Kinetic and potential energy:
Energy can exist in of 2 main forms. Kinetic energy is the kind of energy you probably think of right away when you imagine the energy. A person running, a car moving down , a speeding aircraft, a chamber of the superheated gas-all these things are visible manifestations of the kinetic energy, or energy in action. The dissipation of electrical power, over the time, is the form of kinetic energy too.
Potential energy is not as brightly apparent. When you raise the block of concrete into air, you are creating potential energy. You remember the units called as foot pounds, the best way to measure such energy, from school physics classes. If you raise a 1 pound weight a foot, it gains 1 foot pound of potential energy. If you raise it 100 feet, it gains 100 foot pounds. If you increase a 100-pound weight 100 feet, it will gain 100× 100, or 10,000, foot pounds of potential energy. This energy becomes evident if you happen to drop a 100-pound weight from a tenth-story window.
Resonance: When the frequency of driving force becomes equivalent to the natural frequency of an oscillating system, the driving force gives maximum energy and the oscillating
When you are talking about relative velocity of A with respect B then it''s like you are observing the motion of A while standing on B. That is, with respect to you, B is at rest.
Q. How much should be the voltage of an X-ray tube so that the electrons emitted from the cathode may give an X-ray of wavelength 1 A o after striking the target? λmin = 124

Q. Write any three medical applications of laser. Medical applications (i) In medicine micro surgery has befall possible due to narrow angular spread of the laser beam.
A stack emitting 85 g/s of NO has an effective stack height of 100 m. The wind speed is 3 m/s at 10 m, and it is a cloudy summer day. Estimate ground level NO concentration:
It is worth noting that positive charges have lines of forces moving out from them and negative charges have lines of forces entering them.for attraction of charges one charge must
