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. Which is the smallest nuclear power plant […]

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 […]

Which angular velocity is greater a second hand minute hand and hour hand of a clock? The second hand goes through 2π radians in 1 min, or 2π radian/60 seconds, so ω = π/30 rad. s-1 = 0.03 rad. s-1. The minute takes one hour = 60 s/min × 60 min = 3600 s to […]

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 […]

Does the lag time get shorter or longer the further you get from the epicenter? Longer time lag means you are farther from the epicenter. Shorter time lag between waves means the waves are nearly on top of each other, meaning you are nearer to the epicenter. How can you prove an epicenter was where […]
