The conjugate of a complex number a + bi is a - bi. Thus, the conjugate of 2 - 3i is 2 + 3i.

The conjugate of a complex number a + bi is a - bi. Thus, the conjugate of 5 - 3i is 5 + 3i.

Pressure is defined as force per unit area, hence its dimension is M^1L^-1T^-2.

The dimension of velocity is M^0L^1T^-1.

Acceleration is defined as the change in velocity per unit time, so its dimensional formula is [M^0 L^1 T^-2].

Energy has the dimensional formula [M^1 L^2 T^-2], as it is defined as work done, which is force times distance.

Frequency has the dimensional formula [M^0 L^0 T^-1].

The gravitational potential energy is given by U = mgh, where h is the height above the reference point.

The compound CH3-CH2-CH(OH)-CH3 is 2-butanol, as the hydroxyl group is on the second carbon.

Phenol can be prepared by the hydrolysis of chlorobenzene using sodium hydroxide.

The speed of light is approximately 3 x 10^8 m/s.

The reactivity of haloalkanes in nucleophilic substitution reactions decreases in the order R-I > R-Br > R-Cl > R-F due to bond strength.

0.001 can be represented as 1 x 10^-3 in scientific notation.

Both Joule and Newton-meter represent the same unit of energy.

Propan-2-one, also known as acetone, has the structure CH3COCH3, indicating it is a ketone.

The unit for measuring frequency is Hertz (Hz).

The SI unit for measuring pressure is Pascal (Pa).

The SI unit for pressure is Pascal (Pa), which is equivalent to N/m².

Aldehydes contain the functional group -CHO, which is characterized by a carbonyl group (C=O) bonded to a hydrogen atom.

The sarcomere is the basic functional unit of skeletal muscle, responsible for muscle contraction.

The aorta is the largest artery in the human body, carrying oxygenated blood from the heart to the rest of the body.

Beryllium (Be) is the lightest alkaline earth metal.

Plasma is composed of approximately 90% water, with proteins, electrolytes, and nutrients making up the remaining 10%.

Hydrogen is the most abundant element in the universe, making up about 75% of its elemental mass.

Protium, which has no neutrons, is the most abundant isotope of hydrogen, making up about 99.98% of hydrogen found in nature.

P2O5 is the most acidic oxide among the given options, as it forms phosphoric acid in water.

P2O5 (phosphorus pentoxide) is the most acidic oxide among the given options.

Fluorine is the most electronegative element in the periodic table.

Rubidium (Rb) is the most electropositive element among the given options.

Potassium (K) is more reactive than Sodium (Na) and Lithium (Li) due to its larger atomic size and lower ionization energy.
