Special Relativity help

Question 1 (2 points) Select all that are true. Using Maxwell's equations it is possible to show that electromagnetic waves must travel at a constant speed (c 3x10 8 m/s) The only assumption needed for special relativity to work is for nothing in the universe to go faster than the speed of light. The only assumption needed for special relativity to work is for the speed of light to be a constant in the universe. Assuming the speed of light is a constant implies that both time and length are a property of the observer and not a constant value. Question 2 (1 point) Simultaneity (being able to say two things happened at the same time) is still a useful concept when using special relativity True False Question 3 (1 point) Many things in physics are defined as a relative quantity. For example, potential energy due to gravity is defined relative to the ground, the amount of charge something has is defined relative to zero net charge. Very few properties in physics are defined on an absolute scale (one of these properties we did last semester was temperature, when measured in Kelvin). Special Relativity discuses another (new) physical quantity on an absolute scale. What is this new absolute physical quantity Time Distance Energy Speed
