coordination compounds

a,b,c options are correct and none are clear to me.. a- why is it paramagnetic if all electrons are paired b- is this correct reason? bond order of super oxide is 1.5 and neutral Oxygen molecule is 2, so bond length is more c- how are we supposed to know if O2 here is superoxide or peroxide ligand, bcuz the oxidation state of Fe will also change according to that...

Capacitor or EMW doubt

Consider a capacitor with UV light ionizing $n_{0}$ electrons per unit volume per unit second. Now each electron moves towards a plate. Given that plate 2 is at a higher potential than 1, and each electron moving ionizes $\alpha$ more electrons per unit length of the path find the number of electrons as a function of x and current density in the two plates.

rotational

A disc of mass m radius r is given a velocity v and angular velocity w and released on a horizontal surface with coeff of friction u. It is given that v=rw/4 and w is opposite to v then find time at which pure rolling starts.

can h2co3 and k2co3 form a buffer? if yes then is it possible for 1L 1N naoh to form buffer with 0.75M 1L h2co3 or 0.65M 1L h2co3 to form a buffer ?...

Electricity Class 10

Please give a detailed solution of this question. I asked a friend but he told me to study Kirchhoff's Law. I watched a lecture online and am clear with it, but I am not sure how the current will be distributed here or what resistors will be ignored.

Definite Integration Doubt

Consider the function f(x)=$\int_{0}^{x}{(x-t)^{2}g(t)}dt$ Given the value of g(1) and integral of g(x) from x=0 to 1, we are supposed to f''(x)-f'''(x)

CHEM BONDING

Relation between backbonding and acidic strength? - in the first example, backbonding in sih3oh is the reason for it to be more acidic. - but the second example also makes sense. here when the back bonding is effective, the shortage of electrons is compensated and the lewis acid character decreases....
