Is water chemical energy? Water, like many substances, contains two kinds of energy. The first kind of energy is called kinetic energy. This is energy that is used during the execution of processes, such as movement. Because of kinetic energy water can flow and waves can exist. What form is energy stored in the human […]

Is FCC stronger than BCC? FCC and BCC also have many different measurements within the unit cell, as shown in the table below. Additionally, FCC metals tend to be more dense, more stable at high temperatures, and more ductile than BCC metals. This comes from their packing arrangement and slip systems. Why is it called […]

What is the principle of Electroscope? The working principle of an electroscope is based on the atomic structure of elements, charge induction, the internal structure of metal elements and the idea that like charges repel each other while unlike charges attract each other. What is the working of an Electroscope? ELECTROSCOPE : Electroscope is used […]

What is the advantages and disadvantages of renewable energy? Disadvantages of renewable energy resources Energy Resource Advantages Disadvantages Hydroelectric power stations Clean and cheap to run Expensive to set up and output could be affected by drought Solar cells Clean and cheap to run Not always sunny and output does not always outweigh initial cost […]

At what distance does a long straight wire carry a current? Answer. Magnetic field, We have to find the distance from a long straight wire that is carrying a current of 12 A. Hence, at 0.08 m from a long straight wire carrying a current of 12 A. What basic principle enables all electric generators? […]

Where does the sun go when it sets? Answer: The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that’s because Earth spins — toward the east. Where does the moon rise if the Earth rotates counter clockwise? The Earth rotates counter-clockwise on its axis […]
