Q: Answer the following question given this paragraph: Electricity and magnetism are inextricably linked. Under certain conditions, electric current causes a magnetic field. Under other conditions, a magnetic field can cause an electric current. A moving charged particle creates a magnetic field around it. Additionally, when a moving charged particle moves through a different magnetic field, the two magnetic fields will interact. The result is a force exerted on the moving charged particle. Q: Under certain conditions, electric current causes what type of field? Choices: - light - kinetic - seismic - magnetic A:
A: magnetic

Q: Answer the following question given this paragraph: Quantum numbers specify the arrangements of electrons in orbitals. Q: What type of numbers specify the arrangement of electrons in orbitals? Choices: - ionic numbers - fusion numbers - stream numbers - quantum numbers A:
A: quantum numbers
