What is the distance from a concave mirror of focal length 25 cm? Answer Expert Verified We can Says that ,if object is Equal to image , For which that distance will be double to it’s focal Length. Therefore, the object Distance should be 50 Cm from the pole of the mirror. Where are periscopes […]
What is crust explain?
What is crust explain? “Crust” describes the outermost shell of a terrestrial planet. Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. […]
What is the critical approach to technology?
What is the critical approach to technology? Drawing inspiration from Marx’s approach, critical theory of technology argues that technology is both rational and biased. The design, development and eventual implementation of a technology are seen as normative processes through which interests and values are delegated to technological devices and systems. Does technology determine society? Technological […]
What are the two types of mixture and substance?
What are the two types of mixture and substance? A mixture is made when two or more substances are combined, but they are not combined chemically. There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures. Is oil and water a heterogeneous mixture? By definition, a pure substance or a homogeneous mixture consists […]

What happens to a wave when it reaches a barrier?
What happens to a wave when it reaches a barrier? Diffraction: A wave encountering a small obstacle tends to bend around the obstacle. This bending of the wavefront is called diffraction. When a wave encounters a barrier with an aperture, which is much smaller than the wavelength, the wave bends and spreads out as a […]
How do you know if a sample is representative?
How do you know if a sample is representative? A representative sample should be an unbiased reflection of what the population is like. There are many ways to evaluate representativeness—gender, age, socioeconomic status, profession, education, chronic illness, even personality or pet ownership. What percentage of sample is representative? For example, in a population of 1,000 […]

What is the thinnest liquid?
What is the thinnest liquid? Thanks to the “super material” graphene, a team of researchers managed to create one of the world’s thinnest layers of liquid. There’s now a new understanding of the word “wet” thanks to physicists who created the thinnest film of liquid ever. What is a viscous sauce? A sauce that runs […]
