<span>The answer is A. The pump and the plastic are the only ones that create pressure compared to the other choices.
When you exert a force on the pump to a closed object such as plastic, the pressure inside the pump that it gives off makes the plastic full of air. Pressure is defined to be the force per unit area or the stress within a fluid. </span>
Answer:
molar mass of methane CH4
= C + 4 H
= 12.0 + 4 x 1.008
= 12.0 + 4.032
= 16.042g/mol
7.31 x 10^25 molecules x 1 mole CH4 = 121.43 moles
6.02 x 10^23 CH4 molecules
121.43 moles CH4 are present.
Explanation:
not to certain if this is right or not.. but hope it helps!
When placed inside of a magnetic field, the magnetic field that electrons generate aligns in the opposite direction of the applied magnetic field.
Also, someone who is very popular and attracts people has a charming personality. A powerful speaker that attracts many fans has an engaging way of speaking. A magnetic person is attracted to you as if by a magical magnetism. Both meanings of magnetic have to do with the force of attraction. Only ferromagnetic materials such as iron, cobalt and nickel are attracted to magnetic fields strong enough to be considered truly magnetic.
All magnetic fields contain energy, also called magnetic energy. In physics, it is a constant. Magnetic energy is a form of energy from moving charge carriers (electrons) because magnetic fields are generated by electric currents.
