A clock, which loses uniformly is 15 minutes fast at 9 am on 3rd of the December and is 25 minutes less than the correct time at 3 pm on 6th of the same month. At what time it was correct ?

In a view unit system, 1 unit of time is equal to 10 second, 1 unit of mass is 5 kg and 1 unit of length is 20 m . In the new system of units 1 unit of energy is equal to :

A : Coordination number of both Na^(+) and Cl^(-) NaCl is 6. R : Second coordination number of Cl^(-) in the NaCl unit is 12.

In a new system of units known as RMP, length is measured in 'retem', mass is measured in 'marg' and time is measured in 'pal'. 100 retem=1.0 meter 1.0 marg = 10^(-3) kilogram 10 pal=1.0 second In the given table some unit conversion factors are given . Suggest suitable match.

The equation of motion of a particle moving along a straight line is s=2t^(3)-9t^(2)+12t , where the units of s and t are centrimetre and second. The acceleration of the particle will be zero after
