What are the examples of sedimentary rock? Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash. What are sedimentary rocks give example? Some common […]

Why DC is not used in transformer?
Why DC is not used in transformer? Direct current(DC) has no time varying field because current is constant as well as there is no relatively motion between coil and core(magnetic circuit) of the transformer. Transformer fails to transfer power from primary to secondary. Thus DC supply is not used for transformer. Why does a capacitor […]
What is the main principle of colorimeter?
What is the main principle of colorimeter? In a colorimeter, a beam of light with a specific wavelength is passed through a solution via a series of lenses, which navigate the colored light to the measuring device. This analyzes the color compared to an existing standard. A microprocessor then calculates the absorbance or percent transmittance. […]
Do electric field lines exist?
Do electric field lines exist? Electric field lines never intersect. The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential. If the electric field in a given region of space is zero, electric field […]

What is the force of repulsion between two electrons?
What is the force of repulsion between two electrons? The force of repulsion of two +1.00 Coulomb charges held 1.00 meter apart is 9 billion Newton. This is an incredibly large force that compares in magnitude to the weight of more than 2000 jetliners. This problem was chosen primarily for its conceptual message. When two […]
What are the importance of energy in the society?
What are the importance of energy in the society? The use of energy is important to human society for handling problems in the environment. Developed societies use energy resources for agriculture, transportation, garbage collection, information technology and human communication. The use of energy has increased since the Industrial Revolution. What percentage of the economy is […]
What does tone mean when speaking?
What does tone mean when speaking? The definition of “tone of voice,” according to Merriam-Webster, is actually “the way a person is speaking to someone.” In essence, it’s how you sound when you say words out loud. How do you fix tone issues in writing? Let’s look at a few of the easiest and most […]
Is 0.9 correlation good?
Is 0.9 correlation good? The magnitude of the correlation coefficient indicates the strength of the association. For example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association. What does a correlation of 0.7 mean? CORRELATION COEFFICIENT BASICS The […]
