While travelling at a higher altitude, a person complains of dizziness and vomiting sensation. Which part of the inner ear is disturbed during the journey?

A train travels between two stations ambala and Amritsar. While goind from Ambala to Amritsar, it takes 3 hours and its average speed is 100km/hr. when coming back from Amritsar of Ambala, it takes 2 hours and it average speed is 150 km/hr. obtain the average speed during the whole journey?

The earth has a radius of 6400 km . The inner core of 1000km radius is solid. Outside it, there is a region from 1000 km to a radius of 3500 km which is in molten state. Then again from 3500 km to 6400 km the earth is solid.Only longitudinal (P) waves can travel inside a liquid. Assume that the P wave has a speed of 8km s^(-1) in solid parts and of 5 km s^(-1) in liquid parts of the earth. An earthquake occur at some place closer to the surface of the earth.CAlculate the time after which it will be recorded in a seismometer at a diametrically opposite point on the earth if wave travels along diameter?

Bohr model is a system consisting of small, dense nucleus surounded by orbting electrons. The electrons travel in defined circular orbits around the nucleus for which orbital angular momentum is an itnegral multiple of h/(2pi) . While rotating in allowed orbits the electrons does not raidate energy. Electromagneitc radiations are emitted when the electrons jumps from a higher orbit (E_(n_i)) to a lower orbit (E_(n_f)) When an electron jumps from higher to lower orbit energy is:

Bohr model is a system consisting of small, dense nucleus surrounded by orbiting electrons. The electrons travel is defined circular orbits around the nuclues which orbital angular moementum is an integral multiple of h/(2pi) . While rotating in allowed orbits (stationary orbits) the electron does not radiate energy. electromagnetic radiations are emitted when the electron jumps from a higher orbit (E_(ni)) to a lower orbit (E_(nf)) . The total energy of the electron in an atom is negative. It suggests that
