Answer:
Protons have about the same mass as electrons is false
Explanation:
Electrons and protons have the same magnitude on charge but opposite sign
: charge of electron
: charge of proton
Neutrons have no charge.
An atom is composed of protons and neutrons in the nucleus and electrons surrounding it, so a neutral atom has the same number of protons and electrons to has a net charge of zero. So, all the facts mentioned are true.
The false one is that protons have about the same mass as electrons, because the mass of an electron is 
and the mass of a proton is 
so the mass of a proton is a lot of bigger than electron mass.
Answer:
2 number
Explanation:
Displacement is a vector. This means it has a direction as well as a magnitude and is represented visually as an arrow that points from the initial position to the final position.
Answer:
It's because it tips over the threshold from nucleate boiling, which we can see, to convection boiling, which we can't. ... Even if the steam stayed in the pot, it would still stop boiling when you removed the heat. The steam and water in a liquid/vapour mixture are at the same temperature (100ºC).
