A magnetic field cannot MCQ with Answer and Explanation

Explanation:
Resistance of a bulb is R = V^2 / P. The 60W bulb has a higher resistance than the 100W bulb. When connected in series, the exact same current (I) flows through both. The power consumed (which determines brightness) is given by P = I^2R. Since the 60W bulb has higher resistance (R), it consumes more power and glows brighter.

Explanation:
L = r × p: [L][MLT⁻¹] = [ML²T⁻¹]. Same as Planck's constant. Memory tip: 'Angular momentum: [ML²T⁻¹]; action quantities share dimensions'. Dimensional analysis frequently tested in competitive exams.

Explanation:
Kepler's 3rd law: T² ∝ R³ => T' = T (4)^(3/2) = T×8 = 8T.
