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 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 hardest engineering major?
What is the hardest engineering major? 1. Electrical Engineering Electrical Engineers are primarily focused on the physics and mathematics of electricity, electronics, and electromagnetism. Students consider electrical engineering to be the toughest major mostly because of the abstract thinking involved. Which engineering is best in future? Best Engineering Courses for Future Aerospace Engineering. Chemical Engineering. […]
Does the lag time get shorter or longer the further you get from the epicenter?
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 […]
What is the difference between infrared camera and thermal camera?
What is the difference between infrared camera and thermal camera? Active IR systems use short wavelength infrared light to illuminate an area of interest. Some of the infrared energy is reflected back to a camera and interpreted to generate an image. Thermal imaging systems use mid- or long wavelength IR energy. Can an infrared camera […]
How is a rainforest different from other forests?
How is a rainforest different from other forests? A rainforest is an ecosystem characterized by heavy rain and a dense tree canopy that lets very little light through to the understory. A forest ecosystem must receive over 60 inches of rain per year to be considered a rainforest. The temperate rainforest biome has fewer species […]
