Why gold leaves are used in Electroscope? A gold-leaf type electroscope is a device used to detect the presence of electric charge on a body and its relative amount. They also capture charge leaking through the air that could accumulate on the glass walls, and increase the sensitivity of the instrument. What happened when you […]
What is the function of hammer anvil stirrup?
What is the function of hammer anvil stirrup? Vibrations of the eardrum are in turn translated into oscillations of tiny bones (ossicles) found within the middle ear. The Hammer, Anvil, and Stirrup magnify the oscillations and relay this information to the chamber of the inner ear. What is a hammer in a ear? In ear […]
Should I charge my new phone overnight?
Should I charge my new phone overnight? “Do not leave your phone connected to the charger for long periods of time or overnight.” Huawei says, “Keeping your battery level as close to the middle (30% to 70%) as possible can effectively prolong the battery life.” The official word is to keep your phone charged – […]

What are the 4 parts of an animal cell? The components of a cell and their functions are described: membrane, cytoplasm, nucleus. What is the main function of an animal cell? Functions of Animal Cells A cell carries out all the processes of the body which includes producing energy and storing it, making proteins which […]
How do lysosomes work?
How do lysosomes work? A lysosome is a membrane-bound cell organelle that contains digestive enzymes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis. […]
When two variables decrease Together they are?
When two variables decrease Together they are? Positive correlation is a relationship between two variables in which both variables move in tandem—that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases. How do you find the relationship between […]
Is RNA the same as DNA?
Is RNA the same as DNA? There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine. What is RNA and function? The […]
Why only Tungsten is used in bulb?
Why only Tungsten is used in bulb? Tungsten is used for making filament of an electric bulb due to the following reasons: Being an alloy it has a very high melting point. It has very high resistivity so it does not burn easily at room temperature. The lamp glows at high temperatures. What is the […]
Which among Following is a noble gas?
What rollercoaster has the longest drop?
What rollercoaster has the longest drop? Kingda Ka How do drop towers slow down? And as Lenz’s law states, that magnetic field opposes the motion of the magnets. As a result, the magnetic field pushes up against the seat, causing the cart to slow down. This is how a drop tower ride’s magnetic brakes work. […]
