Which colors will eject electrons? The higher energy blue light ejects electrons with higher kinetic energy compared to the green light. Which best explains what happens when an electron moves from an excited state to ground state? Which best explains what happens when an electron moves from an excited state to the ground state? The […]

Is a mini nuclear reactor possible? NASA is developing a nuclear power plant whose reactor is about the size of a garbage can. Called Kilopower, this fission power system could provide up to 10 kilowatts of electrical power continuously for at least 10 years—enough to run several households.

Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge. What are 4 main […]

What is the path of a charged particle in a magnetic field? If the field is in a vacuum, the magnetic field is the dominant factor determining the motion. Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. The particle continues to […]
