1.	The number of base units for measuring physical quantities according to the SI system are ____(a) 1(b) 10(c) 7(d) 8This question was addressed to me in an international level competition.My question is from The International System of Units topic in chapter Units and Measurements of Physics – Class 11
Answer» Right answer is (c) 7 For explanation I WOULD SAY: There are 7 base units for measuring physical quantities according to the SI system. They are kilogram (kg) for mass, second (s) for time, kelvin (K) for temperature, ampere (A) for electric current, mole (MOL) for the amount of a substance, candela (cd) for luminous INTENSITY, and meter (m) for distance.
