E
Explanation:
The electric field produced by a charged sphere outside the sphere is equal to that produced by a single point charge:

where
k is the Coulomb's constant
Q is the charge on the sphere
r is the distance from the centre of the sphere
In this problem, we have a sphere of radius R (smaller sphere) with a charge Q that produces an electric field of magnitude E at r=R.
For the larger sphere,
R' = 3R
Therefore, the electric field at r=R' will be

So, the electric field just outside the larger sphere will be 1/9 E.
