(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
Dalton turned Democritus' views on atoms into a scientific theory by employing experimental methods. Atoms can join or detach during chemical processes, but they never transform into a different atom.
Dalton was an excellent polymath, a natural philosopher, and a real scientist. His thorough investigations prompted him to suggest an early atomic theory for which exceptions would be difficult to uncover today:
Dalton offered the following:
Atoms are microscopic particles that make up elements. Atoms of the same element have the same size and mass; however, atoms of other elements have varying sizes and masses when compared to atoms of other elements. Subdivision, creation, and destruction of atoms are all impossible.
All of these ideas were developed after a great deal of testing. Other researchers may replicate his work, and new findings could be included into this atomic idea.
Democritus, on the other hand, was a 5th-century BC Greek philosopher. He conducted no experimental work as far as we know, and none of his publications have survived. He postulated that matter was made up of a single indivisible element known as an atom; the word atom originates from the Greek word oos, which meaning "uncuttable" or "indivisible." So the name atom might be a homage to Democritus.

Option D.
A voltaic cell need tha anode, the cathode and the electrolyt to work.
Volitmeter is just an equipment to measure the functioning of the voltaic cell.
Explanation:
The question involves converting from one unit (Kilometres) to another unit (Astronomical unit)
The relationship between both units is given as;
1 Km = 6.68459e-9 Au
Kulper belt
6.5 billion km = 6.5e9 Km
1 Km = 6.68459e-9 Au
6.5e9 Km = x
Solving for x;
x = 43.45 Au
Alpha Centauri
44 trillion km = 4.4e13
1 Km = 6.68459e-9 Au
4.4e13 km = x
Solving for x;
x = 294121.83 Au
