Dear friends units is a important part of physics so most probably chance to more than two question in UPTET 2013.  Name of 7 fundamental units—Fundamental Quantities —- UnitsLength.                           —-meter Mass.                          —-kilogramTime.                       —-second                                  Temperature.        —-kelvin (K)                                  Electric current.   —-ampere(A)                                  Luminous intensity -candela(cd)                                  Molecular quantity -mole.    (mole)                                1 day =86400second                               Tera (10¹²)                         Giga (10^9)                      Mega (10^6)                   Kilo (10³)              Hecto(10²)         Deca(10¹)               Base         Decided(10-¹)                 Centi(10-²)                     Mili (10-³)                         Micro (10-6)                               Nano (10-9)                                    Pico (10-¹²)Note– 1angstrom (A°)=10-¹° meter    Use for Light wave .1 Light year=9.46×10¹5 meter                    =10¹6meter(aprox)Momentum unit =kg×ms-¹Impulse of aforce=newton×secondUnit of Motion =ms-¹    Acceleration =ms-²(^V/s)                Force=kg×ms-² (F=ma)   Also known as=newtonUnit of Gravitational force=newton …
