New Concepts/Shortcuts 3 Flashcards
shortcut for acceleration, friction exerted, and KE of a rolling object
and what’s the work done friction!?
how to approach this q!?
the total energy would be constant here
so find the total energy due to spring. rotational, translation, etc and then differentiate it with respect to t
then we would have an expression with respect to alpha and stuff where we can find the angular frequency expression
Trick for rotational pulley problems(finding alpha)
polytropic process formula for work done, molar heat capacity, heat exchange
what to do if we have a algebra+trigo equation and we have to find the number of solutoin
draw the graph of trigo and algebra part and find intersection points
expansion
damped equation formula from cos formulae
and also the angular frequency formula in a damped oscillation
potential gradient formula
where Ro is the resistance of the 1 m wire
and R1 is the internal resistance of the main Emf battery(not the one we have to find(
what if we have a number whose remainder is something other than 1
repeat the process till we have a 1 as a remainder
what forms a poorly soluble precipitate with reaction with Ph-SO2Cl
primary and secondary amine forms poorly soluble ppt wit h reaction with R-SO2Cl
Let A₁, A₂, …, An, n arithmetic means are inserted between two numbers ‘a’ and ‘b’ such that a, A₁, A₂, …, An, b from an AP.
write the formula for Ar
do we use end correction in the resonance tube?
only if we have to find the length of resonance
but if we have to find velocity, it isnt counted as the end correction gets subtracted in l2-l1
What’s the unit of planks constant?
Js
at t=inf P.D across inductor=?
0
benzene with an excess of Cl2 in the presence of AlCl3 forms?
friedal craft reactin doesnt happens with___-
partial double bond character
nu of photons/spectral lines if we have the ending and starting orbit number
which series lies in visible,IR and UV region
time taken for photocurrent is in the order
10^ -9
gunmetal consists of
Cu, Sn,Zn
epoxides in the acid medium have which kind of reaction and what if it’s in basic medium!?
What’s the perfect condition with respect to the magnetic susceptibility for a diamagnetic material?
magnetic susceptibility = -1 for a diamagnetic material
curie’s temperature formula for ferromagnetic and paramagnetic material
