Electromagnetic induction refers to the generation of electric current in a conductor due to a changing magnetic field.

Polarization refers to the orientation of the oscillations of light waves in a particular direction.

The photoelectric effect is primarily used in solar panels to convert light energy into electrical energy.

The photoelectric effect is the phenomenon where electrons are emitted from a metal surface when it is exposed to light of sufficient frequency.

The pKa of acetic acid is approximately 4.76.

Most carboxylic acids have a pKa range of about 4-5.

The pKa value of acetic acid is approximately 4.76.

A strong base has a pKb value less than 0, indicating high basicity.

Aniline has a pKb value around 9, indicating it is a weak base.

Methylamine is a weak base, so its pKb value is less than 7.

A weak base has a pKb value greater than 7.

The plural form of 'child' is 'children'.

To find inflection points, set f''(x) = 0. f''(x) = 6x - 12 = 0, x = 2. f(2) = 4.

Solving the equations simultaneously, we find x = 2 and y = 3. Thus, the point of intersection is (2, 3).

Setting 3x + 1 = -x + 5 gives 4x = 4, thus x = 1. Substituting x back gives y = 4. The intersection point is (1, 4).

Poisson's ratio (ν) = Lateral strain / Longitudinal strain = 0.002 / 0.005 = 0.4.

Poisson's ratio (ν) = -lateral strain / longitudinal strain = -0.008 / 0.02 = 0.4.

Poisson's ratio (ν) = Lateral strain / Longitudinal strain = 0.02 / 0.01 = 2.

Potential due to a dipole V = (1/4πε₀) * (p * cosθ) / r². At 1 m, it is negligible.

Using Ohm's law, V = I * R = 2A * 10 ohms = 20V.

Using Ohm's Law, V = I * R = 2A * 10Ω = 20V.

Using Ohm's Law, V = I * R = 4A * 10Ω = 40V.

Using Ohm's law, V = I * R = 2 A * 5 Ω = 10 V.

Using Ohm's law, V = IR = 2A * 5Ω = 10V.

In a balanced Wheatstone bridge, the potential difference across the galvanometer is zero, indicating no current flows through it.

Potential difference V = E * d = 50 N/C * 2 m = 100 V.

Potential difference V = E * d = 5 N/C * 3 m = 15 V.

Potential difference V = W/Q = 0.02 J / (5 × 10^-6 C) = 4000 V = 4 V.
