Potential difference V = E * d = 50 N/C * 0.4 m = 20 V.

Potential difference V = E * d = 400 N/C * 0.5 m = 200 V.

At maximum displacement, potential energy is maximum and kinetic energy is zero.

Potential energy U = k * q1 * q2 / r = (9 × 10^9 N m²/C²) * (3 × 10^-6 C) * (4 × 10^-6 C) / 0.2 m = 54 J.

Potential energy U = k * q1 * q2 / r = (9 × 10^9 N m²/C²) * (3 × 10^-6 C) * (4 × 10^-6 C) / 0.3 m = 0.36 J.

Potential energy (PE) is calculated using the formula PE = mgh. Here, PE = 2 kg × 9.8 m/s² × 10 m = 196 J.

Potential energy U = k * q1 * q2 / r = (9 × 10^9 N m²/C²) * (3 × 10^-6 C) * (4 × 10^-6 C) / 0.2 m = 54 J.

The potential energy (U) stored in a capacitor is given by U = 1/2 CV^2.

The potential energy (U) stored in a capacitor is given by the formula U = 1/2 CV², where C is the capacitance and V is the voltage across the capacitor.

Power P = I^2 * R = (3A)^2 * 10Ω = 9 * 10 = 90W.

Power P = I^2 * R = (2 A)^2 * 10 Ω = 4 * 10 = 40 W.

The prefix for 10^6 is Mega (M).

Aspirin is chemically known as acetylsalicylic acid, which is used for pain relief and anti-inflammatory purposes.

Asexual reproduction allows for rapid population increase as it does not require a mate.

Sexual reproduction leads to genetic diversity, which can enhance survival in changing environments.

Nuclear fusion is primarily applied in hydrogen bombs, where fusion reactions release immense energy.

Recombinant DNA technology is used to enhance crop yield, provide pest resistance, and improve nutritional value, making option 'All of the above' the correct answer.

Recombinant DNA technology is used in various medical applications including the production of insulin, gene therapy, and vaccines.

Genetic similarity is the primary basis for the classification of living organisms.

Probiotics are beneficial bacteria that improve gut health and aid in digestion.

Probiotics are beneficial bacteria that help enhance gut health and improve digestion.

AIDS is caused by the Human Immunodeficiency Virus (HIV), which is a virus.

Habitat destruction is the primary cause of biodiversity loss, as it leads to the loss of species and ecosystems.

Tuberculosis is primarily caused by the bacterium Mycobacterium tuberculosis.

K-selected species typically exhibit high parental care and invest more resources in fewer offspring.

The primary characteristic of a redox reaction is the transfer of electrons between species.

Alkaline earth metals typically have a +2 oxidation state due to the loss of two electrons.

Amorphous solids have short-range order but lack long-range order, unlike crystalline solids.

The primary characteristic that distinguishes living organisms from non-living things is their ability to reproduce, which is essential for the continuation of species.

Plasma is composed of approximately 90% water, which serves as a solvent for various substances in the blood.
