Question
Chapter P8, Problem 1MCPE
To determine
Einstein’s discovery about space and time.
Expert Solution & Answer
Answer to Problem 1MCPE
Solution:
What Einstein discovered about space and time is that they are parts of one whole.
Explanation of Solution
In 4D reality, Space-Time is consisting of 3D (Length, Width and Height/Depth) and Time coordinates that defines ‘Whole’ or collectively called ‘Light-Cone’. The observed values of length, width, height/depth and time are the parts of Light-Cone.
Hence, space and time separately are the parts of one whole.
Option (b) is the correct option.
Conclusion:
What Einstein discovered about space and time is that they are parts of one whole.

- When current is flowing through the coil, the direction of the torque can be thought of in two ways. Either as the result of the forces on current carrying wires, or as a magnetic dipole moment trying to line up with an external field (e.g. like a compass). Note: the magnetic moment of a coil points in the direction of the coil's magnetic field at the center of the coil. d) Forces: We can consider the left-most piece of the loop (labeled ○) as a short segment of straight wire carrying current directly out of the page at us. Similarly, we can consider the right-most piece of the loop (labeled ) as a short segment straight wire carrying current directly into the page, away from us. Add to the picture below the two forces due to the external magnetic field acting on these two segments. Then describe how these two forces give a torque and determine if the torque acts to rotate the loop clockwise or counterclockwise according to this picture?
