<span>The correct option is A. There are three basic type of solutions, these are: unsaturated, saturated and super saturated solution. An unsaturated solution is a solution that has the capacity to hold more solute at a particular temprature, it is a solutin that is not yet saturated with the solute [particles dissolve in it].</span>
Answer:
A = L^3 T^-3 , B = L^3 T
Explanation:
Given: volume ( V ) = At^3 + B/t ------ ( 1 )
dimension of volume = L^3
and the Dimension of time = T
back to equation ( 1 )
L^3 = A * T^3 ------- ( 2 )
also L^3 = B/T ------- ( 3 )
from equation ( 2 )
A = L^3 T^-3
from equation ( 3 )
B = L^3 T
<u>The dimensions of the constants A and B </u>
A = L^3 T^-3 , B = L^3 T
Coulomb's law states<span> that: The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the scalar multiplication of the magnitudes of charges and inversely proportional to the square of the distance between them.

Answer:
F = - 2 A x - B
Explanation:
The force and potential energy are related by the expression
F = - dU / dx i ^ -dU / dy j ^ - dU / dz k ^
Where i ^, j ^, k ^ are the unit vectors on the x and z axis
The potential they give us is
U (x) = A x² + B x + C
Let's calculate the derivatives
dU / dx = A 2x + B + 0
The other derivatives are zero because the potential does not depend on these variables.
Let's calculate the strength
F = - 2 A x - B
Years of research have demonstrated that rats are intelligent creatures who experience pain and pleasure, care about one another, are able to read the emotions of others, and would assist other rats, even at their own expense.
<h3>Experiments:</h3>
In trials carried out at Brown University in the 1950s, rats were trained to press a lever for food, but they stopped pressing the lever when they noticed that with each press, a rat in an adjacent cage would scream in pain (after experiencing an electric shock).
Rats were trained to press a lever to lower a block that was hanging from a hoist by electric shocks administered by experimenters. A rat was subsequently hoisted into a harness by the experimenters, and according to their notes, "This animal normally shrieked and wriggled sufficiently while dangling, and if it did not, it was jabbed with a sharp pencil until it exhibited indications of discomfort." Even if it wasn't in danger of receiving a shock, a rat watching the scenario from the floor would pull a lever to lower the hapless rodent to safety.
