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 […]
Which colors will eject electrons?
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 […]
How many watts does an escalator use?
How many watts does an escalator use? A continuously running escalator of the kind you’d find in airports or subway stations—35 feet high with a 40 horsepower motor—would use around 60,000 kWh annually. (For comparison’s sake, the average American home consumes 11,040 kWh in a year.) How much electricity does and elevator use? According to […]
What are the odds of a head hair originating from one person to another a pubic hair?
What are three parts of an atom?
What are three parts of an atom? Our current model of the atom can be broken down into three constituents parts – protons, neutron, and electrons. 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?
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 […]
How can you increase the density of air?
How can you increase the density of air? Density and pressure/temperature As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases. Air density will decrease by about 1% for a decrease of 10 hPa in pressure or 3 °C increase in temperature. What factors affect air density? Pressure, […]
What is the similarities between qualitative and quantitative?
What is the similarities between qualitative and quantitative? One similarity between qualitative and quantitative research is that raw data is ultimately qualitative. Even though numbers are unbiased, the researcher still has to choose some numbers and disregard others. What is a quantitative observation example? Examples of quantitative observation include age, weight, height, length, population, size […]
