Answer: The angle of refraction is 32°
Explanation:
By snell law, we have that:
n₁*sen(θ₁) = n₂*sen(θ₂)
Where n₁ = 1.5
n₂ = 2.0
θ₁ = 45°.
then we want to find the angle of refraction.
1.5*sin(45°) = 2*sin(x)
x = Asin(1.5*sin(45°)/2) = 32°
When water molecules
diffuse through a cell membrane this process is called the osmosis. Water
molecules are extremely small and because of this they can slip freely through
the gaps between the phospholipids in the cell membrane. And as a result, water
molecules can constantly move back and forth though the cell <span>
membrane. This movement of water has a very important
function and that is it enables cells to absorb water. </span>
Now for a movement of
water molecules to happen, there should be a concentration gradient in the surrounding.
That is, the amount of water in one side must be different on the other side.
<span>For water to diffuse
INTO the cell, the amount of water outside the cell membrane should be larger
than the amount of water inside the side.</span>
ANSWER:
THE THREE LAW OF MOTIONS ARE LAW OF INERTIA, LAW OF INTERACTION & LAWW OF MASS AND ACCELERATION
- Law of Inertia - An object at rest and an object in motion stays in motion with the same speed and in the same direction.
- Law of Interaction - For every action, there is an equal but opposite reaction.
- Law of Mass and Acceleration - The acceleration of an object as produced by a net force is directly to the magnitude of the net force and inversely propotional to the mass of the object.
<em>F= ma ; a=F/m</em>
<em />
wherein;
<em>F= Force (N)</em>
<em>m= mass (kg)</em>
<em>a= acceleration (m/s^2)</em>
