Explanation

A conjunction p ∧ q (p AND q) is true only when both p and q are true.

Explanation

The symbol ∼p means "not p".

If ∼p is true, then p must be false.

Explanation

 A PN junction diode allows current to flow only in one direction — from P to N (forward bias).

During the positive half cycle of AC, the diode is forward-biased (low resistance), so current flows.

During the negative half cycle, the diode is reverse biased, so it blocks current and offers high resistance.

Explanation

 Leaving group ability:

A good leaving group is a species that can easily depart from a molecule taking a pair of electrons with it. 

Halide trend:

Among halogens (I, Br, Cl, F), iodide (I-) is the best-leaving group because it is the weakest base, meaning it is most stable with a negative charge.

If matrix A has an order of 3x4, then its transpose, denoted as AT, will have an order of 4x3

Explanation

Let the two charges be:

• $+q$ at one end

• $-q$ at the other end

• Distance between them = $2d$

• Midpoint = distance $d$ from both charges

The electric potential at a point due to a charge:

V= kq/r​

So, at the midpoint:

• Potential due to $+q$: +kq/ d​

• Potential due to $-q$: $-frac{kq}{d}$

Vnet​=kq/d​−kq​/d=0
