Answer:
The number of neutrons.
Explaination:
The atoms of carbon 12 contain 6 neutrons while the atoms of carbon 14 contain 8 neutrons
Answer:
4.80 seconds
Explanation:
The velocity of sound is obtained from;
V= 2d/t
Where;
V= velocity of sound = 329.2 ms-1
d= distance from the wall = 790.5 m
t= time = the unknown
t= 2d/V
t= 2 × 790.5/ 329.2
t= 4.80 seconds
Answer:
C. My soup will cool down because of radiation.
Explanation:
Since, there is vacuum between hot soup and its outside wall, then heat can not flow through conduction and convection.
The heat then only flows through radiation.
Therefore, the soup will not cool down because of convection or conduction by because of radiation.
Answer:
deductive reasoning usually follows steps .
- That is, how we predict what the observations should be if the theory were correct
Electrons: negative charge
Protons: positive charge
Neutrons: negative charge
The atom would have to have more electrons than protons
Hope this helps :)
