First, find the equivalent resistance: 1/R_eq = 1/4 + 1/8 = 3/8, so R_eq = 8/3Ω. Then, I = V/R_eq = 24V / (8/3)Ω = 9A.

First, find the equivalent resistance: 1/R_eq = 1/5 + 1/10 = 3/10, R_eq = 10/3Ω. Then, I = V/R_eq = 20V / (10/3)Ω = 6A.

Using Ohm's law, I = V/R = 9V / 3Ω = 3A.

Power is given by P = V²/R = (9V)² / 3Ω = 81V² / 3Ω = 27W.

Power P = V²/R = (9V)² / 3Ω = 81 / 3 = 27W.

Using Ohm's Law, R = V/I = 24V / 6A = 4Ω.

In a circuit with an inductor, the current increases gradually due to the inductor's opposition to changes in current.

Using Ohm's Law, V = I * R = 5A * 10Ω = 50V.

Power is given by P = I²R. If I is doubled, P becomes (2I)²R = 4I²R, which means power quadruples.

According to Ohm's law, I = V/R. If R is doubled, I will be halved.

According to Ohm's law, I = V/R. If R is halved, I will double.

Using Ohm's Law, R = V / I = 24V / 3A = 8Ω.

According to Ohm's law, I = V/R. If V is doubled, I also doubles.

Number of boys = 30 - 18 = 12. Probability = 12/30 = 2/5.

According to the First Law of Thermodynamics, ΔU = Q - W. Here, ΔU = 100 J - 40 J = 60 J.

Removing a reactant will shift the equilibrium to the left to produce more reactants, according to Le Chatelier's principle.

According to the first law of thermodynamics, if the internal energy increases, it implies that either work is done on the system or heat is added to the system.

The focal length of a concave lens is considered negative as it diverges light rays.

The focal length of a concave lens is negative, indicating that it diverges light rays.

Using the Nernst equation, E = (0.0591/n) log([C1/C2]), where n=1.

In a concentration cell, the electrodes are made of the same metal but have different concentrations of the electrolyte.

The genotype of the F1 generation from a cross between TT and tt will be Tt (all offspring will be heterozygous).

The height of the F1 generation will be tall, as tall is the dominant trait.

The arrangement of particles in a crystal lattice is primarily determined by intermolecular forces, which dictate how particles pack together.

In a cyclic process, the net work done is equal to the net heat added to the system, as the internal energy returns to its initial state.

In a damped harmonic oscillator, the amplitude decreases over time due to energy loss.

In a Daniell cell, Zinc acts as the anode.

The central maximum has the maximum intensity because all light waves arrive in phase at this point, leading to constructive interference.

The expected phenotypic ratio in a dihybrid cross is 9:3:3:1.

Fringe width (β) is given by β = λD/d. If λ is halved, β will also be halved.
