Can generator be used as motor? In principle, any electrical generator can also serve as an electric motor, or vice versa. In hybrid vehicles and other lightweight power systems, a “motor–generator” is a single electric machine that can be used as an electric motor or a generator, converting between electrical power and mechanical power. How […]
What is the uses of technology?
What is the uses of technology? Technology has evolved and shaped our workplaces in many ways, through the adoption of tools like the internet and email for communications, word processing, spreadsheets and presentations for office productivity, electronic databases for record keeping, and robots and artificial intelligence for automation. What does technology mean for you? Technology […]
Why are steam engines inefficient?
Why are steam engines inefficient? Steam engines are extremely inefficient, wasting around 80–90 percent of all the energy they produce from coal. That means they have to burn enormous amounts of coal to produce useful amounts of power. It’s inefficient because energy is wasted as the heat and steam travel from the fire, via the […]
Do I need to discharge a capacitor?
Do I need to discharge a capacitor? You must discharge the capacitors before working on power supply circuits so you won’t get shocked. There are three different ways to discharge large filter capacitors in a power supply: with a screwdriver, the leads of a socketed 100 watt light bulb, and the leads of a high-wattage […]
What happens if a hydrogen car catches fire?
What happens if a hydrogen car catches fire? The vehicles are designed with a thermal pressure relief device (TPRD) on the tank that would discharge if the car was engulfed in a fire. If a fuel leak were to occur, the hydrogen would disperse upward rapidly, and if the TPRD were activated, the tank would […]
How many joules is lethal?
How many joules is lethal? 50 Joules How many joules can a human punch? 400 joules How many joules can break a bone? 375 Joules How many joules does it take to crack a skull? We scanned the models after impact and compared the resulting fractures to the victim’s skull. The energy necessary for the […]
What is the term for the angle at which light undergoes total internal reflection?
What is the term for the angle at which light undergoes total internal reflection? This angle of incidence is known as the critical angle; it is the largest angle of incidence for which refraction can still occur. For any angle of incidence greater than the critical angle, light will undergo total internal reflection. Which of […]
How does the 1st and 2nd law of thermodynamics apply to biological systems?
How does the 1st and 2nd law of thermodynamics apply to biological systems? Two fundamental concepts govern energy as it relates to living organisms: the First Law of Thermodynamics states that total energy in a closed system is neither lost nor gained — it is only transformed. The Second Law of Thermodynamics states that entropy […]
Where is an 18 wheeler blind spots?
Where is an 18 wheeler blind spots? Because of the massive size of 18-wheelers and other big commercial trucks, they have many blind spots. For instance, 18-wheelers have a blind spot at the front-end of the truck, on both sides; just below and behind the driver-side window; and directly behind the truck. What are blind […]
Why does glass amplify sound?
Why does glass amplify sound? It happens because glass resonates at frequencies we can hear. The resonant frequency of the glass changes with its thickness. When energy at that frequency meets the glass, it causes the glass to vibrate like a drum head. How do you physically amplify sound? Untitled Document. Sounds can be made […]
