|
After X half-lives, what fraction of the initial amount of radioactive material will remain?
|
(2)^(-X)
|
|
|
What value corresponds to the area under a F vs t graph?
|
Impulse (= F*t)
|
|
|
What is the speed of light in m/s?
|
3 * (10^8)
|
|
|
Express Joules in SI units...
|
J = N * m = kg * (m^2) * (s^ -2)
|
|
|
How is Ksp related to a saturated solution?
|
Ksp = the solubility product constant = the equilibrium constant for solvation. Consider that a saturated solution is in the equilibrium of solvation (solute is precipitating out as quickly as it is dissolving).
|
|
|
Define: amphipathic
|
Both hydrophilic and hydrophobic (e.g. a phospholipid)
|
|
|
Define: amphoteric
|
Able to act as an acid and as a base (e.g. water)
|
|
|
What is the relationship between the voltages, current, resistances, and capacitances of resistors in series?
|
V(tot) = V(1) + V(2)
I(tot) = I(1) = I(2) R(tot) = R(1) + R(2) (inverse)C(tot) = (inverse)C(1) + (inverse)C(2) |
|
|
What is the relationship between the voltages, currents, resistances, and capacitances of resistors in parallel?
|
V(tot) = V(1) = V(2)
I(tot) = I(1) + I(2) (inverse)R(tot) = (inverse)R(1) + (inverse)R(2) C(tot) = C(1) + C(2) |
|
|
In the context of approximations of ideality of gases, what does V(real) correspond to?
|
The volume of space BETWEEN molecules. This is why V(ideal) would assume point masses as molecules.
|
|
|
In a given collision in a closed system (such that no external forces are considered), is momentum always conserved? Kinetic energy?
|
Momentum is always conserved in a collision, but kinetic energy is only conserved in an elastic collision.
|
|
|
Define: Perfectly inelastic collision
|
A collision in which momentum is conserved, but kinetic energy is not conserved, and in which the objects stick together after colliding.
|
|
|
Which sort of collisions result in the largest change in kinetic energy of the system?
|
Perfectly inelastic collisions
