Santiago Friedman · Answer 1

true a and c

Explanation:

The theory of special relativity is formulated under two postulates

* that the laws of physics are the same in all inertial systems

* that the speed of light in the vacuum is constant for all systems

with these postulates the energy of a particular is

E = K + m c²

where the last term is called energy at rest

a) True. only when m = 0 the energy of the particle is scientific energy

be False. Nothing can go faster than light

c) Right. In a material medium the speed of light depends on the measurement reference frame

d) False For a particle of finite mass the energy must be greater than the energy at rest
