(i) The size examines cannot be operated to derive relations other than product of power functions, for example, s = ut + 1/2 at2 or y = y0 cosωt and so on, cannot be derived openly.
(ii) The size examines cannot be operated to measure those relations that involve more than 3 unknowns, Though, we can use them to check the correctness of a relation even if variables are more than 3.
(iii) Even if a physical value relays upon 3 quantities, out of which two have similar dimension then dimensional analysis cannot be applied to derive such a formula but can be used to check the relation.
(iv) Numerical trigonometric ratios, constants and ratios which are dimensionless cannot be derived.
(v) Physical quantities having similar dimensions may not be the similar. For example [ML2T-2] is a dimensional relation for torque as well as work or energy.
Mass energy relation - The total energy of a body is the sum of its kinetic energy and rest mass energy. Particle having rest mass zero always move with the velocity of light.
Curie's law (P. Curie) The susceptibility, khi, of an isotropic paramagnetic substance is associated to its thermodynamic temperature T through the equation khi = C/T
Neural coding is a neuroscience based field mainly concerned with characterizing the relationship b/w the stimulus & the individual and ensemble neuronal responses or the relations
Aiming Above the Monkey Assume a zookeeper must shoot a banana from banana cannon to a monkey who hangs from the limb of a tree. This particular monkey has a habit of dropping

Anode rays were discovered by: (1)Goldstein (b)J. Stoney (3)Rutherford (4)J.J. Thomson Ans: (1)Goldstein
Q State Lenz's law. Lenz's law declares that the induced current produced in a circuit always flows in such a direction that it opposes the change or cause that produces it.
