Are bevs or hydrogen fuel cell vehicles a more promising transportation technology for the future? (this is question #3 from p. 608.) should car companies be required to produce electric cars?

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
