Answer: C
Explanation:
when more volts are in a battery the more current you receive.
Answer:
The pressure value changes 400 % relative to the initial value.
Explanation:
Let suppose that the gas behaves ideally and represents a closed system, that is, a system with no mass interactions so that number of moles is conserved (
). Since the variables involved in the isothermal process are pressure (
) and volume (
). Finally, the process is represented by the following relationship:
(1)
Where:
- Initial and final pressures.
- Initial and final volumes.
If we know that 
, 
and 
, then the final pressure of the closed system is:
The pressure value changes 400 % relative to the initial value.
Radioisotopes is a atom with unstable nuclei. They also decay to change different from the electrons over time.

Answer:
Wrapping the bar with a coil of wire that has an electric current.
Explanation:
To cause an iron bar to start generating a magnetic field, wrap the bar with a coil that has an electric current.
- This process is known as making magnetics using an electric current.
- There is an interaction between electric and magnetic fields.
- Electrical current can be induced by magnetic fields and magnetism can be induced by electric currents.
Wrapping the bar with a coil of wire that has electric current can cause an iron bar to start producing magnetic fields. This way, the iron bar becomes a magnet.
