Mechanical energy E of particle, system or object is explained as the sum of kinetic energy K and potential energy U, i.e. E = K + U. It is a scalar quantity having dimensions [ML2T-2] and SI unit joule.
(i) It relays on frame of reference.
(ii) A body may have mechanical energy without having either kinetic energy or potential energy. Though, if both potential and kinetic energies are zero, mechanical energy will be zero. The result may or may not be true, i.e., if E = 0 either both KE and PE are zero or PE negative and KE positive such that KE + PE = 0
The Time Base Control 3 Shows the effect of changing the time base control on the display when there is an input voltage varying in time when the frequency of the voltage is hi
In a single slit diffraction pattern the distance between the first minimum on left to first minimum on the right is 0.054 cm for a light of wavelength 5890 Å. Determine
A man exerts a force of 310 N on a lever to raise a crate with a mass of 910 kg. If the efficiency of the lever is 78 percent, what is the lever's IMA?
Q. What is an electric dipole? Define: the dipole moment. Two equal as well as opposite charges separated by a very small distance constitute an electric dipole. Instances amm
Resistance measurements: An example of how to make AC voltage measurements is shown in the diagram below. Once again, the red and black test leads are connected to the '+' and
Kepler's 1-2-3 law Another formulation of Kepler's third law, that relates to the mass m of the primary to a secondary's angular velocity omega & semimajor axis a: m o= ome
Ergosphere The region about a rotating black hole, among the event horizon & the static limit, where rotational energy can be extracted through black hole.
In an adiabatic process, the body neither absorbs heat nor does it refuse energy, i.e. in this phenomena there is no heat exchange (Δ Q = 0). Thus from first law of thermodynam
