Can hydrogen be produced from sea water? “The only sustainable way to do that is to use renewable energy and produce it from water. So, the holy grail of producing hydrogen would be to combine the seawater and the wind and solar energy found in coastal and offshore environments.” Despite the abundance of seawater, it […]

What is hydrogen bonding What are its types explain with examples? Hydrogen bond is a electrostatic attraction between a hydrogen atom which is bond to a more electronegative atom such as Nitrogen, Oxygen, fluorine. These are two types of hydrogen bonds :- 1) Intermolecular Hydrogen bonding :- It occurs between two separate molecules. Eq :- […]

Can you leave garden hoses out all winter? A: Hoses can be stored outside as long as you make sure to drain all of the water from the hose. Hoses can be drained easily by running them over a tall place where gravity forces water to exit the hose. This ensures that the hose won’t […]

What are the causes of hysteresis? Hysteresis loss is caused by the magnetization and demagnetization of the core as current flows in the forward and reverse directions. As the magnetizing force (current) increases, the magnetic flux increases. How does hysteresis affect accuracy? IEC 61298-2 states that accuracy must include Hysteresis, Non-Repeatability and Non-Linearity. Hysteresis is […]

What are vector types? Types of Vectors List Zero Vector. Unit Vector. Position Vector. Co-initial Vector. Like and Unlike Vectors. Co-planar Vector. Collinear Vector. Equal Vector. What is a vector in science? Vectors are used in science to describe anything that has both a direction and a magnitude. The ball’s velocity vector describes its movement—the […]

How does current change if resistance is doubled? if resistance is doubled then the current would be halved as resistance is inversely proportional to the current flowing in a circuit. that is if the resistance is doubled the current would be halved. What happens to resistance when voltage is doubled? So doubling or tripling the […]

What is a good mile time for my age? Average running speed per mile in a 5K Age Men (minutes per mile) Women (minutes per mile) 16–19 9:34 12:09 20–24 9:30 11:44 25–29 10:03 11:42 30–34 10:09 12:29 How fast can a 13-year-old Run mph? For a 12–13yr old, the top speed usually is between […]

How long does it take for rust to eat through metal? Steel is a metal that holds a lot of iron, and let’s say, for instance, that steel is constantly surrounded by environmental factors like water and oxygen, the steel may start to see signs of rust in as little as 4-5 days. Can you […]

What are goals of power system? The goals of power system analysis are the following: To model or to execute per phase analysis of power system components. To monitor the voltage at different buses, real and reactive power flow between buses. To plan future expansion of the current system. What are the major components of […]

What is the difference between a law and a theory explain? Generally, laws describe what will happen in a given situation as demonstrable by a mathematical equation, whereas theories describe how the phenomenon happens. What do hypothesis and theory have in common? In science, a theory is a tested, well-substantiated, unifying explanation for a set […]
