Don’t worry I will get the HSC Maharashtra State Board, Physics exam paper, so that it would be easy for you to prepare. Here is the exam paper The buckling of a beam is found to be more if _______. (A) the breadth of the beam is large. (B) the beam material has large value of Young’s modulus. (C) the length of the beam is small. (D) the depth of the beam is small. The number of degrees of freedom for a rigid diatomic molecule is _______. (A) 3 (B) 5 (C) 6 (D) 7 Attempt any SIX: [12] i. State Kepler’s law of orbit and law of equal areas. ii. A car of mass. 1500 Kg rounds a curve of radius 250m at 90 Km/hour. Calculate the centripetal force acting on it. iii. Draw a neat labelled diagram for Ferry’s perfectly black body. iv. A mass M attached to a spring oscillates with a period of 2 seconds. If the mass is increased by 2 Kg, the period increases by 1 second. Find the initial mass, assuming that Hooke’s law is obeyed. v. Differentiate between free and forced vibrations. vi. The surface tension of water at 0°C is 75.5 dyne/cm. Find surface tension of water at 25°C. [α for water = 0.0021/°C] vii. Derive the relation between surface tension and surface energy per unit area. viii. A wheel of moment of inertia 1 Kgm2 is rotating at a speed of 40 rad/s. Due to friction on the axis, the wheel comes to rest in 10 minutes. Calculate the angular momentum of the wheel, two minutes before it comes to rest.
