Answer:An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999.
Explanation:
B) It was transformed into 350 J of heat energy.
Explanation:
The remaining 350J of energy must have been transformed into 350J of heat energy.
A fan works by converting electrical energy into heat energy.
- According to the third law of thermodynamics "no system is 100% efficient". The conversion of the energy from one form to another involves a lost in energy.
- Heat is one very familiar way by which energy can be lost.
- Some component energy is used to heat the fan in the process and it is a wasted energy.
- Friction surfaces a heat energy in this process.

Answer/Explanation:
In June 1998 in Japan a scientist discovered that neutrinos (which is a type of particle) has weight, mass. This was later proven with some very convincing strong evidence.
