Which of the following oxides produces $H_2O_2$ when treated with $HCl$?

If $f(x) = x^3 - 10x^2 + 200x - 10$,then

The circuit shown contains a $12 \, V$ battery,a $4 \, \Omega$ resistor,and two branches in parallel,each containing an ideal diode and a resistor. Branch $1$ has diode $D_1$ and a $3 \, \Omega$ resistor,while branch $2$ has diode $D_2$ and a $2 \, \Omega$ resistor. Determine the total current flowing in the circuit. (in $, A$)

Among the following,the molecule with the highest dipole moment is:

The image of the point $(4, -13)$ with respect to the line $5x + y + 6 = 0$ is

In the given circuit, the current flowing through it is: (in $ A$)
