a calorie is a unit of heat or energy and it equals about 4.2J, where `1J=1kgm^2s^(-2)`. suppose we employ a system of units in which the unit of mass equals `alpha`kg, the unit of length equals `beta` meter, the unit of time is second. show that a calorie has a magnitude `4.2alpha^(-1)beta^(-2)gamma^2` in terms of new units.
