The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.

Expert Solution

Step 1

Ruth left a wax candle in her car for several hours on a summer (warm) day.

Due to the high temperature, the heat is trapped inside the car which melts the wax candle.
