The net torque is zero because the forces are equal and opposite, producing no rotational effect.

The resultant force is the sum of the two forces: 10 N + 15 N = 25 N.

Net force = 10 N + 15 N = 25 N.

The net force is the sum of the forces: 10 N + 5 N = 15 N.

Net force = 5 N + 10 N = 15 N.

Torque is directly proportional to the force applied; hence, the 10 N force produces more torque.

Resultant force = 5 N + 3 N = 8 N.

Torque is greater when the force is applied further away from the pivot, given equal magnitudes.

The net torque is zero because the torques produced by the two forces cancel each other out.

C_eq = 1 / (1/C1 + 1/C2) = 1 / (1/4 + 1/4) = 2 µF.

As the charges are brought closer, the potential energy of the system increases due to the repulsive force between like charges.

The electric fields due to both charges at the midpoint will cancel each other, resulting in a net electric field of 0 N/C.

According to Coulomb's law, force is inversely proportional to the square of the distance. If the distance is doubled, the force becomes one-fourth.

The electric fields due to both charges at the midpoint cancel each other, resulting in a net electric field of 0.

The electric fields due to both charges at the midpoint cancel each other, resulting in a net electric field of 0 N/C.

Potential energy U = k * q1 * q2 / r = (9 × 10^9 N m²/C²) * (q²) / 1m. For q = 1μC, U = 1 J.

The moment of inertia of the bottom disk is MR^2, and the top disk contributes an additional MR^2 due to the parallel axis theorem, giving a total of 2MR^2.

Vertically opposite angles are equal. Therefore, the vertically opposite angle is also 40 degrees.

Two lines are parallel if their slopes are equal, which occurs when a/d = b/e.

Both lines have the same slope (2) but different y-intercepts, indicating they are parallel.

Both lines have the same slope (2) but different y-intercepts, indicating they are parallel.

Lines with the same slope but different y-intercepts are parallel and will never intersect.

If the corresponding angles are equal, it indicates that the two lines are parallel.

If the sum of the interior angles on the same side of the transversal is greater than 180 degrees, the two lines must intersect.

When two parallel lines are cut by a transversal, the alternate interior angles are equal.

Perpendicular lines intersect at right angles, which measure 90 degrees.

Perpendicular lines intersect at right angles, which measure 90 degrees.

The angles formed by intersecting lines are supplementary. Therefore, 120 + x = 180, which gives x = 60 degrees.

The angles formed by intersecting lines are supplementary. Therefore, x = 180 - 40 = 140 degrees.

Vertically opposite angles are equal. Therefore, the vertically opposite angle is also 120 degrees.
