Explanation
Light year is a distance which light travels in one year.
Watt = Joule/second = Ampere × volt = Ampere2 × Ohm
Impulse = change in momentum = F × t
So the unit of momentum will be equal to Newton-sec.
Unit of energy will be kg-m2/sec2 .
Kg-m/sec is the unit of linear momentum.
[η] = ML-1 T-1 so its unit will be kg/m-sec.
6 × 10–5 = 60 × 10–6 = 60 microns.
Because temperature is a fundamental quantity.
Bxt is unitless. Therefore, Unit of B is m–1 s–1.
Because in SI system there are seven fundamental quantities.
1 Oersted = 1 Gauss = 10–4 Tesla.
Charge = current × time
Joule-sec is the unit of angular momentum where as other units are of energy.
Astronomical unit of distance.
As I = MR2 = kg-m2.
Curie = disintegration/second.
Unit of e.m.f = volt = joule/coulomb.
