Answer: The object's mass, height off the ground, and the strength of gravity :)
Answer:
An atom behaves electically neutral because it has an equal number of protons and electrons.
Explanation:
There are three sub-atomic particles: neutrons, electrons and protons. Neutrons have a neutral charge; electrons have a negative charge; and protons have a positive charge. In a regular atom, there is an equal amount of electrons and protons, making a neutral charge.
Answer:
Hydrogen and helium are different elements. How can you use the plum pudding model to show how atoms of the two elements might be different from one another? Answer: Possible answer: The two types of atoms could have different amounts of positive fluid and different numbers of electrons.
295k=22°c
1050k=777°
total heat needed=
(0.475)(777-22)(specific heat capacity of aluminium)+(0.475)(specific latent heat of aluminium)
