A sphere of mass m and radius r is on a smooth fixed inclined plane in equilibrium, if now the sphere is displaced by a small distance along the plane , what will be angular frequency of the resulting SHM (k=4M/3)( angle of inclination =30 degree)
Ans) 2pie(3/4)1/2
Surface gravity on Mars is roughly 1/3 that of the Earth. Consider you drop a rock initially at rest from a height Hm on Mars and it takes a time tg to hit the ground. From what he

HEAD-ON COLLISION: "If the centers of the colliding bodies stay moving along the similar straight line, the collision is said to be head-on collision".
a lead bullet moves horizontally with a velocity of 130ms and embedded into a cement wall after collision. if the specific heat capacity of lead = 130J/KgC and all heat produces is
Longitudinal Waves and Tuning Forks Sound waves are generates through vibrating objects. Whether it is the sound of a person's voice, the sound of a piano and the sound of a tr
You pull a simple pendulum of length 0.240 m to the side through an angle of 3.50 degrees and release it. a) How much time does it take the pendulum bob to reach its highest speed?
Capacitor construction: FIXED CAPACITORS Fixed capacitors usually consist of sheets of metal foil between which is sandwiched the dielectric, or alternatively the metal, s
Particle function: Protons The number of protons in an atom determines the kind of material: Eg. Hydrogen 1 proton Helium 2 protons Lithium 3 protons B
derive an expression for density of states and hence deduce an expression for carrier concentration of metals
In Thomson's effect we pact with only metallic rod and not with thermocouple as in Peltiers effect and Seebeck's effect. (That's why sometimes it is called as homogeneous thermo el
