The correct order is T, S, R, Q, P based on the given conditions.

The order based on the scores is R > P > Q and T > S > P. Since T is greater than S and S is greater than P, T is the highest scorer.

The order of scores is R > P > Q and T > S > P. Thus, T is the highest scorer.

The scores in descending order are S (95), Q (90), P (85), T (80), R (75). Thus, S is first, Q is second.

The scores in descending order are D (95), B (90), A (85), E (80), C (75). Thus, A is in the second position.

C scored 75 marks, which is the third highest, so C ranks 3rd.

The scores in descending order are S (95), Q (90), P (85), T (80), R (75). Thus, S is first, Q is second.

The electric field due to a charged plane sheet is directly proportional to the surface charge density. Therefore, if σ is doubled, E also doubles.

The electric field inside a uniformly charged sphere is zero.

The electric field inside a charged conductor in electrostatic equilibrium is zero.

The magnetic field at the center of a circular loop of radius R carrying current I is given by B = μ₀I/(2πR).

According to Ampere's Law, the line integral of the magnetic field around a closed loop equals μ₀ times the total current enclosed by the loop.

The total electric flux through a closed surface is given by Φ = ΣQ_enc/ε₀, where Q_enc is the total charge enclosed.

According to Gauss's law, the total electric flux through a closed surface is proportional to the total charge enclosed.

The total moment of inertia of a composite body about the same axis is the sum of the individual moments of inertia.

The total moment of inertia of a composite body is the sum of the individual moments of inertia: I_total = I1 + I2.

When the object is at infinity, the rays converge at the focus of the convex lens.

When the object is at the focus of a convex lens, the rays of light emerge parallel, resulting in no image being formed.

The magnetic field at the center of a loop is inversely proportional to the radius. If the radius is halved, the magnetic field quadruples.

For points outside the cylinder, B = μ₀I/2πr.

Using Ampere's Law, B = μ₀I/2πR for points outside the cylindrical conductor.

The damped frequency is less than the natural frequency due to the effect of damping.

Using the grating equation d sin θ = nλ, where d = 1/500000 m, n = 1, and λ = 600 x 10^-9 m, we find θ ≈ 30 degrees.

If the slit width is halved, the width of the central maximum increases because the angle for the first minimum increases.

The central maximum in a single-slit diffraction pattern is wider than all other maxima.

For a first-order reaction, the half-life is independent of the initial concentration. Therefore, it remains 10 minutes.

For a first-order reaction, the half-life is given by the expression t1/2 = 0.693/k.

For a first-order reaction, the half-life is independent of the initial concentration.

RMS speed is proportional to the square root of temperature, so v_rms at 600 K = 500 * sqrt(600/300) = 707 m/s.

Using v_rms = sqrt(3RT/M), we calculate v_rms = sqrt(3 * 8.314 * 300 / 0.028) which gives approximately 600 m/s.
