a. air currents spin a propeller that drives a turbine-electrical generator.

b. hot air converts water to steam and drives a turbine-electrical generator.

c. air currents collide with a special cell that releases electrons, which forms electricity.

i think its

b

explanation:

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. 

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
