Which among the following is the strongest acid?

Which of the following is emitted when $^{239}_{94} Pu$ decays into $^{235}_{92}U$ ?

Consider a solenoid carrying current supplied by a DC source with a constant emf containing iron core inside it. When the core is pulled out of the solenoid, the change in current will

A bag contains $5$ red balls, $3$ black balls and $4$ white balls are drawn at random. The probability that they are not of same colour is

A parallel beam of light of intensity \(I_0\) is incident on a coated glass plate. If \(25\%\) of the incident light is reflected from the upper surface and \(50\%\) of light is reflected from the lower surface of the glass plate, the ratio of maximum to minimum intensity in the interference region of the reflected light is

A planet of mass $m$ moves in an elliptical orbit around an unknown star of mass $M$ such that its maximum and minimum distances from the star are equal to $r_1$ and $r_2$ respectively. The angular momentum of the planet relative to the centre of the star is

The bond length (pm) of $ {F_2, H_2, Cl_2}$ and $ {I_2}$, respectively is

An electron collides with a Hydrogen atom in its ground state and excites it to $n = 3$ state. The energy given to the Hydrogen atom in this inelastic collision (neglecting the recoil of Hydrogen atom) is

If $\frac{x^{2} + 5}{\left(x^{2} + 1 \right)\left(x-2\right)} = \frac{A}{x-2} + \frac{Bx+C}{x^{2} + 1 } , $ then $A + B + C = $

A thermocol box has a total wall area (including the lid) of $1.0 m ^{2}$ and wall thickness of $3 cm$. It is filled with ice at $0^{\circ} C$. If the average temperature outside the box is $30^{\circ} C$ throughout the day, the amount of ice that melts in one day is [Use $K_{\text {thermocol }}=0.03 W / mK$ $.L_{\text {fusion (ice) }}=3.00 \times 10^{5} J / kg ]$

Consider the single electrode process $4H^{+} + 4^{-} e 2H _2$ catalyzed by platinum black electrode in $HCl$ electrolyte. The potential of the electrode is $-0.059\,V$ $V. SHE$. What is the concentration of the acid in the hydrogen half cell if the $H_2$ pressure is $1$ bar ?
