Good luck to all of you!!!!
Believe in yourself!!!

angles will be 36, 54,90
hence required ratio will be sin90/sin36

Let me make my question clear
In designing a project, I was having two circuits c1 and c2
if i will combine them in thew form of c3, will there be any change???
see the circuit elements:resistors.
in both the cases, the potential across any resistor is same, then what is difference as long as circuit elements are concerned, because practically you are concerned only with them.

157,114 etc.
take any multiple of 57, "add" any digit to its leftmost place

wow, you are right

i can't understand your (c) option
rest a,b,d are correct.
explanation
normal force and frictional force are always perpendicular.
let them be the sides of a rectangle.
now contact force is diagonal of this rectangle.
you can see that a,b and d easily follow

organic chem
it requires much more imagination
algebra or geometry

consider circuit 1
battery of potentialV, resistanceR, current I=V/R will be flowing through resistor
circuit2
battery of potentialV, resistance r, current i=V/r will be flowing through resistor
circuit3
battery of potentialV, resistanceR and reaistance r connected in parallel, current I=V/R will be flowing through resistor R,current i=V/r will be flowing through resistor r
Is the circuit 3 is equivalent to circuit 1 and circuit 2?

make a triangle for the given equation

ques6
Sk is a gp with common ratio less than 1
hence Sk=1/{1-1/(k+1)}
Sk=(k+1)/k
k*Sk=k+1
hence the answer is sum of first n+1 natural numbers -1
=(n+1)(n+2)/2 - 1
|
|
|
|
let the sum you have to find be S
subtract S from the gives series, take 1/4 common out of it
hence
pi^2/6 - S= pi^2/24
S=pi^2/8
