Q. Consider two inertial reference frames. when an observer in each frame measures the following quantities, which measurement made by two observers must yield the same results?1. the distance between two events2. the value of the mass of a proton3. the speed of light4. the time interval between two events5. newton's first law6. the order of elements in the periodic table7. the value of the electron charge
