What are the six stages of Kohlberg moral development? Like Piaget, subjects were unlikely to regress in their moral development, but instead, moved forward through the stages: pre-conventional, conventional, and finally post-conventional. Each stage offers a new perspective, but not everyone functions at the highest level all the time. What is Carol Gilligan’s theory of […]

How many times do pulsars spin?
How many times do pulsars spin? The fastest known millisecond pulsars can rotate more than 700 times per second. How do pulsars die? Since the light energy escapes, the production of the energy beam robs energy from the pulsar, so the pulsar’s rotation slows down (angular momentum does slowly decrease). Eventually, the pulsar dies away […]

Is electricity the movement of electrons? Electricity is the movement of electrons between atoms. Why do electrons move from negative to positive? A: Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets […]

Why is there vacuum above the level of mercury in a mercury barometer?
Why is there vacuum above the level of mercury in a mercury barometer? The top of the barometer is filled with nothing (vacuum) because the mercury must have the space to expand and contract without any other force affecting it; a gas or liquid in the top would have its own pressure against the mercury […]
What holds a nucleus together?
What holds a nucleus together? The strong nuclear force. At extremely short range, it is stronger than electrostatic repulsion, and allows protons to stick together in a nucleus even though their charges repel each other. Remember that the size of the nucleus is really small compared to the size of an atom. What makes a […]
