Find Natural Response of RLC Circuit: No Forcing Voltage?
To find the natural response of a RLC circuit driven by a time-varying voltage, why do we assume that there's no forcing voltage driving the circuit even if there is one?- <sHoRtFuSe>

Graduate Why are finite angles considered vectors if they don't follow vector addition?
If the physical quantity angle doesn't follow the vector addition property (only infinitesimal angles follow this), why is it even considered to be a vector? Because i thought electrical current isn't considered to be a vector because it doesn't follow this rule. Why isn't it enough to rule out...- <sHoRtFuSe>

Probability of Getting 4 Tails in 10 Flips
Let p=Probability of getting Heads=0.5 q=Probability of getting Tails=0.5 assuming all flips are independent, probability of getting 4 heads=p*p*p*p*q*q*q*q*q*q you are doing the mistake of assuming getting 1, 2, 3 ...heads(or tails) is equally likely. They clearly aren't. This is a...- <sHoRtFuSe>

Hard probability problem (1973 British Math Olympiad #6)
Let, E1:Student answers correctly. E2:Teacher answers correctly. E3:Student is a boy. **Not assuming any of these events are independent** P(E2)=A...(a) P(E1/E3)=B ∴P(E1∩E3)/P(E3)=B ∴P(E1∩E3)=B×P(E3)...(b) Also, P(E1/E3bar)=G [E3bar is negation of E3] ∴{P(E1)-P(E1∩E3)}/1-P(E3)=G substituting...- <sHoRtFuSe>

Undergrad Making sense of the units of entropy: J/K
Entropy is the measure of randomness right? Heat is a form of energy that kind of shows how random a system is. Hence there is the SI unit of heat in the numerator as more of it icreases randomness. As for the K in the denominator, for a particular system and a given amount of heat, entropy...- <sHoRtFuSe>

Undergrad Is there a minimum velocity for continuous motion?
Yeah i think this is the reason for zero-point energy. Each particle will have that minimum energy, and hence, a minimum velocity.- <sHoRtFuSe>
