The crucible is not fired, as the procedure suggests, but had retained some impurities from previous use (or it could only be oily smudges from fingers). the mass of the "dirty" crucible is recorded. however, the impurities are burned off in the experiment. will the reported mass of the final product be too high, too low, or unchanged as a result of this technique error? explain.

the device is called “ rocket engine”

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
