Which of the following is correct order of electron affinity? Therefore, the correct order of electron affinity is Cl > F > Br. What is greatest electron affinity? Fluorine is a small atom with a small amount of space available in its 2p orbital. Therefore, chlorine has a higher electron affinity than fluorine, and this […]
How are inclined planes used?
How are inclined planes used? Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade. The screw consists of a narrow inclined plane wrapped […]

What happens if someone drink sulfuric acid?
What happens if someone drink sulfuric acid? When the sulfuric acid is ingested, it can damage the internal organs e.g. burning holes in the stomach, because the acid rapidly decomposes proteins and lipids upon contact with living tissue. You should get help immediately! The higher the concentration, the more corrosive the acid. How do you […]
Will a ground fault trip a breaker?
Will a ground fault trip a breaker? A ground fault is a type of fault in which the unintentional pathway of the straying electrical current flows directly to the earth (to the ground). Like other types of short circuits, a ground fault causes the circuit breaker to trip due to the uncontrolled flow. How often […]
Does current increase as voltage increases?
Does current increase as voltage increases? According to Ohm’s Law, Current Increases when Voltage increases (I=V/R), but Current decreases when Voltage increases according to (P = VI) formula. Does voltage drop when current increases? Increasing the current causes a higher voltage drop across the internal resistance which reduces the source voltage. Some resistances increase their […]
Does a liquid release or absorb energy?
Does a liquid release or absorb energy? liquid absorbs energy to evaporate; liquid releases energy when to freeze. does a solid release or absorb energy when it changes into a liquid? when it sublimes into a gas? solids absorb energy to melt; solids absorb energy to sublime. Does a gas absorb energy as it changes […]
What is the use of Gaussian surface?
What is the use of Gaussian surface? A spherical Gaussian surface is used when finding the electric field or the flux produced by any of the following: a point charge. a uniformly distributed spherical shell of charge. any other charge distribution with spherical symmetry. What is the electric flux of cylinder? Considering a Gaussian surface […]
Which is harder basalt or granite?
Which is harder basalt or granite? Basalt weathers faster than granite because it is not as hard and it’s easier for outside substances to impact and manipulate its structure. What is special about granite? Granite has a density of around 162 pounds per cubic foot. Granite is one of the hardest substances in the world, […]
